摘　　要：本文主要是在年金分布的基础上,推广、定义并研究了一类r尾年金分布的存在性和结构,给出了这类分布的存在性条件,证明了在一定条件下,r尾年金分布是年金分布与某一特殊r尾年金分布的混合．The primary objective of this paper is to define the r-truncated annuity distribution, which is a generalization of the annuity distribution in refs： [5], [6]. Conditions for the existence of these distributions are given. It is proved that under certain conditions, the r-truncated annuity distribution is the mixture of an annuity distribution and a special r-truncated annuity distribution.

关 键 词：r尾年金分布 概率母函数 混合.
