摘要
把δ函数引入概率密度,置概率分布于广义函数空间,离散型随机变量也能定义分布密度,概率的应用领域因之而拓展.
Introduced δ -function into probability density, put probability density into generalized fimction denotation space, obtained probability density function of the discrete stochastic variable, thus expanding the field of application of probability.
