摘要
数学上推导了二物种类群体系、三物种类群体系和四物种类群体系的物种选择规则,使替代公式引入的总体误差取最小值是物种选择规则的原理.
The species selection equations of two-clades system,three-clades system and four-clades system were deduced mathematically.To minimize the overall errors introduced by replace equation is the key to obtain species selection equations.
