零截尾泊松分布（zero-truncated Poisson distribution，ZTPD）是用来描述一种偶然机制的概率分布，这种机制的观测装置只有在至少一个事件发生时才开始活动。本文讨论了ZTPD的一种改进形式，我们称之为介入泊松分布（IPD）。我们给出了IPD的起源，并得到了它的统计性质。最后给出了一个数值例子来说明结果。
Among probability distributions that are used to describe a chance mechanism whose observational apparatus becomes active only when at least one event occurs is the zero-truncated Poisson distribution (ZTPD). A modified version of the ZTPD, which we call an intervened Poisson distribution (IPD), is discussed in this paper. We give a genesis of IPD and obtain its statistical properties. A numerical example is included to illustrate the results.
