摘要
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，进一步给出了一类形如pn的合数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的递推公式，为从概率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 p-valued (p is a prime) random variables, the paper presents the recurrence formula of the equivalent relation between the joint distribution and the distribution of the linear sum of pn-valued (n is a positivie integer) random variables. Withthe method of probability, it provides theoretical basis for the study and construction of multiple-valued logical function which have some characters of cryptography.
