Rating Methodology by Sector

Consumer Finance

The following applies to consumer finance companies that extend unsecured loans to private individuals in Japan and does not apply to credit card companies, credit sales companies, mortgage companies, and business money lending companies. JCR applies this rating methodology with the necessary changes in the indicators for analysis to overseas consumer finance companies, based on laws, accounting system, financial administration in which these entities are located.

1.Business base

(1)Characteristics of the industry

(i)Market scale

The consumer finance market has been noticeably contracting since the Money Lending Business Act was revised in fiscal 2006. In terms of the market scale, “Money Lending Business-Related Statistics” of the Financial Services Agency (FSA), monthly statistics compiled by the Japan Financial Services Association, and statistics released by the Japan Consumer Credit Association provide useful data, including loan balance. According to FSA’s statistics, the outstanding balance of unsecured consumer loans as of March 31, 2012 was 2.7 trillion yen, sharply dropping from 10.6 trillion yen as of March 31, 2006.

(ii)Competitive situation

In the unsecured loan business, the main competitors to consumer finance companies are banks, credit card companies, and sales credit companies. However, the customer base does not overlap with those of banks and credit card companies of banking groups in terms of salaries and other customer attributes. Before the Money Lending Business Act was revised in December 2006, competition in the consumer finance industry was very severe; the industry consisted of five major companies and other small and midsize money lenders. In light of the high profitability, a feature of the consumer finance business, there were even players who entered the business from the IT, railway, and other non-finance industries. However, since the revision of the Money Lending Business Act at the end of 2006, given the application of stricter regulations, the decline in risk taking ability, and the increase in the number of excess interest payment claims, the number of money lenders and the outstanding balance of loans had been declining steadily and the decline has been slowing down recently. Aiful Corporation and Takefuji Corporation, the two major money lenders, went bankrupt, filing for Alternative Dispute Resolution (ADR) in September 2009 and for bankruptcy in September 2010, respectively. Certain foreign companies also withdrew from the market. As a result, at present, only a

limited number of major companies are still extending new loans.

(iii)Customer bases and sales methods

The number of the populations aged between 20 years old and 64 years old in Japan is approximately 75 million, and that of salaried workers is approximately 46 million. The majority of users of the consumer finance companies are believed to be those with an annual salary of 5 million yen or less, or with an average annual income of around between 2 million yen and 3 million yen. The number of people who are categorized as people with an annual salary of 5 million yen or less by salary level is approximately 32 million (accounting for 70% of the total working population). Although they have halved since several years ago, the number of new customers appears to remain between 400,000 and 500,000. Considering these factors, although the market is still contracting, there is apparently a certain level of need. In addition to credit control of money lenders, the reluctance on the part of borrowers to take out loans to protect their living conditions is another reason for the contraction of the market.

Until around 2006, consumer finance companies built customer recognition using advertising, mainly through television, newspapers, and the internet. They encouraged customers to use unmanned loan machines, and extended loans to customers instantly when they needed them. This was then the main methods of extending loans. Since the revision of the Money Lending Business Act, excessive advertising and TV commercials have been regulated, and the content of advertising has become less direct. Given the rise in the public attention on the issue of heavily indebted people and the revision of the Money Lending Business Act, consumer finance companies have started to open consulting-type stores in recent years. Their traditional sales method was to increase the unit amount of loans by attracting customers through heavy advertising. With the circumstances described above, however, consumer finance companies are now in the phase of changing their sales method to a style in which, with the introduction of regulations that limit the total amount of loans to individual customers, they aim to acquire customers who need limited loans, but who will remain as customers for a long time, by applying more careful credit examinations. From an even longer-term perspective, it is necessary to respond to the effects of the decrease in numbers of young customers by the declining birthrate and the aging of Japanese society.

(iv)Regulations

The consumer finance companies are required to register under the Money Lending Business Act. They are not in the position in which they can expect public support in the same manner as banks do.

A.Change of the upper limit for loan interest rates

Following the revision of the upper limit of interest rates stipulated in the Investment Act in June 2000, the upper limit of loan interest rates was lowered to 29.2%, from the 40.004% that was previously used. In the case of money lenders, until recently, when certain requirements were met,

they could use interest rates in the range between the upper limit of interest rates stipulated in the Investment Act and that of the Interest Rate Restriction Act (the so-called grey zone interest rates).

As a result, many money lenders were managing operations based on the interest rate range mentioned above. However, following the revision of the Money Lending Business Act at the end of 2006, the enforcement of Article 4 meant that, from June 18, 2010, the upper limit of interest rates in the Investment Act was lowered to 20%, abolishing the grey zone interest rates. As a result, the upper limit of interest rates has become the level stipulated in the Interest Rate Restriction Act (between 15% and 20% depending on the loan amount). Loans with interest rates that exceed the upper limit as stipulated in the Interest Rate Restriction Act are invalid under civil law, and can be subject to administrative penalties. Loans that are extended with interest rates that exceed the upper limit as stipulated in the Investment Act are subject to criminal punishment.

B.Revision of the Money Lending Business Act

The Money Lending Business Act was revised (and adopted) in December 2006, reflecting the importance of solving the issue of heavily indebted people and the importance of the role that the money lending business plays in the economy. Accordingly, the legal restrictions were strengthened in stages over approximately three and half years, from the enforcement of Article 1 in January 2007 to that of Article 4 in June 2010. The main features of the revision were the strengthening of the requirements for the registration of money lenders, the establishment of a system for a designated credit information organization, the strengthening of rules on excessive loans, and the lowering of the upper limit of interest rates (as described in (i) above). The resultant effects that money lenders particularly felt were a decline in risk taking ability, as a result of the lower upper limit of interest rates, and the establishment of an upper limit of loan amounts, as a result of the introduction of the restriction on the total loan amount. As a result, the operations of money lenders are now restricted in terms of both the amount (the outstanding balance) and rate (interest rates). This has significantly impacted the operating results and management strategies of money lenders. Coupled with the burden of meeting excess interest repayment claims (described below), the number of withdrawals from the business and the number of the bankruptcies of small and medium companies has increased.

(v)Excess interest repayment claims

In January 2006, the Supreme Court decided to radically change its judgment standard related to the application of the rules of deemed reimbursement, as stipulated in the former Money-Lending Business Control and Regulation Law. Following this, the deemed reimbursement rules of the former law were to all intents and purposes dead. The subsequent surge in demands for the repayment of excess interest has significantly impacted the management of not only consumer finance companies, but also other money lenders, including sales credit companies and credit card companies. The change of the standard by the Supreme Court suddenly inspired deliberations on revising the Money Lending

Business Act (formally the Money-Lending Business Control and Regulation Law) as described above, and became one of the factors attributable to the revision of the law (as described in 4) (ii) above).

(2)Market position and competitiveness

Consumer finance companies extend small loans to a large number of customers through advanced computerized operations that are based on a manual. As a result, economies of scale are a feature of the consumer finance business. It is consequently always important for the business to acquire and maintain

a certain level when it comes to the outstanding balance of loans and number of customers.

Before the revision of the Money Lending Business Act in 2006, consumer finance companies sought to bolster their product and corporate image, particularly through commercial messages on TV that used celebrities and pets. These activities then played a significant role in attracting customers. In addition, because the loyalty of customers was not intrinsically high, the key point for customers when selecting a consumer finance company was the ability of the company in question to promptly lend them money. Since the revision of the Money Lending Business Act, however, the situation has changed completely, and sales performance is now determined by the ability to raise funds and by financial strength.

With the earnings and financial situation made difficult by the outflows of cash due to excess interest repayment claims, consumer finance companies are finding it harder to carry out aggressive sales initiatives than before. Advertising activities through commercial messages on television and in other media have slowed, and credit examination standards are more severe. As a result, the number of new customers acquired by consumer finance companies has halved. It is necessary for consumer finance companies to create their own new image, which will boost recognition from general society and give customers the assurance to encourage long-term relationships, and raise their brand power. It will apparently take a few more years before the consumer finance companies can move away from the effects of the excess interest repayment claims. Over the medium to long term, however, it is necessary for the consumer finance companies to restart active sales to halt the fall in the number of customers and the outstanding balance of loans. Funding capabilities, management policies, sales initiatives, and the availability of support from shareholders are factors that differentiate the companies in terms of their competitiveness. As an example of support from shareholders, some consumer finance companies affiliated with banking groups have bolstered the outstanding balance of guarantees through the use of the sales foundations of banks and with the banks’ cooperation, and certain positive results are seen in terms earnings.

Sales foundations are evaluated based on main channels, the strength to control those main channels, the number and the degree of dispersion of customers, the balance of channels and product services, and an analysis of the strengths and weaknesses. A good balance of risk and return, which is also related to the strength of sales foundations, is an important factor in examining the continuation of

the business.

The operations of consumer finance companies are supported by alliances with major financial institutions in various aspects, including funding, the expansion of the guarantee business, the development of overseas businesses, and the acquisition of customers. Since the revision of the Money Lending Business Act, the effects on sales activities from support of their parent companies have become more apparent.

(3)Management

JCR focuses on certain aspects, including (i) the constitution of managers and the stability and the independence of management, (ii) the strengths and the weaknesses of each company in light of opportunities and threats in the business environment (the SWOT analysis), (iii) governance, and (iv) the degree of risks against harmful rumors.

As a result of two events—the sharp rise in the number of excess interest repayment claims and the revision of the Money Lending Business Act—the management environment for money lenders has changed dramatically. Consequently, the money lenders have been forced to respond to changes and adopt reforms. Excess interest repayment claims have resulted in heavy unexpected expenses, and the revision of the Money Lending Business Act has lowered the profitability of loan operations. In response, consumer finance companies have made extensive efforts to streamline their management over the last few years. With the deterioration in their operating environment, instances of consumer finance companies choosing to become members of groups centered on major banks have been rising.

With respect to the companies already affiliated with banking groups, JCR interviews them about the outlook of their roles and position within the relevant group and examines the results to be included in rating considerations, along with the financial standing of each company. As for the companies that do not belong to any business groups, to determine whether or not they can continue to operate independently, JCR examines such factors as the overall balance of the business base, profitability, financial strength, and funding capabilities.

2.Financial base

(1)Capital adequacy

JCR examines if consumer finance companies have adequate shareholders’ equity in terms of both quality and quantity against the risks they are taking. With respect to the quantity of shareholders’ equity, JCR examines the absolute size of shareholders’ equity and its size in relation to the level of risks. With respect to quality, JCR examines the level of capital that relies on tax effects and securities that have a fixed term or that can be redeemed. It also analyzes the level of the equity ratio (by making adjustments to off-balance sheet transactions, deferred tax assets, goodwill, and other items, when necessary). To determine the scale and details of risks, JCR comprehensively examines the main businesses (the core businesses of the consumer finance industry are unsecured loans, the guarantee business, and the

servicer), the details of assets, and the sales foundations. As a result of excess interest repayment claims, the financial strength of the consumer finance companies has deteriorated significantly. Consequently, JCR also examines whether or not the consumer finance companies have the level of capital and allowances that is adequate for dealing with risks that may take place in the next three years or so.

Key financial indicators:

■Equity ratio

■Equity ratio after adjustments for off-balance sheet transactions

■Ratio of cash-out amount due to excess interest repayment to the sum of shareholders’ equity and allowances

(2)Quality of assets

JCR examines the ratio of operating assets in light of asset turnover (the average maturity period) and liabilities (the coverage ratio of liabilities by assets). It also examines the degree of dispersion of borrowers and claims, the ratio of non-performing loans, the rate of write-offs, the collection rate, unrealized losses, and the adequacy of the allowance for non-performing loans. JCR also looks into channels for acquiring assets, operating positions, credit policies, and the structures of management and collection from a qualitative perspective. Because there is a chance of a mismatch between the periods of management and funding (the so-called duration gap), it is important to pay close attention to the extension of the collection period of assets that are under management.

The consumer finance, credit card, and sales credit industries face a unique issue in the form of interest repayment loss. The provision for a loss on interest repayments is a provision that was established in response to the sharp increase in excess interest repayment claims in 2006. Analyzing this allowance requires special attention, because each company has different reporting methods. First, the difference between the provision for the loss on interest repayment and the allowance for doubtful accounts needs to be clarified. When excess interest is repaid, repayments can be made by offsetting against the principal (principal offsetting), or, if the principal is not large enough to offset repayments, the companies make repayments using their own funds (cash-out). Accordingly, there are two methods for reporting the provision for the loss on interest repayments. One method is to include both principal offsetting and cash-out in the scope of the provision for the loss on interest repayments. Another method is to only include cash-out in the scope of the provision for the loss on interest repayments, and include principal offsetting in the allowance for doubtful accounts. Consumer finance companies are free to adopt either of these two methods. For this reason, to compare provisions among the companies, it is often easier to analyze provisions based on the total allowance for doubtful accounts and the provision for the loss on interest repayments. Second, there are two methods of recording provisions. One method is to provide an allowance for all expected future excess repayments at once. The allowance is only reversed (objective use) when necessary. Based on this method, expenses related to the provision for the loss on interest repayments are not incurred in ordinary terms, but only in the term when the provision is

made. Another method is to recalculate the amount necessary for the provision for the loss on interest repayments at the end of each term, and if the outstanding balance of the provision (after the reversal is made for each purpose) is short of the amount calculated above, an additional provision for the loss on interest repayments will be made. Under this method, the provision for the loss on interest repayments is recorded in the income statement each term. Consumer finance companies are, once again, able to adopt either of these two methods. Close attention needs to be paid to consumer finance companies that adopt the first method, because if problems of excessive interest repayments persist longer than initially anticipated, the companies will take additional measures, and a noticeable impact from these measures tend to appear suddenly. With the number of excess interest repayment claims being declining year-on-year for each business category, changes are becoming apparent now in the trend. However, it is necessary to watch closely when the problem of excess interest repayment can end and how much allowance for loss on excess interest repayment can remain at that time.

Key financial indicators:

■Delinquency rate

■Write-off ratio

■Allowance coverage ratio

■The number of disclosure requests (when available), the number of repayment requests, the amount of repayments, and the damage to the principal, and other matters related to interest repayments ■Credit costs against operating assets

■Credit costs against accounts of profit and loss in the term

■The outstanding balance of loans per customer on average

(3)Earnings Strength

JCR analyzes profit stability, the asset income ratio, and the cost structure. Consumer finance companies make most of their income in the form of interest from loans, guarantee commissions, and other income. However, interest from loans has been falling consistently, in step with the decline in the outstanding balance of loans and the drop in interest rates. Therefore, the stability of income is clearly affected by the scale of the outstanding balance of loans, the level of guarantee commissions and other supplementary income. When analyzing return on assets (ROA), JCR refers to the figure that is calculated by dividing the sum of total assets and operating assets by the sum of income before credit costs, ordinary income, and net income. As for indicators for the efficiency, JCR focuses on indicators per employee (the outstanding balance of operating assets and loans, and earnings) and the overhead ratio (OHR: Selling, general, and administrative expenses excluding expenses for doubtful accounts/gross profit). If the amount of loans and the outstanding balance of loans continue to decline because of the contraction of the scale of the business, the companies’ operations are nearing breakeven point. In this case, it is also very important to focus on the progress and the possibility of business restructuring.

Key financial indicators:

■Indicators per employee (the outstanding balance of operating assets, and earnings)

■OHR

■ROA

■Investment yields

(4)Liquidity

It is important to note that funding is purchasing for the consumer finance companies, and it is the key factor that directly impacts on not only earnings, but also management stability and credibility.

Consumer finance companies have a slight duration gap between fund management and financing, and the burden of meeting excess interest repayment claims. As a result, even in normal times, they finance their debt repayments through refinancing, securitization, and other funding measures, in addition to free cash flows. Consequently, when evaluating consumer finance companies, significant consideration is given to maintaining stable trading relationships with financial institutions to ensure that refinancing and the roll-over of CP is carried out smoothly, and to spare funding capacities or short-term liquidity in dealing with temporary turmoil in the market for direct financing. In particular, from around the time the Money Lending Business Act was revised in 2006, financial institutions have adopted a much more severe stance in extending loans to the consumer finance industry, and this is unlikely to change in the near future. It is therefore critical for consumer finance companies to have core financial institutions and to maintain sound relationships with them. When a consumer finance company has a bank as its parent company or as its main shareholder, that company is often judged to have secure funding foundations.

On the other hand, if a consumer finance company has poor funding capabilities, it often fails to bolster operating claims or even reduce such claims, due to the financial restraints. It will face a contraction in its operating foundations and may eventually fail in the worst-case scenario. For this reason, close attention needs to be paid to such a company.

With respect to financing, JCR examines the balance between long-term financing and short-term financing, the balance between fixed interest rates and variable interest rates, the balance between direct financing and indirect financing, the constitution of financial institutions from which loans are extended, the constitution of methods of direct financing (including SB, CP, and credit securitization), the level of interest rates for loans payable, the provision of collateral, and the policy and practice of covenants.

Based on this examination, JCR judges whether or not appropriate financing is carried out from the perspective of funding stability and costs.

With respect to long-term financing, JCR focuses on repayment and redemption schedules, and confirms whether or not there is a time in the future when a large amount of funds will need to be repaid.

If there is such a time, it also confirms the policies of the company on financing (and collateral, if necessary) for such payments.

If covenants are attached to syndicated loans, credit securitization, and other instruments, JCR

examines the possibility of applying those covenants and, if they have been applied, looks at the kinds of agreements that have been made. If the possibility of applying these covenants is judged to be high, JCR examines the policies for preparing for such an event and measures taken, as well as the reality of the policies.

Key financial indicators:

■The level of short-term liquidity

■The direct financing ratio and the short-term financing ratio

■The provision of collateral and surplus collateral provision capacity (surplus of collateral assets )

(Note) Individual companies are analyzed based on multiple perspectives, including capital adequacy, asset quality, management, earnings, liquidity, sensitivity to market risk (CAMELS), operating base (franchise value), and parent-subsidiary relationships (support) in addition to such external factors as the business environment. The order, importance, and levels of assessment weight are not related, and

a comprehensive judgment is made based on multifaceted examination and these aspects. Similar to

the way the balance between risk and return is emphasized, these factors are also connected to one another for additional analysis.

特殊钢一般是指具有特殊性能或特殊用途的钢种

特殊钢一般是指具有特殊性能或特殊用途的钢种。其与普通钢相比具有更高 的强度和韧性、物理性能、化学性能、生物相容性和工艺性能。因其性能特殊, 决定了它在国民经济及军事工业中占有极其重要的地位。因此,在生产制造特 殊钢时,就需要采用特殊的工艺装备技术来实现特殊的化学成分、特殊的组织 和性能。 特殊钢的定义在国际上没有明确规定,各国特殊钢的统计分类不完全相同。 我国特殊钢定义与日本、欧洲相近,包括优质碳素钢、合金钢、高合金钢三大类, 通常展开为优质碳素结构钢、合金结构钢、碳素工具钢、合金工具钢、高速工具 钢、轴承钢、弹簧钢(碳素弹簧钢和合金弹簧钢)、耐热钢和不锈钢。由于高温合 金与精密合金在特殊钢厂生产,也将这两种合金纳入特殊钢的行列之中统计[1]。在 特殊钢领域,除优质碳素结构钢、碳素工具钢和碳素弹簧钢外,其余均为合金钢, 合金钢约占特殊钢的70%。目前,世界上特殊钢有近2 000个牌号、约50 000个品种 规格、数百个检验标准。

随着科学技术的发展,对特殊钢产量及品种的需要日益扩大,对质量的要求也越 来越严格、苛刻。近年来,围绕提高特殊钢性能、质量、品种、效率,降低特殊钢成 本、节能降耗、环境友好等方面采用了一系列新技术、新工艺、新装备,使得特殊钢 的洁净度、均匀度、组织细化度和尺寸精度等有了很大提高。 特殊钢生产工艺流程主要有3种[2]:1)电炉流程(即短流程): 电炉—二次精炼 —xx—轧制。2)转炉流程(长流程): 高炉—铁水预处理—转炉—二次精炼—xx —轧制。3)特种冶金: 特种冶炼(如真空感应熔炼、冷坩埚熔炼、电渣重熔、真空电 弧重熔、电子束熔炼、等离子熔炼等)—锻造或轧制。 这里要指出的是有些钢种的生产至今还必须走模铸—开坯—轧制或锻造的工艺流程。 因早期特殊钢主要采用电弧炉工艺冶炼,习惯上形成了特殊钢一定要用电炉冶炼,特殊钢厂就是电炉钢厂。而客观事实上也的确存在电炉只有生产特殊钢才可以有好的经济效益,特殊钢只能由电炉冶炼。这主要是由于早期电炉炼钢的特点和特殊钢本身的性质所决定的:1)电炉用废钢中有可利用的合金元素;2)电炉炼钢是靠电弧进行加热的,其温度远远超过2 000℃,且钢水温度可长时间地精确控制,这样电炉炼钢在难熔合金冶炼、合金化成分及工艺柔性等方面较转炉炼钢有无比的优越性;3)不足是炼钢周期长,生产效率低,成本高(废钢、电价昂贵),炉容小,易增碳、吸氮等。

关于国外建筑节能技术的研究

关于国外建筑节能技术的研究 国外建筑物节能技术注重从建筑设计、建筑维护结构、建筑材料及密封角度, 系统采用相关的技术手段来维持建筑体能——建筑从与其共生的环境中汲取的储存在建筑体内的能量,降低建筑整个寿命周期中的能耗. 一、充分利用自然环境进行建筑节能设计. 日本于上世纪 90 年代提出了“与环境共生住宅”理念, 强调建筑立面设计技术、自然采光、通风技术、太阳能供电系统、分区空调系统( 工作区和非工作区) 、智能照明系统、分区热水采暖和制冷系统、水回收系统等设计与环境、气候协调的建筑是节能的重要方法。 如对两幢相邻建筑的设计, 可从太阳辐射的角度研究建筑高度和设计之间的关系,随着两幢建筑之间的空隙增加, 靠近空隙的建筑外立面的太阳辐射值减少, 为了降低建筑表面的太阳辐射, 设计建筑立面( 除了北墙之外) 高宽比小于2∶1 并根据需要增设遮阳装置可达到节能目的。 二、建筑材料节能设计技术 建筑维护结构是建筑和与其共生环境之间发生热交换的直接途径, 因此成为节能设计研究热点. (1)采用复合墙体结构技术增加墙体保温隔热性能. 复合墙体结构技术, 是指通过在墙体的主要结构基础上采用高

效保温隔热材料附着或填入墙体内, 以提高墙体的热阻, 改善整个墙体的热工性能. 根据复合材料与主体结构位置的不同, 分为外墙内保温技术、外墙外保温技术及夹芯保温技术. 英国在墙体节能上采用两种做法: 在传统的砌块墙体上钻眼, 向空气间层内喷入轻质散状保温材料, 如聚苯颗粒或岩棉等, 直至将空气间层全部填充满, 墙体保温效能可大大提高; 在外墙上进行外保温, 如英国的贝丁顿零能耗发展项目位于伦敦附近的萨顿市, 由英国著名的生态建筑师Bill Dunster设计. 在此小区设计中,为了减少建筑能耗, 设计者探索了一种零采暖住宅模式, 维护结构采用夹层墙体, 中间为300 mm的保温层填充空腔, 外层采用防水砖块或防水木结构, 两边用不锈钢固定。 保温层的U值为0.1( W/ ( m2·℃) ) , 能够有效地隔热和吸收太阳能. 利用市政污水处理厂下面的污泥加上其他垃圾和粘土, 可生产出一种新型的适应建筑的陶瓷砖. 与传统的陶瓷砖相比, 采用这种新型的生态砖, 耗能可降低49% , 太阳能的利用增加14%。

建筑围护结构节能技术 引言: 建筑围护结构系指墙体、屋面、地面以及门窗,其保温、隔热、密封性等工作性能的提高,可以大大降低建筑物能量负荷,从而减少建筑设备的能耗、节省 能源。所以提高建筑围护结构的热工性能是建筑节能的一项重要措施。在建筑物的四大围护结构门窗、墙体、屋顶和地面中,以面积与能量损失率计,第一位的是门窗,其次是墙体,最后是屋顶。又数据表明,从门窗跑掉的能量约占建筑使用过程中总能耗的50%其耗能约是墙体的4倍、屋顶的5倍、地面的20倍。 因此,门窗、墙体及屋顶这三种围护结构的节能技术就成为建筑可持续发展关注的焦点。围护结构节能主要发展方向是,开发高效、经济的保温、隔热材料和切实可行的构造技术,以提高围护结构的保温、隔热性能和密闭性能,减少围护结构的能量损失。特别值得指出的是,围护结构节能建设的投入产出比很高。 有资料表明,要使建筑节能率提高20%g 40%其增强围护结构的投入只需比总投资提高3%g 6%^卩可实现,节能收益不可忽视。为此,通过以下几个方面阐述提高建筑围护结构的措施。 、建筑节能材料 1、建筑墙体节能材料建筑材料的选择直接影响建筑的耗热量,其所用材料的保温性能:其一是要满足结构要求,如承载、抗剪等方面的要求,需要外墙材料具有较高的结构强度;二是满足保温要求,又需要外墙材料具有较低的导热系数。节能建筑的外墙若采用单一材料,其满足保温要求的厚度一般都超过满足结构要求的厚度。根本的出路,则是把结构层与保温层分开,用强度指标较高的 材料作为外墙结构层,用高效保温材料作为外墙保温层,两者结合起来,形成墙体厚度适宜,既满足结构要求又满足节能保温要求的复合。空心粘土砖墙体、混凝土砌块墙体稻草板墙体,新型VIP真空隔热板墙体以及墙体节能与太阳能的利用等目前都在不断完善发展,应在具体使用过程中根据其自身特点进行。 2、节能建筑的门窗材料在建筑围护结构的四大构件中,门窗的绝热性能最差,是影响室内热环境和建筑节能的最主要因素,占建筑围护构件总能耗的近50%。所以在保证日照、采光、通风、观景要求的条件下,尽量选择导热率较小材料提高门窗本身的保温性能。 建筑门窗一般由门窗框材料、镶嵌材料和密封材料构成。门窗框材料有木材、刚材、铝合金、塑料和复合材料等。经过复合、表面处理后的材料(铝合金与高性能工程塑料复合的铝合金型材,经粉末喷涂、佛碳喷涂等表面处理)占目前的主要地位。镶嵌材料常见的为玻璃制品,能作为节能玻璃的当前已有抽真空玻璃、可调节玻璃等,特点

浅析日本传统町屋建筑特色

浅析日本传统町屋建筑特色 学号:080907108 姓名:韩婷 专业:城市规划 指导老师:任君

浅析日本传统町屋建筑特色 摘要:日本民族具有的尊重自然、单纯、质朴的文化精神,使这个向来奉行拿来主义的民族,对其民宅建筑、神社、寺院、古堡的传统建筑风格有着一种根深蒂固的坚持。与自然的和谐统一是日本建筑的主要特点。町屋是日本中世纪以来城市住宅的典型样式,具有丰富的民族文化内涵。通过对传统建筑风格及生活方式的坚持,使城市的古都风貌得以传承,这是日本传统建筑保护的一贯做法。 关键词:町屋,自然主义,木造 住居,不管在哪个时代,都反映了当时的社会现象。在这个意义上,它可以说是文化的结晶。……住在住居里的人,建设住居的人,以及围绕着这些人的社会,当所有这些元素和谐统一的住居诞生时,它就成为了文化。 町屋是日本中世以来城市住宅的典型样式,具有丰富的民族文化内涵,作为日本独特的历史文化和自然气候条件的产物.它的设计清晰地反映了日本传统的自然主义建筑观。 日本人在公元七世纪的时候,受气候和空间条件的影响,把狭窄的居室进行了功能安排,比如,在唯一的房间进行“污”“洁”分区,分成铺素土的“土间”和铺席子草垫的“土座”:前者不脱鞋,烧火做饭;后者要脱鞋,吃饭睡觉。不久,他们也由此建立了以榻榻米为模数的空间分割,又在一个房间内,实现了多功能的叠加--白天会客、晚上睡觉。但直到明治维新,日本人在“和魂洋才”的西方文化渗透之下,才逐渐改进了他们居住的一些弊端,比如,厨房将终于摆脱了原有的跪坐式,变为站立式操作台,室内开始设立卫生间。 町屋为木格子架结构,是日本传统的连体式建筑,显示了日本传统城市住宅特有的空间意象。作为传统京都住宅,町屋相当于中国城市中的街屋或店铺住宅,町屋的特色是木造,楼高两层,狭长的基地,前店后住,中间是安静的庭院。当时的日本商人们和手工艺者将町屋作为他们工作和居住的场所。 以“京町家”为例,从形体、布局和室内装饰等多方面都显示了日本传统城市住宅特有的空间意象,及其对京都等城市的景观意象的影响,平与同时期的中国江南民居建筑进行了对比,以揭示影响传统人居环境设计的一些共同因素。 其特色可以从以下几方面说明: 1.木材的实用 町屋的建造特点在于木材,从高床式的地台到立面门窗、屋架无不以木为才。日本人对大自然内的灵性的探讨以及在发挥材料本性的表现方面十分独特,他们的建筑中充分发挥了材料本来所特有的材质、肌理、色彩等。 题本古代所有的建筑样式都是由木结构技术发展而来从最早8世纪的法隆寺到每20年就原样重修一次的伊势神宫都是如此。町屋最早是草顶和木屋顶,知道16世纪室町时代,日本的住宅屋顶仍是以草顶或木屋顶为主。日本盛产桧柏和杉等性能极佳的木材,它们纹理美观,用于建筑时大多不加任何油饰。桧柏和杉都是针叶树,材质柔软,切削时用锐利的刀具开成平滑的肌量,在这样的建筑中人们可以感受到木的材质。除木材之外,日本匠师还是使用其它各种天然材料的能手。竹节、木纹、石理经过匠师们的精心安排,都以纯素的形式交汇成日本建筑特有的魅力。

日本十大经典动漫介绍

第一位:七龙珠 可以毫不夸张的说,《龙珠》的诞生标志着日本漫画走向颠峰。 创造“龙珠”神话的是一个懒散却充满想象力的年轻人。鸟山明没有上过大学,19岁从爱知县县立工业高中设计科毕业之后,他就进入了名古屋一家广告设计公司设计广告画。然而还很年轻的他做事并不卖力,在那里工作的三年时间里几乎天天迟到,到后来老板即将炒他鱿鱼的时候,鸟山明自己提出辞职。鸟山明的美术功底其实并不是很好,然而拥有丰富想象力的他对于漫画却有着满腔热情。有一次正处于失业状态的鸟山明看到了《少年跳跃》稿酬丰厚的征稿启事,于是开始创作其第一部漫画。不过鸟山明的这部处女作并没有入选。尽管如此鸟山明并没有放弃,仍旧不断向《少年跳跃》投稿,结果被退稿100多次。直到1978年,鸟山明的“岛上漫游”终于在《少年跳跃》上刊出。1979年,鸟山明的成名作《阿拉蕾》开始在《少年跳跃》上连载,这部充满想象力的搞笑之作立刻获得成功,1981年动画版《阿拉蕾》播出,“阿拉蕾”成为当年最著名的漫画形象,各种相关产品充斥大街小巷,这一年被人称为“阿拉蕾年”。 真正让鸟山明成为日本漫坛教父的是1984年的《龙珠》。鸟山明在创作《阿拉蕾》的过程中经常看成龙的电影寻找灵感,功夫电影看得多了,鸟山明就想到创作一部功夫漫画,于是一部叫做《骑龙少年》的漫画就这样构思起来了。这部漫画尝试性刊载之后获得了好评,于是鸟山明决定退出《阿拉蕾》的创作,开始新漫画的连载,这就是《龙珠》。《龙珠》造成了比《阿拉蕾》更大的轰动,1986年动画版播出后,《龙珠》成为当时最受欢迎的漫画作品。而鸟山明本人也成为手冢治虫之后日本漫坛的又一个漫画之神,当时鸟山明因为居住地送稿不方便而准备迁离原居地,当地政府为了挽留他,特地在鸟山明家到机场之间修了一条高速公路。 第二位:游戏王 1998年“口袋妖怪”的一系列对战卡片在市面上大为风靡,一时之间,卡片游戏的热潮席卷全球,在少年儿童之间的影响力逐日攀升。而以卡片游戏为题

国内外特殊钢产业发展现状与工艺技术比较

国内外特殊钢产业发展现状与工艺技术比较 点击次数:9 发表时间:2013-5-31 13:25:38 所属分类:工作学习 一、现状研究 特殊钢是重大装备制造和国家重点工程建设所需的关键材料,是钢铁材料中的高技术含量产品,其生产和应用代表了一个国家的工业化发展水平。虽然中国已是名副其实的钢铁生产大国,但还不能称为钢铁强国,中国钢铁质量尤其是特殊钢质量水平还落后于日、美、欧等发达国家。 发展现代国防军工、高速铁路和电气化铁路、发展国产轿车制造业、油田开采设备换代、轴承行业装备换代、研制现代化的新型武器装备等,都需要高性能的特钢产品作为关键材料。在中国装备制造业升级换代时,也需要越来越多的特钢支持。从某种程度上来说,特钢行业将会成为中国经济发展的一个基础行业,其发展将直接影响中国其他关键行业的发展。因此高品质特殊钢成为国家“十二五”重点扶植的战略新兴产业中新材料之一。 1.特殊钢产业国际发展现状 全球优特钢年产量约8000万t,占粗钢总量10%左右。世界特殊钢生产主要集中在日、美、德、法、英、意大利、韩国和瑞典,这些国家特殊钢年产量550 0万t左右,约占世界特殊钢产量的70%。工业发达国家的特钢产量一般占15%~ 20%,其中瑞典比例最高,达50%,其次为德国22%,日本19%,意大利17%,韩国13%,中国仅为5%。 特殊钢产业总体水平最高的国家首推日本和德国。日本特钢产量占世界特钢产量的23%,达2300万t。德国特钢产量占据世界特钢产量的20%。其他一些发达国家在某些特殊钢品种上居领先地位,如瑞典是世界上“特殊钢比重”最高的国家,其OVAKO公司的轴承钢、山德维克公司的工模具钢在国际上具有很高的知名度;法国的不锈钢和精密合金、奥地利的工模具钢、美国和英国的高温合金都处于国际一流水平。 2.特殊钢产业国内发展现状

浅谈日本建筑抗震技术

浅谈日本建筑抗震技术 摘要:日本每年发生有感地震约1000多次,其中6级以上的地震每年至少发生1次。频繁的地震灾害使日本的抗震技术快速发展、完善,并形成了比较完整的技术体系。本文将介绍日本建筑抗震技术体系的各个方面,希望能为同样是地震重灾国的我国,提供借鉴,引起更多研究者的思考。 关键词:耐震,减振,免震,强震观测,振动台 0引言 据我国国家地震台网测定,北京时间2011年1月3日4时20分,在智利中部发生7.1级地震。这是距离我们最近的一次大地震。地震一直是伴随着人类文明发展的重大自然灾害之一。日本是世界公认的地震重灾国,每年发生有感地震约1000多次,全球10%的地震均发生在日本及其周边地区。其中6级以上的地震每年至少发生1次。[1]如图1、2所示。然而,频繁的地震灾害,却使日本的抗震技术快速发展、完善,并形成了比较完整的技术体系。自1998年至2007年,日本共发生震级为6.0以上的地震199次,约占全球同等规模地震总数961的20.7%左右,但由其导致的灾害死亡人数仅占世界的9%(中国却占约30%)。由此可见,日本抗震技术体系的先进与完善。 图1 全球地震分布图2 日本周边发生过的地震 1.日本的地理概况 日本位于亚欧大陆东端,陆地面积377880平方公里。由于日本列岛正好位于亚欧板块与太平洋板块交界处,按照地质板块学说,太平洋板块比较薄,密度比较大,而位置相对低一些。当太平洋板块向西呈水平移动时,它就会俯冲到相邻的亚欧板块之下。于是,当亚欧板块与太平洋板块发生碰撞、挤压时,两大板块交界处的岩层便出现变形、断裂等运动,从而产生火山爆发、地震等。 2.日本建筑抗震发展历史 由于日本地震多发,很早日本就对建筑的抗震性能进行研究。早在一百多年前,1891年浓尾大地震砖结构建筑被毁严重时,就开始探讨采取什么措施,来抵御地震破坏。 20世纪初,日本学者大森房吉提出近似分析地震动影响的静力计算法。日本从美国引进钢结构和钢筋混凝土结构技术后,不久,日本的钢结构建筑创始人、东京大学教授佐野利器于1914年发表了《家屋抗震结构论》。首先提出了“抗震结构”的概念,并创造性提出了用“静态”的水平力,代替“动态”的地震力的“度震法”,来进行建筑结构的抗震计算,为现代结构抗震的计算奠定了基础。

冷镦钢所用的高性能特钢线材

冷镦钢所用的高性能特钢线材 摘要 特殊钢线棒材的最终主要用途是在汽车使用中的重要安全部分。为了得到最终产品,后续工序如:退火,拉拔,加工,锻造成型过程的热、冷温度区域的二次加工;以及热处理过程如淬火、回火都是必需的。为了降低成本以及节约能源,特钢线棒材非常需要省略退火工序和延长锻模的寿命。本文概述了可以省去离线退火过程的那些“在线软化(DS)-硼钢”、“DS-碳钢”和“DS-低合金钢”材料的主要属性。在线软化(DS)热处理技术的改进制造手段首先由NSC(美国国家安全委员会)提出。 1.介绍 那些大部分被用于与汽车安全有关部位的特钢线棒材都要通过后处理工艺流程步骤如退火、拉拔、加工、热冷锻造;以及热处理过程如淬火、回火等。为了降低总的生产制造成本,这些钢需要在转变为最终产品的时候,尽可能的减少一系列的加工工序以及减少锻造过程中的模具损耗量。本文将介绍新日铁公司冷锻用高性能线材产品,基于起源于该公司的在线特殊热处理,能够取消离线软化退火工序,以及延长锻模的使用寿命。 2.冷镦钢所用高性能线材 (在线软化线材) 2.1.用于延长锻造期的硼钢 螺栓大多都是用中碳钢、或者中碳低合金钢如日本工业标准的优质碳素钢(SWRCH 45K)、铬钼合金钢(SCM 435H),通过软化,球化退火,冷锻成螺栓的形状,再经淬火,回火制作而成。近年来为了降低螺栓制造成本,硼钢已经逐步取代了优质碳素钢(SWRCH 45K)。硼钢是一种降低了碳含量以及其他合金元素的钢种,其可以降低热轧制过程中的抗拉强度,同时由于硼元素的加入,减少了钢中其他合金元素的含量,从而降低了钢种的硬度。硼钢的优势在于它降低了生产及后处理工艺流程的成本,但是它的热轧抗拉强度并没有优质碳素钢(SWRCH 45K)在球化退火后的低,因此在延长锻模寿命效果上并没有达到预期效果。为了得到相当于或者比优质碳素钢(SWRCH 45K)的球化退火效果更低的抗拉强度,新日铁公司运用了他们自创的在线特殊热处理工艺流程来解决这一问题。 图表1.将改进后的硼钢与传统的硼钢的抗拉强度作比较。鉴于热轧抗拉强度的图表,可以看出传统的硼钢要比经过球化退火的优质碳素钢(SWRCH45K-SA)高出将近50MPa,而通过在线热处理技术改进后的硼钢的抗拉强度只有500MPa,效果相当于经过球化退火的优质碳素钢(SWRCH45K-SA)。从图表2.的结果可以看出,改进后的硼钢抗压缩变形力要比传统工艺的硼钢压力小50Mpa。由图表3.可见,改进后的硼钢锻模的使用寿命是传统热轧硼钢的三倍。通过在线热处理手段得到的硼钢,解决了长期以来锻模寿命较短的问题,正如上所述;同时预计这种应用范围将会被推广。 2.1.可以省略离线退火工序的冷镦钢用线材 另外一种新产品,可以省去离线退火工序的冷镦钢用线材,具有低的抗拉强度以及很好的韧性特点,它的特性相当于那些通过离线软化退火(700℃保温7小时)的传统

绿色建筑节能技术措施(最新)

绿色建筑节能技术措施(最新) 绿色环保理念已经深入人心,各行各业都在开展节能减排,降低生产活动对环境带来的损害。建筑行业在我国十分常见,建筑行业有着高能耗、高污染的特点,施工过程中,扬尘污染、噪音污染、固体废弃物污染等,给周围环境带来损害。绿色建筑的提出,将建筑同绿色环保理念进行融合,注重建筑建设中环保材料的使用以及新能源的应用,做到了建筑行业的节能减排。绿色建筑形式以及建筑节能技术的发展,对保护生态环境有着重要意义。 1绿色建筑的概念 所谓绿色建筑并非指屋顶花园、立体绿化等具体建筑形式,而是一种建筑理念,是指建筑物对自然无害,不破坏环境平衡,对自然资源合理利用的一种建筑形式。绿色建筑又可以称为节能环保建筑、生态建筑、可持续发展建筑等。绿色建筑与传统建筑不同之处有有:首先,传统建筑主要考虑建筑成本,忽略运营成本;绿色建筑使用全生命周期理论衡量建筑的成本,从建筑规划、设计、施工、运营、维护、拆除等各个环节,进行建筑成本的计算。其次,传统建筑对能源的消耗比较大,污染也比较大;绿色建筑可以有效地降低能耗和污染,为人们提供绿色、环保的节能空间。 2常见的建筑节能技术 2.1外墙保温技术

建筑节能设计中,外墙占据重要部分,外墙涉及到屋内屋外的能量转换,外墙保温技术是建筑技能的关键内容。外墙保温技术有以下作用:外墙保温技术可以保护主体构架,保证使用年限;避免建筑物出现“热桥”现象;避免墙体潮湿;保证室内温度的适宜;拓宽房屋使用面积。可以看出外墙保温技术,减少室内外能量的转换,实现了节能减排的目的。 2.2围护结构技术 屋顶、外墙、门窗、遮阳等是建筑的围护结构,对于建筑节能有着直接的影响,虽然围护结构占据建筑总投资费用不足5个百分点,但是通过节能技术可以实现40个百分点的节能。围护结构的节能技术,可以减少室内外的热量损耗。屋面节能方法:首先,屋面选择密度小且热导性差的材料;其次,保温层不能选择吸水性强的材料,否则会降低保温能力;最后,安装必要的排气孔,用于排除保温层的水分。窗户的节能设计:窗户是能量损耗的薄弱环境,通常情况下,单层玻璃有着较大的能量损失,可以达到50个百分点,窗户的隔热性是节能的关键。 2.3新能源的使用 建筑节能技术中,新能源的使用尤为关键。建筑设计中,融入新能源技术,可以有效地做到建筑节能减排的目的。新能源主要是指当前应用尚未广泛的一些可再生能源,例如,太阳能、风能、地热能、生物能等,虽然在部分区域这些新能源已经有着很好的应用,但尚未完全普及开来。以太阳能为例,太阳能的使用,对阳光的依赖性比较

建筑墙体的节能保温施工技术

建筑墙体的节能保温施工技术 温效果好的绝热材料和建筑的墙体融合固定为一体,使建筑墙体的热阻值变得更大更均衡,从而保持室内温度和热量的稳定,墙体保温技术的发展可以增强能源的利用率,降低能源的消耗量,采用科学合理灵活的设计方式,是一个集节能环保,保温隔热,安静隔音,美化装饰等各种功能于一体的墙体项目.。本文将从我国目前建筑的墙体保温技术现状研究开始,探讨我国墙体保温技术的发展状况,大力促进墙体保温技术的推广,同时为新技术,新材料的利用开发提出简单建议,从而使这项技术更好的服务于人民的生产生活。 关键词】建筑;墙体保温;节能环保;施工研究 中图分类号:TU111.4+1 文献标识码:A 文章编号: 引言 随着社会经济的快速发展,人民的生活水平显著提高,对建筑的要求也日益提高,建筑功能已经不仅仅限于以往的遮风挡雨,更倾向于多元化的,特殊化的需求,而保持室内气温的稳定,保持室内的热量稳定,则是其中一种多元化需求之一。面对居民这样的需求,建筑墙体的保温技术应运而生,它不仅是近些年国家大力支持鼓励的新型建筑节能技术在在我国的北方得到了广泛的推广和运用,更是当今社会新型建筑的一种新的建设突破,既美化了建筑外观,又可以降低能源消耗,较少能源的流失,同时也保障了居民室内生活环境的舒适,因此,墙体保温技术虽然在我国的发展起步较晚,但受到推广的力度很大,发展速度很快。

随着新的墙体保温技术的研发,新的墙体外保温适用材料较不断出现。目前常用的新型适合用于墙体保温技术的材料主要有聚苯乙烯泡沫板、岩棉板、酚醛泡沫板、各种复合保温浆料等表面涂抹纤维增强聚合物砂浆罩面材料。 二.新型保温材料选用和分析 1.建筑墙体保温节能材料的概述 建筑的墙体保温技术实施离不开各种保温材料的出现,根据不同的情况选择不同的保温材料,是进行墙体保温施工的基础。目前,出现的的保温材料种类繁多,包括泡沫塑料、矿物棉制品、泡沫玻璃、膨胀珍珠岩绝热制品、胶粉EPS颗粒保温浆料、矿物喷涂棉、发泡水泥等。 2.保温材料选用的原则 在我国,墙体保温施工选用的保温材料,也就是绝热材料种类和使用范围,需要符合GB/T17369-1998《建筑绝热材料的应用类型和基本要求》的规定。在选择运用施工时,首先是考虑保温材料的导热系数,一般使用的的保温材料的导热系数都不能超过0.2,其次,要综合考虑材料的燃烧性能,强度,和吸水率。据不同的材料特点,匹配将要施工的建筑。 在建筑建筑中选择合适的保温材料进行墙体保温技术施工,不仅可以舒适居民室内的生活工作环境,而且可以减少热量的流失,降低能源的消耗,提高能源的利用率,很大程度上降低污染,节约社会能源,缓解了能源压力。而对工业设备和特殊管道的保温,采用了合适的保温隔热措施,可以降低能耗,降低生产成本,同时可以帮助净化环境,

浅谈日本建筑文化 [摘要] 一直以来,日本文化善于吸收和包容外来文化,不仅继承了日本传统文化的内涵,而且在不断发展中与时俱进,从而形成了自己独特的文化,这种思想在建筑方面得到很好的体现,使日本建筑在世界建筑界享有声誉。看日本建筑,感受日本建筑文化。 [关键词]日本建筑;设计理念;建筑文化;传统;融合;内核;外缘 日本这个与中国有着一衣带水的特殊的地缘关系的民族有着尊重自然、单纯、质朴的文化精神,也正是因为这样,使得这个向来奉行拿来主义的民族对神社、寺院、住宅府邸、茶室甚至古堡等传统的建筑风格的创造有着根深蒂固的坚持。式和自然理念的一种坚持精神。我们知道文化创造的本质是发现、选择、吸收和创造,而且中日两国历史文化是源远流长的,不管是在幽静的小城还是在繁华的都市,不管是服饰、茶道、插花艺术还是建筑遗迹,我们都能从这些精致的细节当中感受似曾相似的文化底蕴。正因为日本与中国文化交流上的频繁,使日本在许多领域上的文化深受着中国的影响。建筑领域无不例外。然而,在对日本传统建筑的探析中所捕捉到的东西也让我们看到了日本民族吸收,包容外来文化的精华,是其恰到好处地融合于自身的地域文化,继而逐步创造出更富有时代意义及生命力的建筑的强大功力。透过日本建筑,看日本建筑文化,值得我们品味。 日本的设计理念:北欧人认为设计是他们生活的组成部分,美国人以之为赚钱的工具,日本人则认为设计是民族生存的手段。由于日本是一个岛国,自然资源相对贫乏,出口电器便成了它的重要经济来源。此时,设计的优劣直接关系到国家的经济命脉,以致日本设计受到政府的关注。日本的传统中有两个因素使它的设计没走弯路:一个是少而精的简约风格,另一个是在生活中他们形成了以榻榻米为标准的模数体系。在设计中,从国家、地区的实际情况出发,把民族审美理念同现代设计的某些因素结合起来,形成独特的设计体系,是设计的一个发展趋向。现代设计越来越认同本土化,本土化是对本土文化的认同,而不是对符号或图形的认同。探索本土文化的内涵,找出传统文化与自己个性的碰撞点,形成自己的设计风格,这才是设计本土化的精髓所在。日本的设计运用传统的理念,现代的元素和构成手法,走在了设计的前沿。 日本建筑中最有特色的是神社,遍布全国,约有十余万所,建造年代从古迄今从未中断。早期神社,模仿当时比较讲究的居住建筑,因为在观念上,神社是神灵的住宅,而人们只能按照自己的生活去揣摩神灵的生活,而且,建筑学当时也远远没有达到专为神灵别创一种神社型制的水平。因此,这些早期神社贴近朴实的人民生活,它们的建筑风格,可以代表日本建筑的基本气质。 当代建筑已进入了一个缤纷灿烂的多元化时代,现代技术文明赋予了建筑创作以广阔的天地。然而与此同时,建筑界开始重新审视决定建筑的主要因素——文化的内涵和影响其发展更新的因素。 建筑文化是指一个民族的历史、文化背景以及所属地区的地域特征等在群体或个体建成环境的反映。而此“文化”是由“内核”文化与“外缘”文化构成的。“内核”文化是指一种文化长期以来形成的本质的东西,它是古老的、纯种的、发育完善而自生根的文化;而外缘文化是新形成的文化,或对外来文化的吸收、

十大经典动漫

top1:龙珠(七龙珠) 日本的超人气动画,是日本著名漫画家鸟山明的得意作品。作为漫画,其世界销量3亿5000万册,位居第三。日本国内销量1亿5000万册,位居第二。该漫画后来被改编成动漫,无论是TV版还是剧场版,都吸引了无数的龙珠迷,掀起了一股股“龙珠”的热潮。而最后结局的那首《渐渐被你吸引》,更是让“珠迷”们感动不已,称其为永恒的经典一点也不为过! top2:灌篮高手 日本著名漫画家井上雄彦以高中篮球为题材的漫画及动画作品,其人物原型多为90年代风靡全球的NBA超级巨星。《灌篮高手》与《七龙珠》同为促成《周刊少年Jump》发行量跃居同类期刊之首的原动力,其经典之处甚至不下于龙珠! top3:圣斗士星矢 这部漫画不但风靡了全日本,还横扫中国大陆、台湾、香港等地区,占领了几乎所有的书店、报摊。1986年TV动画后在日本正式全国播出,中国中央电视台于1992年播放,造成中国大陆观众风靡一时的效果。其实,创作这部作品的灵感来自一份名为“狮子星座流星群”的资料,作者车田正美看到从天而降的流星,从而引发出圣斗士的概念。 top4:多啦A梦 作为一个常青的形象,伴随了几代少年儿童的成长。1969年,哆啦A梦首次被小学馆作为长篇连载漫画出版,自此,这个

可爱的机器猫就越来越受到广大观众的喜爱。当首部多啦A梦动画片于1979年在日本播出时,全日本随即掀起了哆啦A梦的热潮,尽管在早期的时候曾经有过几年萧条期,但是几十年来在日本取得了空前的成功。 top5:名侦探柯南 一部长盛不衰的作品,在本土和海外都有着极高的人气。作为国民动画的标志,柯南每年4月份黄金周上映的剧场版都能在当年票房榜上名列前茅,受到广大粉丝极大的期待。作者很善于埋线索,故事里的一些重大变化都有铺垫,令观众在推理讨论中得到很大乐趣。 top6:机动战士高达 自1979年登场以来,已成为日本机器人题材卡通作品中最著名、最经久不衰、最庞大的系列,与“宇宙战舰大和号”“新世纪福音战士EVA”并称为日本动画史上的三次高潮。《机动战士高达》系列之所以如此受人欢迎,最主要的因素在于从第一部作品中便体现出的复杂而有深度的悲剧性故事情节,这样不仅靠紧张刺激的机器人星际战争来吸引观众,而且对于追求内涵的迷家们,也有着充分的回味余地。 top7:变形金刚 1983年,擎天柱、大黄蜂等变形金刚玩具出现在各国的各大百货商店、超市、玩具店。而那时的少年们,每天都会盼着赶快放学回家,赶紧到晚上18:00点,因为那就能看《变形金刚》了。”
