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。

Marc this paper carried out a finite element numerical simulation on the forming process of cold extruding for the starlike sleeve of constant speed cardan joint of car. The interrelated technological problems of numerical simulation were discussed in detail, the variation curve of extruding force during the course of loading, the cloud chart, which varies along with time, of temperature field distribution of workpiece, the equivalent plastic strain cloud chart of workpiece and the stress distribution cloud chart of diem inner ring were obtained thus explained fairly nice the reason of fatigue damage of dies.

RESULTS There were 10 species of all 118 strains of staphylococci,and the coagulase positive and negative rates were 43.2%and 56.8%, respectively. Staphylococci had high resistance to antimicrobial agents,especially MRSA and MRSE. The distribution of staphylococcal species varies in different diseases,and there was evident relationship between them.
