To reveal patterns of longitudinal distribution, seasonal variation, and ecological succession in cladocerans communities in the Three Gorges Reservoir, ten sites were used to sample cladoceran communities across a longitudinal gradient from April, 2004 to January, 2005. Nine cladoceran species were collected throughout the year.

中文摘要：为了阐明三峡水库初次蓄水后干流库区枝角类的时空分布规律， 2004年4月至2005年1月，在600余公里干流库区设置10个样点，定性和定量采集枝角类标本。

Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.

同时，由于Poisson分布的特性，我们知道不存在其参数区间长度小于0.5的置信区间，基于这些情况，我们主要展开了以下两个方面的研究：一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间，Wald置信区间，Bayes置信区间等进行分析比较，发现了一些缺陷，针对这些缺陷，我们进行适当的修正，并得到几种性质较好的置信区间如：修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度，我们提出了一种渐近的两阶段区间估计程序，并利用数值计算的方法，在各种置信系数与区间长度限定下，算出了最优的第一阶段观测次数，大量数据表明，本文考虑的方法性态良好，具有应用价值。

But under limited training sample size, increased dimension of remote sensing data means decreased samples/dimension ratio, which can lead to low classification accuracy if common statistic based pattern classification methods were used.

但在有限训练样本条件下，遥感数据维数的增高使样本/维数比率大大降低，采用常规的统计模式识别方法反而无法得到较好的分类结果。

New model utilizes grid computing technology,plans as a whole of network computing resources,combines with statistic classification advantage of support vector machine in finite sample space,probes into application of grid computation technology in image classification.

为了充分利用网格技术分布式、高性能、协同共享的能力，设计了一种基于网格和支持向量机的分布式图像分类器模型，采用网格计算技术，统筹网络运算资源，结合支持向量机在有限样本统计分类中的优势，探索网格技术在图像分类中的应用。

as a result of rapid development of city's industrialization in shanghai whereas the lag of industrial and domestic sewage's disposal and the building progess of city's cloaca,most of rivers was polluted badly.there are diversiform measures including biotechnologics for improving the water quality in shanghai.in this paper,the biotechnologic repairing's basic theory,effect,history,and application in the current world is expatiated.furthermore,a project sample which was put into practice in minghang district showed the feasibility and the actual effect of such technology in shanghai's water quality repairing.

由于上海市工业化和城市化的迅速发展，雨污分流与污水处理的建设和发展相对滞后，致使大量工业废水和生活污水直接排入河道，河道水质严重恶化。为改善上海河道水质，人们采取了多种措施，其中就包括采用生物技术修复河道水质的措施。本文浅要介绍了采用生物技术修复河道水质的原理、效果以及这种技术的发展简史、在国际上的应用现状，并以闵行区已经开展的邱泾河原位生物修复工程为例说明这种技术在上海市水质修复应用的可行性和实际效果。
