摘要
概率统计中的正态分布是一个十分重要的分布,它的应用非常广泛,它的一些问题的处理与广义积分有着密切的联系,而某些广义积分又可以借助正态分布的有关概念、性质,方便地求出.本文从利用正态分布有关概念求解一类广义积分的讨论中,揭示了不同数学分支间的内在联系.
Normal distribution, which is widely applicable, is a very important part in probability. It is in close contact with generalized integral. Some generalized integrals can be easily computed by the concept and property of normal distribution. This article explains the inner contacts among different branches of mathematics in the discussion of solving a certain generalized integral by the concept of normal distribution.
