摘要
本文在建立了ｐ为一般素数时二维ｐ值随机变量联合分布的分解式的基础上进一步给出了ｐ为部分合数时ｐ值随机变量的联合分布与其分量的线性和的分布之间的等量关系，为从概率论的角度研究和构造具有一定密码学特性的多值逻辑函数提供了理论依据。
Based on the decomposition of joint distribution of 2-dimensional prime-valued random variables,the paper presents the relation between the joint distribution and the distribution of the linear sum of p-valued random variables when p belongs to a part of composite numbers.It provides theoretical basis for the study and construction of multiple-valued logical functions which have some characters of cryptography.
