We deduce the correlation functions of order parameter by hyperboloid function ( t > tc , t < tc ) , and then compare the two functions to get the change of specific heat , and to get correlation length ? as the token of correlation degree 利用残数定理分别求t t _ c , t t _ c时的关联函数,发生相变时比热的跃变,找到表征关联的特征量? ?关联长度,进一步确定landau理论的适用范围。
