When this branching processes in random environments is subcritical, it is a certainty that its two copying processes can be migrated a supercritical branching processes in random environments through giving an acute probability generating function derivative.
给定一个繁衍概率母函数均值待定的两状态独立同分布随机环境分枝过程,证明了若该随机环境分枝过程是下临界的,则通过适当选择其繁衍概率母函数均值的取值后,它的两个独立复制过程总能够混合重组为一个上临界随机环境分枝过程;但反之,若该随机环境分枝过程是上临界的,则它的两个独立复制过程不一定总能够混合重组为一个下临界随机环境分枝过程。
