  1. 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 as are 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

    同時,由於poisson分佈的特性,我們知道不存在其參數區間長度小於0 . 5的置信區間,基於這些情況,我們主要展開了以下兩個方面的研究:一是利用數值計算分析與理論分析的方法對現有的若干置信區間如「精確」置信區間, wald置信區間, bayes置信區間等進行分析比較,發現了一些缺陷,針對這些缺陷,我們進行適當的修正,並得到幾種性質較好的置信區間如:修正大樣本區間jeffreys原則下置信區間二是針對已給定的置信系數與區間長度,我們提出了一種漸近的兩階段區間估計程序,並利用數值計算的方法,在各種置信系數與區間長度限定下,算出了最優的第一階段觀測次數(抽樣量) ,大量數據表明,本文考慮的方法性態良好,具有應用價值。

  3. It is necessary to control the mechanical stimuli precisely in the studies of cardiac mechano - electrical feedback ( mef ). in the present study a ventricular pressure - clamping system has been developed, which can be applied to isolated - perfused rabbit hearts. controlled by a computer, this system not only can make the left ventricle follow a command defining the same pressure wave as that during a beating cycle under physiological condition, but also deliver mechanical stimuli with a proper waveform to the ventricle at a particular time phase. this system integrates multiple functions, including perfusing, pacing, recording of electrocardiogram and monophasic action potentials, and clamping and measuring of ventricular pressures in isolated - perfused hearts. thus, it is a distinct system for investigating the phenomena and mechanisms of cardiac mef at organ level

    在心臟機械電反饋的研究中準確控制機械刺激是非常重要的.本研究室構建了一套適用於離體家兔心臟的心室壓力鉗系統.該系統通過計算機控制壓力鉗,不僅能模擬正常生理條件下左心室的壓力波形,還能在心室活動周期的特定時相、以適當波形對心室施加機械刺激.該系統集心臟灌流與起搏、表面心電圖記錄、單相動作電位記錄、心室壓力鉗制與測定等多種功能於一體,特別適用於器官水平上觀察機械電反饋現象並探討其機制
