摘要：

We propose an improvement for the average action which helps to decouple particles with heavy masses. Comparison is made with various other formulations for effective actions for which the short distance degrees of freedom are integrated out. In particular, the improved average action is closely related to a scale-dependent effective action for which an exact evolution equation was found recently.
