From its title to its contents,the relations of two sexes were reflected.
赵本夫的长篇系列小说《地母》蕴涵着一种浓厚的母性崇拜之情,而且从题目到内容处处都流露出对两性关系的思考。
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.
利用概率母函数,对带有取值恒等于雌性数目的配对函数的两性Galton Watson分支过程,给出了其以概率1灭绝的充分必要条件,并求得了相应的数学期望与方差的表达式。
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.
