| 摘 要： | 本文从Goldstone定理出发,详细推导了零温度下自旋为1/2的均匀费米系统基态能量的第二级修正。与Green函数的Feynman-Dyson微扰论的计算结果一致。

The 2nd—order correct ions to the ground state energy of homogeneous fermions system deduced by means of goldstone's theorem |

| Abstract: | Starting from Goldstone'stheorem, the author deduces in detail the 2nd—order corretions to the ground state energy of homogeneous spin—1/2 fermions system at zero temperature. The result is the same as that obtained by means of Feynman—Dyson's Perturbation theory of Green's functions. |
