| 摘 要： | 本文由含时变分原理推导出不含时的S散射矩阵的变分表达式,并且发现玻恩近似,扭曲波玻恩近似及Kohn变分原理的S散射矩阵形式均可被看作是上述变分表达式的特殊形式。

| Abstract: | Time-independent version of the time-dependent variational principle of S-matrix is given. It is shown that both the first order Born (and distorted-wave Born) approximation and the S-matrix version of the Kohn variational principle can be derived from this variational principle. |
