The underlying model is a two-type branching process.
根据流行病发生的特点,一般其发生的时刻、感染者的人数等因素不易直接得出,但是在某一时间内被发现患病者的人数是可以知道的,从而可以根据该已知数据,利用分支过程构建一个新的模型,利用该方法,可以预测将来流行病的发展情况,从而可以采取相应措施来控制疾病。
By means of probability generating function,for the bisexual GaltonWatson branching process with a certain mating function always taken the number of females as its value,the necessary and sufficient condition of the process extinction with probability 1 was given,and the expressions of expectation and variance of the process were obtained.
