摘　　要：完善了奇异型随机变量的定义,给出了随机变量类型的判别方法以及奇异型随机变量分布函数的常规计算方法.构造了取值半连续的连续型随机变量,澄清了连续型随机变量的取值一定连续的误区,并得出了连续型随机变量的连续函数未必是连续型随机变量的结论.The definition of singular random variable was perfected,the discriminate method of random variable type and the conventional calculation method of distribution function of singular random variable were given.A continuous random variable with semi-continuous values was constructed,a misunderstanding that the value of continuous random variables must be continuous was clarified,and it is concluded that the continuous function of continuous random variable is not necessarily a continuous random variable.
