Study on sea ice desalination technology

In winter in high-latitude oceans, there is a great amount of sea ice, which is being recognized as a new resource of fresh water. Different desalination methods including sea ice solid-state desalination and sea ice melt-water desalination were compared. In a centrifugal desalination experiment, rotation speed was one of the major controlling parameters. The best desalination result in terms of salinity was obtained at a rotational speed of 2000 rpm for a duration of 2-3 min. When sea ice was desalinated by slight-melting, environment temperature and time were the dominant factors. By using the reverse osmosis process, the total dissolved solids of sea ice melt-water could reach about 100 mg/L. The results indicate that methods of sea ice desalination could decrease sea ice salinity from 3‰-8‰ to 0.2‰-2‰ at a reasonable cost.

Indirect desalination of Red Sea water with forward osmosis and low pressure reverse osmosis

for water reuse

The use of energy still remains the main component of the costs ofdesalting water. Forward osmosis (FO) can help to reduce the costs of desalination, and extracting water from impaired sources can be beneficial in this regard. Experiments with FO membranes using a secondary wastewater effluent as a feed water and Red Sea water as a draw solution demonstrated that the technology is promising. FO coupled with low pressure reverse osmosis (LPRO) was implemented for indirect desalination. The system consumes only 50% (~1.5 kWh/m~3) of the energy used for high pressure seawater RO (SWRO) desalination (2.5-4 kWh/m~3), and produces a good quality water extracted from the impaired feed water. Fouling of the FO membranes was not a major issue during long-term experiments over 14 days. After 10 days of continuous FO operation, the initial flux declined by 28%. Cleaning the FO membranes with air scouring and clean water recovered the initial flux by 98.8%. A cost analysis revealed FO per se as viable technology. However, a minimum average FO flux of 10.5 L/m~2-h is needed to compete with water reuse using UF-LPRO, and 5.5

L/m~2-h is needed to recover and desalinate water at less cost than SWRO.

The role of functionalised multiwalled carbon nanotubes based supercapacitor for arsenic removal and desalination of sea water

In order to investigate the simultaneous adsorption property of functionalised multiwalled carbon nanotubes (MWNTs) for sodium and arsenic, a new type of carbon fabric supported functionalised MWNTs ( f-MWNTs) based supercapacitor was developed. In addition, this setup was tested for desalination of sea water. MWNTs were synthesised by chemical vapour deposition technique and purified, followed by functionalisation. MWNTs were characterised by different techniques. Performance of supercapacitor-based water filter was analysed for the adsorption of high concentration of arsenic (trivalent and pentavalent) and sodium as well as for desalination of sea water by using cyclic voltametry and inductively coupled plasma-optical emission spectroscopy techniques. Adsorption isotherms and kinetic characteristics were studied for the simultaneous removal of sodium and arsenic. High desalination (removal of sodium and magnesium) efficiency of sea water and cyclic repeatability for simultaneous removal of arsenic (arsenate and arsenite) and sodium have been demonstrated in this study. Easy handling and flexibility of this new type of electrodes-based setup provides a platform for the development of portable water filter.

如何查到英文文献全文

如何查到英文文献全文 1.如何进行文献检索 我是学自然科学的,平时确实需要不少外文文献,对于自然科学来讲英文文献检索首推Elsevier,Springer等。虽然这些数据库里面文献已经不算少了。但是有时还会碰到查不到的文献,而这些文献的数据库我们所在研究所或大学又没有买,怎么办?我基本通过以下向个途径来得到文献。 1.首先在Google 学术搜索里进行搜索,里面一般会搜出来你要找的文献,在Google学术搜索里通常情况会出现“每组几个”等字样,然后进入后,分别点击,里面的其中一个就有可能会下到全文,当然这只是碰运气,不是万能的,因为我常常碰到这种情况,所以也算是得到全文文献的一条途径吧。可以试一下。 2.如果上面的方法找不到全文,就把文章作者的名字或者文章的title在Google 里搜索(不是Google 学术搜索),用作者的名字来搜索,是因为我发现很多国外作者都喜欢把文章的全文(PDF)直接挂在网上,一般情况下他们会把自己的文章挂在自己的个人主页(home page)上,这样可能也是为了让别的研究者更加了解自己的学术领域,顺便推销自己吧。这样你就有可能下到你想要的文献的全文了。甚至可以下到那个作者相近的内容的其它文章。如果文献是由多个作者写的,第一作者查不到个人主页,就接上面的方法查第二作者,以此类推。用文章的title来搜索,是因为在国外有的网站上,例如有的国外大学的图书馆可能会把本校一年或近几年的学术成果的Publication的PDF全文献挂在网上,或者在这个大学的ftp上也有可能会有这样类似的全文.这样就很可能会免费下到你想要的全文了.

3.如果上面两个方法都没有查到你要的文献,那你就直接写邮件向作者要。一般情况下作者都喜欢把自己的文献给别人,因为他把这些文献给别人,也相当于在传播他自己的学术思想。下面是本人向老外作者要文献的一个常用的模板: Dear Professor ××× I am in ××× Institute of ×××, Chinese Academy of Sciences. I am writi ng to request your assistance. I searchone of your papers: 。。。。。。。。。。。。。。。。。(你的文献题目) but I can not read full-text content, would you mind sending your papers by E-mail? Thank you for your assistance. Best wishes !(or best regards) ××× 本人的经验是讲英语的国家的作者给文章的机率会大,一般你要就会给,其它不讲英语的国家,如德国,法国,日本等国家的作者可能不会给。出于礼貌,如果你要的文献作者E-mail给你了,千万别忘记回信致谢. 4.最后一种方法其实大家都熟悉,就是发贴在小木虫上求助。我还用另一种方法,就是直接让我所在的研究所图书馆的管理员帮我从外面的图书馆文献传递。不过有的文献可能是要钱的。一页0.3元,由于我们看文献的钱都是由课题出,所以也就不太考虑钱的问题了。

Housing Consumption and Economic Growth in China Wang XJ (Wang Xijun) School of Economics & Management, Weifang University of China, xjwang69@https://www.wendangku.net/doc/f518346417.html, Abstract: Consumption is a very important part in social reproduction, and its driving effect on social economic growth always plays the leading role. Housing is the basic living material which is essential for people?s life; housing consumption is the important material condition for the labor force reproduction. This study, based on China?s statistical data from 1985 to 2007,by employing co-integration theory, Granger causality test and error correction model (ECM),respectively investigates the relationship between consumption, housing consumption and economic growth. The empirical result denotes that there exists bilateral Granger causality relationship between consumption and economic growth. For a long period, there exists long term stable equilibrium relationship between GDP, consumption, and housing consumption; consumption and housing consumption both promote the growth of GDP. Housing consumption?s contribution to the growth of GDP is obviously higher than consumption. For a short period, consumption spurs the growth of GDP more than housing consumption. Keywords:Housing consumption; Economic growth; Co-integration ; ECM; Granger causality test I. INTRODUCTION Consumption is a very important part in social reproduction, and its driving

搜索英文文献的方法

如何搜索英文文献 【导读】 ①:正式发表的论文一般要进入大型的期刊论文数据库里检索; ②:搜索引擎更适合搜索普通的英文资料和论文检索入口。 一、哪里去搜索 1)图书馆 包括高校的图书馆、科研单位的图书馆、地方图书馆(如:国家图书馆、上海图书馆) 图书馆一般购买了大量的期刊论文数据库,供内部人员免费使用。 有中文为主的万方、维普,有外文的ProQuest、Springer 等。 注1:图书馆一般都提供文献代检服务,不过可能要收取一定费用。 注2:通过IP 代理的方式可以访问图书馆的这些数据库,不过是非法的。 2)利用在线期刊、论文数据库 国内的有: 中国知网:国家科技图书文献中心:万方

数据:或…… 国外的有:ScienceDirect:::…… 注:当然,除了国外的部分数据库有少量文献可以免费查看全文之外,都是要付费的。 这就需要登录这些数据库的帐号和密码,或者是代理IP。 3)利用搜索引擎 一般来说,英文的用Google 来搜索要好一点,因为它收录了大量国外的网站。 而百度主要针对国内的,如果你的话题是特别中国化的,那么百度也是不错的选择。 由于正式文档一般都采用pdf,要搜索pdf 文档,只需在关键词后,加个filetype:pdf 即可 除了以网页模式之外,还可以在Google 学术里或是百度文档里搜索,二者互为补充。 注:具体参见《搜索引擎常用技巧——英文资料篇》

4)利用免费文献网站 免费和收费是相对的,有些网站是全面免费,有些是部分免费, 而有些是等论文发表过了一定期限后才免费。 HighWire Press:::更多网站>> 5)向论文作者或网友求助 直接给论文作者发电子邮件,还是有一定机会得到回复的。 另外,有些作者会把自己的论文放在个人网站上。 至于网络求助,可以进入高校的论坛或者一些学术网站。 二、如何确定英文关键词 搜索英文资料的关键,还是要找到准确描述搜索内容的“英文关键词” 大家可以去这儿查: 1)知网翻译助手:(因为是根据论文内容来确定的,词汇或表达都比较准确)2)爱词霸:(金山词霸里有不少专业词典,网上的“百科词典”里的词条也有参考价值)

英文文献检索

文献检索是非常麻烦的事情,一般都是通过各种数据库进行检索,但由于购买的电子数据库基本都只有1997年以后的文献,文献量比较少,而且很多领域属于落后于国外20-30年的研究,一般很难查到,即使能查到出处,但无原文。文献查找是个费时费力的事情,需要细心和耐心,反复查找,以下谈谈个人关于如何利用网络进行文献查找的一些经验。 ①搜索引擎的高级功能 搜索引擎主要https://www.wendangku.net/doc/f518346417.html,和https://www.wendangku.net/doc/f518346417.html,,https://www.wendangku.net/doc/f518346417.html,则仅在检索中文时稍好点,英文很差,用处不大。我们常用的google侧重于网页的检索,Scholar则主要针对学术类文献进行检索,格式主要是pdf,对于论文的引用也会显示,对于知道文献名和作者的情况比较容易直接找到pdf文档,一般这两个搜索引擎要联合使用。 Google的高级检索功能中有几个常用的功能: (1)锁定关键词检索:使用双引号如”停车”,则所有检索结果均包含双引号中的内容,以减少检索结果量; (2)文件类型检索:文件类型主要是.pdf和.doc文档,国外文献大部分以pdf格式发布,使用格式限制可以排除很多不必要的检索结果,如输入:停车filetype:pdf,当然其它google 识别的格式都可使用; (3)指定网址检索:如果发现某个网站有需要的文献,则可以直接指定到该网站检索,以获得需要的资料,如输入:停车site:https://www.wendangku.net/doc/f518346417.html,。 Google的详细功能请参照google的高级检索,百度在使用上相同。 ②关键词的使用 检索结果如何,和关键词的使用直接相关,所以,首先要弄清楚在英文中关键词有哪几种表达方式,分别进行检索,而对于文献综述类,可以使用:review、overview、literature review、history、development、trend等和关键词一起检索。 关键词的检索并不是一次就能确定下来的,刚开始选用几个看能否找到,如果找到一些,先初步看看那些文献,对内容有了更深一些的认识后同时也对检索关键词增加了了解,实际上是不断调整检索关键词的过程 ③参考文献的使用 检索到一些文章后,先要看看文献后的参考文献,国外文献一般都会很详细的列出,可根据参考文献相应的进行有目的的检索,如找到指定数据库的期刊,或者检索作者,作者的个人主页一般提供作者本人发表文献的下载(最好的资源),有些还提供作者的E-mal,可直接写信给作者,一般对方都会提供。 另外,利用google的强大功能,对论文题名、期刊和作者进行检索,期刊的检索经常能发现该期刊被那个数据库收录,则可直接到相应的数据库找到,检索作者则最好加关键词、年等信息以缩小检索范围,而且不要用缩写,会忽略很多信息。 如果找到某个期刊历年的电子数据库,虽然网站有自己的检索功能,但最好不要检索之后其它就放弃了,实际上很多文献不一定检索得到,需要有耐心的一期一期的去看(当然实际上这个工作量并不大,国外的期刊一般每期也就10篇左右),但如果错过了需要的文献则损失

This article describes the development of railway electric power telecontrol system in China, analyzed the composition of railway electric power telecontrol system, exploring the main features of power telecontrol systems. (1)Overview of railway power telecontrol system in China Remote technology is widely used in China for long, but developed very rapidly, generally experience three stages in the development process: the contact point on the phase-phase, which is based on relays as the main component, supported by step selector switch, vacuum tubes and other components of the remote device. Remote device has a large number of such contact, maintenance, reliability, short life, an early remote products. Railway power supply without going through this phase. Second stage-routing logic stage, this stage through the transistor, integrated circuit process. Remote device is non-contact type of routing logic device, design according to requirements and constitute parts of the device logic circuits at a fixed time, to complete the intended function. These devices are hardware devices, not at liberty and expansion of functions. In the 70 's, the bulk power system in China has been using such devices, and there have been used on the electrified railway. Third-phase software phase, remote system of SCADA system in electrified railway in China on technology breakthroughs had been made, there are rapid application development. Because of electrified railway power systems have different characteristics, SCADA systems and power systems on the development of the road is not exactly the same. Due to the stable and reliable power systems are critical to the operation of the railway, in order to give full play to railway continuous power lines, closed lines (now General dutong called "through the wire"), ensure the safety of railway continuous power lines and reliable power supply, improve the management level of railway continuous power lines and control, reducing the impact on railway transport production, remote control technology in the 90 's were introduced in railway power systems in China. (2)composition of railway electric power telecontrol system 2.1 remote control master station Main stations generally use the computer network structure of remote control, distributed control systems, computer equipment for the core, to network nodes to be configured. System hardware configuration of the main front, back-end processing, maintenance operator network nodes such as node a workstation, analog screen man-machine interface device and corresponding device, set up real time data printing, document management report printers, peripherals such as monitors and satellite clock synchronization in real time.
