Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30

One type of students are those who are short of study motion. This type of students can be divided into four situation. That is the contradiction between demands and realities, the repound after pressure, they have ever been defeated, they negate the value of study, Another type of students are those whose knowledge is not enough. Their previous knowledge can't catch up with the teaching demands of a vocational school. The third type of students are those who have no suitable study methods and good learning habits. The fourth type of students are the synthesis of all above.

其次从学生主观角度分析，其化学学习障碍产生的原因可分为四种类型：一是学习动力不足，这类学生又可大致分为四种情况，即需求的倒错、压力的反弹、心理曾经受挫和否定学习的价值；二是先备知识不足，表现在其先备知识与中专教学要求的不相称上；三是学习方法和习惯不好；四是综合体现上述三种原因。

Facing the fact that the inefficient china securities market, the article analyzes carefully the reason for low contract efficiency from the following aspects such as property rights, insufficient information regulation and the structure of regulation mechanism. What抯 more, the article points out reregulation is a possible way to normalization development of china security market after analyzing the disadvantages of strengthening regulation and deregulation. At length, the thesis paper will discuss the design of reregulation mechanism from the principles of incentive and constraint regulation institution and punishment mechanism.

面对中国证券市场管制低效的局面，本文从产权、信息不足约束以及管制机构治理结构等方面详细剖析了造成管制低效的原因，进而在分析加强管制和放松管制等论点的不足之后，指出再管制是通向中国证券市场规范化发展的可行之路，而且从管制机构激励约束、惩罚原则等方面讨论了再管制实施机制的设计问题。

Fortunately, the modern geodetic measurements such as the Global Positioning System technique can overcome the shortage of the geological and seismographic methods in the time dimension; and yet, the coverage of the geodetic survey stations is not sufficient. As a result, it is necessary to employ numerical simulation to investigate the continuous deformation of the crust.

而以全球定位系统等技术为主的大地测量方法弥补了地质和地震学方法在时间维上的不足，但大地测量方法存在测点覆盖不足及测点地理分布不均匀的缺点，因此，要得到连续的地壳形变场有必要借助数值模拟方法。

First, the erection of promote-gonad-hormone is not enough, or the erection of promote-gonad-hormone-release-hormone is not enough, or the erection of promote-gonad-hormone-resist-hormone is too sthenic, will influence the erection of sexual hormone.

首先，促性腺激素分泌不足，或促性腺激素释放激素分泌不足，或促性腺激素抑制激素分泌亢进，就会影响性激素的分泌。

As to cause serious shortage of electricity is the people and power system of consciousness, for example, the original building property within the sonic basic are now using light touch and original hand touch hands of the sonic, convenient, so rarely used, televox lights are always interference, virtually great waste power, but it still is used, then have a convenient and energy-saving?

至于导致电能严重不足的原因就是人们意识不足和用电系统的性能原始，比如说，楼道内的声控灯现在基本都还采用原来的手触和声控的，手触的不方便，所以很少被采用了，声控灯总被干扰，在无形中极大的浪费了电源，但是现在依然被采用着，那么有没有一种既方便又节能的呢？

至于导致电能厉害不足的缘故就是人们意识不足和用电系统的性能原始，比如说，楼道内的声控灯现在基本都还采用原来的手触和声控的，手触的不方便，所以非常少被采用了，声控灯总被干扰，在无形中极大的浪费了电源，但是现在依然被采用着，哪么有没有一种既方便又节能的秦？

Chromatic plastic film and light conversion film has been applied in protected cultivation, and plastic films with different light quality may serve as a non-chemical approach regulating growth and thermoperiodic responses of plants. A few studies showed that light quality affected growth and yield of strawberry, but little is known about its effects on photosynthesis and chlorophyll fluorescence in strawberry leaves, and fruit quality. So it is beneficial to scientific regulating growth and fruiting for strawberry protected cultivation to study on those effects and the interactions between CO2 and N supply on photosynthesis.

而低氮影响植株生长、叶片黄化，进而影响光合作用，导致抗性减弱和产量品质下降；③CO_2供应问题：目前我国草莓栽培常在设施环境下进行，在封闭性强的设施中空气流通不畅，常导致设施内部CO_2供应不足而影响光合作用，进而影响产量和品质；④光不足与光质问题：设施栽培中，光通过玻璃和塑料棚膜后使设施内的光强与光质均发生改变，这些变化特别是光质变化对草莓生长与结果的影响程度尚无明确认识。

Respondents also expressed a shortage of funds(71.2%), manpower(50.2%) and residents' uncompliance(43.7%) which were the main reasons obstructed community environmental health tasks.

而受访者也表示经费不足(71.2%)、人力不足(50.2%)及居民不愿意配合(43.7%)，是阻碍其推行社区环境卫生工作的主要原因。
