| 摘 要： | 利用特征函数研究了服从二项分布和正态分布下的随机变量的再生性问题,即相互独立的随机变量之和的分布类型是否不变。研究表明,相互独立的随机变量之和的特征函数等于它们的特征函数之积,利用特征函数可以使再生性问题得到简化。

| Abstract: | By using characteristic function,the dissertation studies regeneration problem of random variables which obey the two-distribution and normal distribution.The research indicates that characteristic function for the sum of the independent random variables is equal to the product of their characteristic functions and by using the characteristic function,regeneration problem can be simplified. |

| Keywords: | characteristic function random variable reproducing property |
