PART 2 PRODUCTS

2.1 IDENTIFICATION PLATES

Provide manufacturer installed identification plates of non-corrosive metal showing, in clearly legible permanent lettering, the manufacturer's name, model number, capacity rating in pounds, and other essential information.

Also provide monorail track beam identification plates showing the capacity of the system, in pounds, legible from the floor and from either side of the monorail track beam.

2.2 OVERHEAD MONORAIL SYSTEM

************************************************************************** NOTE: Plain type (hand operated) trolleys are

recommended where trolley motion is infrequent or

the distance is short, providing good load spotting ability and use for hoists of 3 metric ton (3 ton) capacity and under. Plain type trolleys are not recommended for hoists of 3 metric ton (3 ton) capacity and greater, or for tracks higher than 6 m (20 feet) above the floor level. Motor operated trolleys are recommended where the operating frequency, travel distance, rated load, or beam elevation makes other types of trolleys impractical. This specification is written for a single monorail system and hoist. Edit the following paragraphs to reflect number, types, capacities of monorail track systems, hoists, trolleys, etc.

Off the shelf monorail systems consist of MH27.1 Patented Track Systems and MH27.2 Enclosed Track Systems. MH27.1 systems feature exposed running flanges and trolley wheels and systems can have equivalent center loads in excess of 150 tons.

MH27.2 systems feature enclosed running surfaces where trolley wheels are fully covered by the track and systems have rated capacities typically less

than 4000 lbs

When there is one hoist on one monorail system, the monorail system capacity and the hoist capacity must be compatible. When there is more than one hoist on the monorail system, the capacity of the monorail system must be capable of carrying the total sum of the system hoists individual rated capacity with the following exception:

1. There are positive monorail track beam stops to restrict the approach of the hoists.

2. Calculations indicate that at the point of

closest approach of the hoists, with rated capacity load on the hoists, the monorail track beam and monorail support points (and appurtenances) are not loaded in excess of the load condition imposed by any one hoist with rated load in any location.

Should conditions 1 and 2 exist, then the capacity

of the monorail system must be equal to the capacity of the highest rated individual hoist in the

monorail track system. Do not specify a monorail system of greater capacity than required as this

will increase the system cost.

Unless otherwise specified, the nominal rated maximum speed of the hoists and trolley will be the manufacturer's standard within the limits of Table 2 of ASME HST-1, HST-4, HST-5, HST-6, AS APPLICABLE. For higher tonnage ratings, consult with the manufacturer(s).

Do not specify a longer lift range than required as

this will increase the building height and hoist

cost.

************************************************************************** Provide overhead monorail system conforming to [MHI MH27.1, Duty Class C][ MHI MH27.2, Frequent Usage (Heavy Service)], for [indoor][outdoor] service, with [an electrical chain hoist][a hand operated chain hoist][a lever

地理规律性常识

地理规律性常识 一、地球运动部分 1、地球自转线速度变化规律——赤道最快(111*15千米/小时),向两极递减。南北纬60°相当于赤 道的一半(111/2*15千米/小时);两极点线速度为0。 地球自转角速度——除两极点外全球相等。(约15°/小时) 2、地球公转的线速度变化规律——近日点(1月初)最快,远日点(7月初)最慢。从近日点向远日 点逐渐变慢;从远日点向近日点逐渐加快。(角速度,同样规律)3、经纬度数值变化规律——东经度向东(即自转方向)增大,西经度向西(即逆自转方向)增大; 北极上空看是东经度呈逆时针方向增大,西经度呈顺时针方向增大; 北纬向北增大,南纬向南增大。 4、经纬度距离变化规律——纬度差1°南北实际距离差约111千米; 经度差1°东西实际距离从赤道向两极缩短(赤道上约111千米,向极地呈余弦函数递减(即111*COS纬度) 5、昼夜长短变化规律—— 空间规律①太阳直射哪个半球则该半球昼长夜短,反之,昼短夜长。 且越往高纬走,长者越长,短者越短。 ②同纬度地区山上日出比山下早、日落时间比山下晚即山上昼长多于山下 时间规律①太阳直射点向哪个方向移动,该半球就昼渐长夜渐短,反之昼渐短夜渐长 极昼极夜分布规律——从春分到夏至到秋分(北半球夏半年),北极地区极昼范围逐渐扩大再逐渐缩小;从秋分到冬至再到次年春分(北半球冬半年),北极地区极夜范围逐 渐扩大再逐渐缩小。南极地区相反 6、昼夜长短的季节变化——无论南北半球,其夏半年始终昼长夜短,冬半年昼短夜长。而且 同一半球纬度越高,长者越长,短者越短。 夏至和冬至分别是最长和最短的时间点。也是太阳直射点南北回归运动的到达最北界和最南界的时间 7、晨昏线的相关规律性知识—— ①晨昏线的移动方向和地球自转方向相反,始终自东向西移动。每小时15度 ②晨线和赤道的交点所在经度上的地方时刻为6点,昏线与赤道交点处的经线上地方时刻为18 点; 只有春分和秋分两天全球日出时间都为6点,日落时间为18点 ③春秋分日晨昏线和经线重合,且过极点,全球昼夜等分。 晨昏圈和极圈相切,北极附近为极昼则是夏半年,切点所在经线上的地方时为0点;若北极附近为极夜,则是冬至日,切点所在经度地方时为12点,南半球依此类推。 ④晨昏线与经线的夹角度数等于太阳直射点所在的纬度数值,这个度数与晨昏圈和纬线圈的切点所 在纬度互为余角。 光照图上隐含时间:“晨赤交6、昏赤交18、切昼为0、切夜为12” 8、太阳直射点的回归运动 ①太阳直射点所在纬度的正午太阳高度为最大——90°。 从直射纬度向南北两侧方向递减。纬度与直射点的纬度差一度,正午太阳高度就减小一度。(见计算公式)而同一地点,正午12点太阳高度最大,早晚日出日落时为0,半夜0点太阳高度最小。 ②北回归线以北地区,一年中夏至日正午太阳高度最大,冬至日最小。南回归线以南地区相反 ③一年中,正午太阳高度越大,物体的影子越短,反之则越长;一天之中,正午12点时太阳高度最 大,物体影子最短,早晚影子最长(可以达到无限长)

生活中五种常见疾病的高发时段提醒

生活中五种常见疾病的高发时段提醒 生活中很多常见病在发病时间上都有规律,通过数字进行归纳,便于大家记忆。 肝病:每年的4~7月,是肝功能不良患病的高风险期,此时外界细菌、病毒滋生较多,会增加肝的解毒负担。临床检测发现,肝细胞恶变及其恶性生长的活跃期也在这一时间段。肝病发作前一般会出现食欲不振、肝部隐痛、易怒、易疲劳等症状。中老年朋友若出现上述症状,应及时到医院检查。 防治措施:可常食鲫鱼(有助于消肿、补虚保肝)、猕猴桃(富含维生素C,可提高肝脏酶的活性,强化分解排泄功能),还可多吃点裙带菜(其中含有岩藻低聚糖,能抑制肝的病变)。 胃溃疡:每天19~24点,是胃酸分泌最多的时段,胃溃疡患者的胃部疼痛会加重。在此时段常有烧心、泛酸、胃部不适感的中老年朋友,应警惕胃溃疡。 防治措施:胃酸多者的早、午餐宜多食西兰花、豌豆、莴苣、核桃、花生、小麦等富含胡萝卜素和B族维生素的食物,因为每天7~13点是胃黏膜不易受到胃酸侵害的时段。晚餐宜选用土豆、南瓜、冬瓜、猴头菇、茄子等炖软食物,也可食用富含维生素E的鲜鱼,以抑制夜晚胃酸的分泌;要注意,晚餐不可食用芹菜、韭菜、泡菜、竹笋、豆芽、火腿、鱼干等,它们会增加胃酸的分泌;晚上尽量10点前入睡,睡觉越晚胃酸分泌越多。 糖尿病:每天上午7~9点,是一天中血糖水平最高时段,容易加重动脉硬化、白内障、老花眼。 防治措施:血糖较高的中老年朋友早餐不宜喝稀饭。因为,稀饭加热时间较长,淀粉易转化为糊精分解为葡萄糖,喝稀饭会使血糖水平升高。可喝燕麦薏米粥或牛奶、豆浆,并搭配鸡蛋、玉米饼等食物,以延缓血糖上升。早餐要少吃咸菜等高盐食品,盐会增强淀粉酶活性,引起血糖浓度增高。 肺病:每天凌晨0~4点,肺部防御功能最弱,是肺部发病和病情加重的时段,哮喘、肺部不适并伴有气喘、头晕、乏力的中老年朋友,应警惕这段危险期。 防治措施:晚餐宜进食清淡、易消化的食物,多吃果蔬;晚间选择令人舒心的电视节目,避免焦虑、恐惧、忧郁;睡前喝杯白开水,有助于防止夜间肺病发作;应采取侧卧睡姿,降低气管呼吸阻力,并注重夜间保暖。 心血管病:每天9~14点,是人体心率、血压、房室传导功能的最高峰,容易诱发“器质性”室性心律失常、心肌缺血、心肌梗死等心血管疾病。这一时间段常头晕、耳鸣或运动后心慌、胸

口蹄疫发生的周期性规律

口蹄疫俗称为“五号病”
当有人问什么是 “五号病” 只能告诉: 时, 口蹄疫是一种严重危害偶蹄类动物 (牛、 羊和猪)的疾病。对于危害不严重的年份,蹄子往往不出现水泡,只有口鼻处出 现水泡,此时就只能称为“一号病” ;当疾病严重发生的时候,这些动物的蹄子 和口鼻处均会出现水泡, 口和四个蹄子等五个部位都出现水泡, 就称为 “五号病” , 五号病是口蹄疫中最严重的类型。五号病也是一种需要保密的疾病。 当世界某地的大量牲畜被宰杀的时候, 位于地球上的许多贫困地区的饥饿却在日 益加重, 花样繁多且日趋严格的法律法规和行政干预措施的有效性也成了争议的 焦点。那么,口蹄疫的未来之路在哪里?兽药招商 1、口蹄疫是一种很小的病毒,易通过空气传播,动物出现临床表现的差异也很 大。当一栋猪舍出现口蹄疫的少量病例时,其它动物已经感染,此时消毒已经无 济于事。 猪场管理者在猪舍内大量消毒只能造成空气的过度潮湿, 消毒一旦停止, 病毒气溶胶会重新出现在更加潮湿的空气中,更利于疾病的传播。兽药批发 2、灭活疫苗的不完全灭活是口蹄疫疫苗中的最大问题。如果加上口蹄疫灭活疫 苗的无效性或弱效*,接种该疫苗的风险要大于不接种的风险。欧洲数次发生口 蹄疫均已证实与疫苗接种有关。对于现行猪场来说,就成了仁者见仁、智者见智 的问题了。 为什么灭活疫苗有时候有保护作用, 有时候又没有保护作用呢?病毒变异了吗? 推论:疫苗的半灭活状态或许是疫苗有效性的可靠保证,有待进一步论证。若真 的是这样,灭活疫苗带毒反而却成了疫苗有效性的保证了。 在疫苗的生产中,安全性和有效性往往是一对矛盾。其中,口蹄疫中的肽疫苗就 是一个明显的例子。合成肽疫苗对多种靶动物都不像预期的那样有效。当合成肽

形的骨架大致成网格状排列。特别是在我国东部,三列东西走向的山脉,同三列东北—西南走向的山脉相互交 织成网格状,沿着这些走向的山脉,两侧有相对低洼的地区,亦大致成网格状分布。其二,在世界陆地上,有 两个巨大的高山带,一是环太平洋高山带,它包括南、北美洲的科迪勒拉山系。澳大利亚大分水岭以及亚洲东 部岛弧上的山脉,纵列分布在太平洋东西两岸,二是亚欧大陆南部高山带、包括喜马拉雅山脉、高加索山脉、 阿尔卑斯山脉等,多呈东西走向。这两个高山带在帕米尔高原集结;阿尔卑斯山系又以阿尔卑斯山为其山结。 其三,是海底地形,大致可分为大陆架、大陆坡和海底三部分。洋底中部都有一条海底山脉即海岭,两侧分布 着一系列海盆,在大洋边缘有狭长深邃的海沟。 三、地理分析规律。所说的地理分析,即通过地理思维活动,

将个别的、局部的、分散而具体的地理事物 ,按其内在联系。进行归纳、总结、综合,从而得出概括性的结论。通过地理事物的分析、突出特征、阐明共 性、揭示规律。这对于发展学生智能、明确地理概念和知识结构、全面而系统地掌握知识极为有益。那么分析 地理事物应从哪些方面入手呢? 其一,自然特点的分析。所谓的自然特点,泛指一个地区的地理位置、地形、气候、河流、自然资源等地 理要素,是一个综合概念。分析各个要素时,应从它们的属性、内容和知识系统等方面考虑。例如,地理位置 一般从纬度位置、海陆位置、相关位置和交通位置等方面进行分析;地形特征从地势、地形类型、地形分布、 地表特征和特殊地形等方面进行分析;气候一般从影响因素、主要组成要素上分析说明其特征,气候类型,水 热状况、季节分配、年际变化,特殊天气现象等;河流的水文特征从流量、汛期长短,水位变化、含沙量、有

疾病发病情况的时间序列分析

某市恶性疾病的时间序列分析 摘要:本文对某市1990~2007年间某恶性疾病的发病情况进行统计,运用时间序列分析,建立ARIMA模型对该病发病情况进行研究,并对未来几年的发病情况做出了预测。 关键字:时间序列ARIMA,拖尾截尾 时间序列分析的简介 时间序列分析(Time series analysis)是一种动态数据处理的统计方法。该方法基于随机过程理论和数理统计学方法,研究随机数据序列所遵从的统计规律,以用于解决实际问题。 时间序列是把反映现象发展水平的统计指标数值,按照时间先后顺序排列起来所形成的一组统计数字序列。时间序列又称动态数列或时间数列。时间序列分析就是利用这组数列,应用数理统计方法加以处理,以预测未来事物的发展。时间序列分析是定量预测方法之一,它的基本原理:一是承认事物发展的延续性。应用过去数据,就能推测事物的发展趋势。二是考虑到事物发展的随机性。任何事物发展都可能受偶然因素影响,为此要利用统计分析中加权平均法对历史数据进行处理。该方法简单易行,便于掌握,但准确性差,一般只适用于短期预测。时间序列预测一般反映三种实际变化规律:趋势变化、周期性变化、随机性变化。 时间序列分析是根据系统观测得到的时间序列数据,通过曲线拟合和参数估计来建立数学模型的理论和方法。时间序列分析常用在国

民经济宏观控制、区域综合发展规划、企业经营管理、市场潜量预测、气象预报、水文预报、地震前兆预报、农作物病虫灾害预报、环境污染控制、生态平衡、天文学和海洋学等方面。 时间序列分析主要用途:①系统描述。根据对系统进行观测得到的时间序列数据,用曲线拟合方法对系统进行客观的描述。②系统分析。当观测值取自两个以上变量时,可用一个时间序列中的变化去说明另一个时间序列中的变化,从而深入了解给定时间序列产生的机理。 ③预测未来。一般用ARMA模型拟合时间序列,预测该时间序列未来值。④决策和控制。根据时间序列模型可调整输入变量使系统发展过程保持在目标值上,即预测到过程要偏离目标时便可进行必要的控制。 基本步骤:①用观测、调查、统计、抽样等方法取得被观测系统时间序列动态数据。②根据动态数据作相关图,进行相关分析,求自相关函数。相关图能显示出变化的趋势和周期,并能发现跳点和拐点。跳点是指与其他数据不一致的观测值。如果跳点是正确的观测值,在建模时应考虑进去,如果是反常现象,则应把跳点调整到期望值。拐点则是指时间序列从上升趋势突然变为下降趋势的点。如果存在拐点,则在建模时必须用不同的模型去分段拟合该时间序列,例如采用门限回归模型。③辨识合适的随机模型,进行曲线拟合,即用通用随机模型去拟合时间序列的观测数据。对于短的或简单的时间序列,可用趋势模型和季节模型加上误差来进行拟合。对于平稳时间序列,可用通用ARMA模型(自回归滑动平均模型)及其特殊情况的自回归模型、

高一地理必修一《自然地理环境的差异性》知识点总结

高一地理必修一《自然地理环境的差异性》 知识点总结 高一地理必修一《自然地理环境的差异性》知识点总结【考纲】 1.识记自然带的概念、名称与分布规律。 2.理解水平地域分异规律与垂直地域分异规律的成 因。 3.学会分析陆地自然带与世界气候类型的相关性。 【知识点】 一、地理环境的地域差异 1.表现:地理环境各组成要素及其组合上的差异。 2.成因:不同地域物质、能量分布的不同状况。 3.自然带的形成(带状)。 自然地理环境的差异性 二、地理环境地域分异规律的地域分异 1.水平地域分异 (1)由赤道到两极 影响因素:太阳辐射 形成基础:热量 分布规律:大致与纬线平行,沿东西方向延伸,南 北方向更替 (2)从沿海向内陆的地域分异方向延伸

影响因素:降水 形成基础:水分 分布规律:平行于海岸方向延伸,垂直于海岸方向 更替 2.垂直地域分异 规律:地表景观随高度发生有规律的更替现象,纬 度越低,,山体越高,自然带越丰富, 成因:主要是山地随海拔的增加,水分条件、热量 状况及其, 组合的垂直变化)) 3.非地带性分异规律:主要受海陆分布、地形起伏、洋流等因素的影响。 【问题思考】 1.在地球表面的自然地理环境中能否找到两个自然状况完全相同的区域?为什么? 答案:不能。因为不同区域物质、能量分布及其组 合状况是不同的,地域差异在自然地理环境中是普遍存 在的。 2.想一想:是不是任何一个山地都具有垂直地域分异规律?为什么? 答案:并不是所有的山地都具有垂直地域分异规律。只有山地达到一定高度,并在一定的纬度范围内,足以 引起自然环境及其组成成分的急剧变化以后,才有可能

出现。因此山地自然带的发育往往与该山地所处纬度及相对高度有关。 3.赤道附近的东非高原为什么会呈现出热带稀树草原景观? 答案:东非高原海拔高、气温低、降水少,不具备形成热带雨林的水热条件。

(2)一种要素的变化往往会引起其他要素的系列变化,进而导致地理环境整体发生变化。 地理环境的地域差异性表现为: (1)不同地区各地理要素具有不同的特征,各地理要素之间相互作用相互影响,形成千差万别的地理环境; (2)人类在利用、建设环境时,必须因地制宜、对具体事物进行具体分析。 6、自然地理环境的区域差异主要有地带性规律和非地带性分异。 7、地带性规律又分为纬度地带性、从沿海到内陆的地带性和垂直地带性等基本规律。 【知识点二】:专题2、纬度地带性(表现、成因、对社会经济的影响) 【学习要求】: ④理解由赤道向两极的自然带分布规律及其主导因素 ⑩比较不同自然带的特征,分析成因 ?结合实例分析自然地理环境的地域分异规律对社会经济的影响 【知识梳理】 1、纬度地带性是地理环境及组成要素具有按纬度变化方向发生变化,沿纬线方向延伸成带状分布的特征,主要表现为:气候、土壤、生物及其环境,从赤道向极地有规律的更替。 2、自然环境的纬度地带性以热量为基础。 3、气温从低纬到高纬逐渐降低,从赤道至极地分为热带、亚热带、温带、亚寒带、寒带等不同温度带。 4、在热量分配和水分共同作用,自然景观沿纬度变化方向发生有规律的更替和变化,在低纬地区和北半球高纬地区较典型。 5、自然带通常指主要受地带性分异因素影响,在地表沿一定方向大致呈带状延伸分布,并具有一定宽度的自然区划单位。 6、陆地自然带的存在是地理环境差异性的体现,是各地环境要素相互作用的结果。 7、以植被类型为标志,划分世界陆地自然带,具体分布图见课本P6 图1.3(牢记),(各自然带特征见课本P6-P8)。 8、自然带的形成是以热量和水分为基础的,因此,自然带的分布基本上与气候类型分布一致。 9、土壤的纬度地带性特征(见课本P9)。 10、纬度地带性的成因:是由于地球的球体形状造成太阳辐射在地表分布不均所致。 2

高考地理知识点分类归纳

高考地理知识点分类归纳 第一类、地理计算类: 时差、正午太阳高度、日照长短;比例尺;温差、海拔高差等常需计算来解决问题。 1、依据概念、公式、方法、技巧等,采集相关的数据来分析。 如:地方时差的计算:时刻东早西晚(自然),从时间日期看自180°向西愈西愈晚(人为规定)。 正午太阳高度:H=900-φ±δ(ф为某地纬度,δ为直射点纬度,夏半年取+,半年取-) 日照度长短中:日出时刻=12-昼长/2=夜长/2。 比例尺或经纬网图中的计算,常用?110千米/1°(沿经圈或赤道上)?; 温差、海拔高差中?6℃/1000米?(气温直减率)等是十分重要的计算依据。 2、采取统计图表中的极端数值,或依概念性规律采集数据信息,利用要素的关联性进行推理分析。 第二类、分析区域环境区位特点、优势及评价: 1、分析区域的地理环境特点:从区域的环境要素结构因子出发,通过综合、比较分析,比较中往往是与同纬度(东西)比较为主,也有同经度(南北)比较两个度,比较是为了突出该区域的地理环境的特殊性,?人无我有,人有我优?的特点,分析的目的是为发挥比较优势,以便因地制宜地找出区域科学发展之路。如:北京与巴黎的气候相比,其特点是夏热冬冷,年气温较差大,降水集中于夏季;雨热同期,利于农作物生长;水旱灾害较多。北京与广州气候相比年温差较大,雨季较短,降水集中于夏季7、8月,表现为大陆性较强。 2、分析区域的经济区位优势特点。 第三类、地理可持续发展,树立科学发展观类 围绕人口、资源、环境和发展这一主线,回答促进人地关系的协调的措施,树立可持续的、科学的发展观,应注意?地理是将来进行式?,答题的方向是: 1、?问题地理?是地理特色,围绕人口、资源、环境和发展这一主线,地理试题主要是考地理环境中的问题的表现、成因、对策的理解,应体现地理科学对国情资源的忧患意识。提高的资源忧患意识和节约意识,树立节约资源的观念,培育节约资源的风尚,提倡绿色消费。围绕主题说危机,谈不足,论缺陷;找原因、出对策。 如:我国黄土高原存在的生态问题有哪些?——人口压力大,土地负载重;毁林开慌,过度放牧,水土流失严重,地表破碎,千沟万壑;地处自然地理的过渡地带,旱涝灾害,地质灾害多发;生活贫困。 同理,①、西北的地理主题往往是荒漠化、盐碱化问题;

107个公基常考地理知识点汇总

1.洋流按冷暖性质分:洋流按其水温低于或高于所流经的海域的水温,可分为寒流和暖流。 ▎2.暖流:从水温高的海区流向水温低的海区。 ▎3.寒流:从水温低的海区流向水温高的海区。 ▎4.洋流按成因分类:洋流按成因分类:洋流按成因分为风海流、密度流和补偿流。 ▎5.风海流:在风力作用下形成的洋流。盛行风是海洋水体运动的主要动力。盛行风吹拂海面,推动海水随风漂流,并且使上层海水带动下层海水流动,形成规模很大的洋流,叫做风 海流。世界上大洋表层的海洋系统,按其成因来说,大多属于风海流。 ▎6.密度流:在密度差异作用下引起。不同海域海水温度和盐度的不同会使海水密度产生差异,从而引起海水水位的差异,在海水密度不同的两个海域之间便产生了海面的倾斜,造成 海水的流动,这样形成的洋流称为密度流。 ▎7.补偿流:因为海水挤压或分散而引起的洋流。当某一海区的海水减少时,相邻海区的海 水便来补充,这样形成的洋流称为补偿流。补偿流既可以水平流动,也可以垂直流动,垂直 补偿流又可以分为上升流和下降流,如秘鲁寒流属于上升补偿流。 ▎8.洋流分布规律一:中低纬度海域形成以副热带海域为中心的大洋环流,北半球呈顺时针 方向运动,南半球呈逆时针方向运动。 ▎9.洋流分布规律二:北半球中高纬海域形成以副极地海域为中心的逆时针方向运动的大洋 环流。 ▎10.洋流分布规律三:南半球40°附近海域形成环绕全球的西风漂流,性质为寒流。 ▎11.洋流分布规律四:北印度洋海域形成典型的季风洋流,夏季洋流呈顺时针方向流动,冬 季洋流呈逆时针方向流动。 ▎12.洋流对气候的影响:暖流对沿岸气候有增温增湿作用;寒流对沿岸气候有降温减湿作用。 ▎13.洋流对海洋生物的影响:寒暖流交汇的海区,海水受到扰动,可以将下层营养盐类带到 表层,有利于浮游生物大量繁殖,为鱼类提供饵料;两种洋流汇合还可以形成“水障”,阻碍 鱼类游动,使得鱼群集中,易于形成大的渔场。比如在秘鲁附近海区,受离岸的东南信风影响,深层海水上涌把大量的营养物质带到表层,形成了著名的秘鲁渔场。
