yang xiangqun

The characteristic numbers and their probability meaning of the birth and death process have been settled by both professor yang in [ 1 ] and professor wang in [ 2 ]
杨向群教授在文献[ 1 ] ，王梓坤教授在文献[ 2 ]中，对以0为反射壁的生灭过程的特征数及其概率意义已解决。
The characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier have been partially settled by professor yang in [ 1 ] , which depends on setting up a method that solving system of liner equations with two boundaries . in this thesis , the author has setted up another method that solving system of liner equations with one boundary on the basis of the former method , and has improved further the characteristic numbers and their probability meaning of the birth and death process with zero as its quasi - leap - reflecting barrier
在文献[ 1 ]中，杨向群教授创立了解含两个边界的线性方程组的方法，并利用该方法对对以0为拟飞射壁的生灭过程的特征数及其概率意义有了部分解决。本文是在此方法的基础上创立了解含一个边界的线性方程组的方法，并利用这两种方法对以0为反射壁和拟飞射壁的生灭过程的特征数及其概率意义做了进一步的完善。
