摘要
"Poisson分布的总体均数与其观察单位成正比",这是一个被忽视的性质,但这是一个很基本的性质,在一些问题的解决中它是必需的.本文讨论了这个性质,并举例说明它在实际问题中的应用,然后对此内容在授课过程中的安排提出建议.
‘The mathematical expectation of Poisson distribution is Proportional to its observed units＇ is a easilyignored property of Poisson distribution. But it is a very basic property of Poisson distribution, because it is needed in the solutions of many problems. The application of this property is discussed in this paper. Then how to arrange the part related with this property in teaching is suggested.
