This thesis tries to use the theories about freedom and love of Erich Fromm, a German American sociologist, to analyze the contradictory inner world of the protagonist: Herzog s strong longing for active freedom and the fear of passive freedom; love and war between the sexes; the longing for both .

By means of probability generating function,for the bisexual GaltonWatson 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.

On the basis of some elementary theories about Galton-Watson branching process, the bisexual Galton-Watson branching process and the branching process with random environment are introduced in the paper.
