摘要：

The meaning of the on-shell variation of the effective action is clarified. The higher orders in the on-shell expansion can be summed up into the coherent state. From these observations, the effective action is shown to have really the property of a generating functional of the S-matrix elements. © 1990 The American Physical Society.
