Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

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。
