随机环境中1维紧邻随机游动首达时渐近性质

Asymptotic Behaviour of the First-Arrive Time Series of One-Dimensional Nearest-Neighbour Random Walks in Random Enviroments

随机环境q中1维紧邻随机游动{Xn,n≥0},其首达时Tn,n≥0及其差序列{τn},n≥1的0-律、大数定律成立的条件对应着μ-随机环境q的一个特征量的不同的取值范围.

On one-dimensional neaest-neighbor random walks {X n, n ≥0} in random envi-ronment q, the conditions of 0-1 law and large number law of the first-arrive time series Tn , n ≥0 or {τ n}, n≥1 correspond w ith μ , a feature factor of the random envi-ronment q, in 2 different ranges.
