摘要
本文研究了随机环境中生灭过程首击间隔随机序列的性质 ,假设环境独立同分布 ,证明了 {τn}∞n =1是 φ 混合随机序列 ,但不是平稳序列 ,并求得期望E(τn)及其极限 。
This a study of the properties for the Birth Death process's just hitting time interval sequence in a random environment,we assume random environment is i.i.d,then,it is proved that {τ n,n=1,2,…} is φ mixing random sequence,but not stationary one,meanwhile,we yield expectation of τ n and it's limit;which is the keys of reasearch it's limit properties.
