摘要
目前国内出版的有关分析概率方面的书,在讨论稳定特征函数S时,一般均给出了其范式形式作为必要条件,但是却极少涉及到范式本身也是S的充分条件这一点,本文将在文献[1]的基础上给出这个充分条件的一种证法,且把S的充要条件扩展到更加一般的形式。
When stable c. f.class is discussed,domastic works on analytic probability published so far usurally give its normal form as a necessary condition, but they ignore the fact that the normal form is also the sufficien condition for stable c.f.class.This paper puts forward a proof of the safficient condition on the base of[1],and expands the sufficient and necessary condition to a more general form.
