摘要
已有文献中给出了随机变量组列无穷小的定义和判定条件,在此基础上进行了改进,得到了随机变量组列无穷小的4个判定条件,并利用概率的性质和Markov不等式进行了证明.
The definition and judging condition was given in some references, we obtained four sufficient condi- tions of arrays of random variables of infinitesimal based on two lemmas in some references, and we improved them through the property of probability and Markov inequality.
