摘要
讨论了一类个体的寿命有限且一生分为若干个阶段的纯生过程 (pure birth pro-cess),其中每个阶段的存活率,繁殖率,其繁殖符合 Poisson过程.证明了其小群体的繁衍分布服从分布;i和j两个不同阶段繁殖的时间间隔之比的密度函数为Fibonacci过程[4]中总体的期望数和寿命与指数分布有关等性质.
A type of pure birth process is discussed, in which individuals have finite life and the life of the individual is divided into L stages, in each stage the survival rate , birth rate and the process of birth obeys the Poisson Process. The paper shows that the distributions of birth rate among small groups are given by the distribution; the distribution density for pro portion of the time intervals between the ith and the jth stages is given by in the Fibonacci Process[4] the expectation of quantity and life for species are related to the exponential distribution.
