    In order to resolve the difficulties of the high-dimension numerical integral better, as for the productions whose life distribution belongs to exponential distribution, this paper brings forward the MCMC method based on Gibbs sampling to simulate dynamically the Markov Chain of the parameters' posterior distribution. It gives the parameters' Bayesian estimation of the exponential regression model in the condition of the random truncated test when the prior distribution of the failure rate belongs to the Normal distribution, and improves the precision of the numeration.

A linear system is described by a high order linear differential equation and it's the initial conditions, with Laplace transform for it obtained a transfer function of higher dimension. This paper presents a frequency simplification technique for simplifying a transfer function of higher dimension to a transfer function of lower dimension by the method of least squares.

一个线性系统是可以用高阶常系数线性微分方程及其初始条件来描述的。对它作拉普拉斯(Laplace)变换,得到一个高阶传递函数。本文意图对有意义的频率范围内的频率变量ω取n个水半ω_1,ω_2,…,ω_n,提供在最小二乘方的误差意义下有关高阶传递函数化简成低阶传递函数的一种频率域上简化方法。这种方法的最大优点在于对假定简化低阶传递函数的未知系数解的复杂工作大为简化,以期达到用标准计算程序来代替复杂而费时计算之目的。

A linear system is described by a high order linear differential equation and it's initial conditions. It has become a transfer function of higher dimension with Laplace transform. This paper presents a frequency simplification technique with stability constraint for simplifying a transfer function of higher dimension to a transfer function of lower dimension by the method of least squares.

本文作者曾经提供在最小二乘方的误差意义下有关高阶传递函数简化成低阶传递函数的一种频率域上的简化方法.曾经也通过具有纯滞后的一阶惯性环节(或二阶振荡环节),并借助Pade'近似式首先将具有纯滞后的传递函数简化;同时就以得到具有Pade'近似的一阶惯性环节(或二阶振荡环节)的低阶传递函数,而在最小二乘方的误差意义下作为有关高阶传递函数的近似式.不过,上述的简化低阶传递函数所描述的系统有可能是不稳定的.本文针对这个问题,提出在最小二乘方的误差的要求下还考虑稳定性约束条件.这样一来,将颁率域上模型简化问题转化成具有不等式约束的最优化问题.因此,就可借助罚函数法解决线性系统模型在频率域上简化问题,同时简化模型所描述的系统仍是稳定的.

This is a brief summary (from a theoretical view point) of the investigatomon the 'image of logical rpace'. The main content includes: (1) Mathematical analysis of the structural properties of n-dimensional logical space and that of n-element logical function. The one-to-one correspondence between this space and this function has been verified and the following principles were obtained: the set cardinal numbor of m-dimensional sub-space |α~m|=[n!/((n-m)!m!)]2~(n-m), the characteristic number of n-dimensional logical space also (2) Basing on the principlc of equality and using the method of 'm-dimensional set of the α-dimensional sub-image of k order' and the method of 'm-dimensional set of k order of the α-dimensional sub-image' a simplified image of a poly- dimensional logical space was obtained. (3) Analysis of the simplification of logical function gives the following two results: thus putting forward a general program of a simplified logical function: 'the isolated and non-recurring sub-spaces are taken one after another from f.This is done from low dimension to high dimension, in other words, it is done in the order of increasing number of dimensions until all the points are taken.'

本文是关于“逻辑空间图象”理论研究的一个小结.主要内容:1.从解析角度分析了n维逻辑空间及n元逻辑函数的结构性质,论证了二者之间的一一对应关系.其中,得到了m维子空间的集合的基数|α~m|=[n!/((n-m)!m!)]2~(n-m),n维逻辑空间的示性数X(P)=sum from K=0 to n(-1)~k|α~k|=1,以及|α~0|=|γ~0|=2~n,|α~m|=|γ~m|=[n!/((n-m)!m!)]2~(n-m)|α|=sum from m=0 to n|α~m|=|γ|=sum from m=0 to n|γ~m|=3~n等定理.2.根据等价原理,采用“k阶a维子图的m维集合”及“a维子图的k阶m维集合”两种方法,得到了简明的多维逻辑空间图象。3.分析了逻辑函数的化简,得到了二个结果.从而提出了一个化简逻辑函数的普遍程序:“由低维到高维,按次序地提取f中的不重复孤立子空间,直到提完所有的点为止”。
