The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

In order to solve the problems from obtaining reservoir's formation pressure and injectivity index of each zone by conventional methods,combined with percolation theory and the characteristics for continuous measuring the data of flow,pressure in setting the water injection profile logging unit in one run,a new method is proposed for de.

针对常规方法获取分层吸水指数存在的问题，结合渗流理论和注水剖面测井一次下井能连续测量流量和压力的特点，提出了测井时多次改变井口注水量，通过注水剖面资料的处理确定各储层的相对吸水量、确定各储层的地层压力和吸水指数的方法，由此还能掌握各储层地层压力和吸水能力的差异。

Xie-Beni index decreases with the number of partitions increasing. It is difficult to choose the optimal partition of data when the number of clusters is large. From the point of view of the compactness and the separation of clustering, a novel clustering validity function is proposed, which is based on the improved Huber Г statistic combined with the separation of clustering.

针对此问题，分别考察改进的Hubert Г统计量和聚类分离度，导出一个新的基于数据几何结构的聚类有效性函数，使得它有惟一的最大值，函数值随聚类个数增大而递减的趋势并不影响最优聚类个数的判定。

The single and joint toxicity of perchloroethylene and 1, 4-dichlorobenze acting on grass carp was studied adopting the additive index method of the aquatic pollution-exposure experiment combined with joint effects of aquatic toxicology.

采用水生污染暴露试验和水生毒理联合效应相加指数法，研究了四氯乙烯和对二氯苯对草鱼的单一毒性与联合毒性。

So far, official pressure during the past couple of months -- combined with investor worries about slowing global growth and weaker corporate profits -- has produced the first prolonged pause in a bull run that saw the benchmark Shanghai Composite Index more than quintuple in two years.

迄今为止，过去几个月中政策面的压力，加之投资者对全球增长放缓和企业利润疲弱的担忧令中国股市的这一轮牛市首次出现长时间的调整。
