Finally,the tool of martingale is used to study the proliferation rate of linear controlled branching process in a random environment.
引进了随机环境中线性控制分枝链的基本概念,讨论了这种概率模型的灭绝概率,用生成母函数严格表达了第n步灭绝的概率,进而讨论了各类母函数之间的关系,并得到了随机环境中线性控制分枝链的期望公式;基于以上的结果,采用鞅方法,严格表达了随机环境中线性控制分枝链的增殖速度。
Objective:To investigate the status of accelerated repopulation in the CNE-2 cell lines during irradiation,find the optimal time points of accelerated repopulation in nasopharyngeal carcinoma(NPC)CNE-2 cell lines after irradiation,and provide experimental data for NPC late course accelerated hyperfractionation(LCAHF)radiation therapy.
