摘　　要：在闭合时间路径温度场论基础上 ,导出了直接计算推迟和超前格林函数的一种费曼规则 .利用该费曼规则计算了3 理论中的两点自能和三点顶角函数修正 .Based on the closed time path formalism, a deduced Feynman rule for directly calculating the retarded and advanced Green functions is given. This Feynman rule is used to calculate the two-point self-energy and three-point vertex correction in  3 theory. The generalized fluctuation-dissipation theorem for three-point nonlinear response function is verified.
