摘要
建立了污染物排放对微生物种群生灭影响的模型,研究了随机时刻灭绝概率Ψ(x,T)的一致渐近性,并最终得到一致渐近公式Ψ(x,T)~Eλ(T)(?).
The present paper builds a model about the birth and death of microbiology population that suffered from pollutant,and investigates the uniformly asymptotic behavior of random time death probability.At last,under some mild assumptions,we obtained a simple asymptotic relation for random time death probability,that isψ(x,T)~Eλ(T)F.
