Abstract：
In proton linacs the pardcle beams are often focused by isochronic periodic fields, in which the lengths of periods are different but the times the particles travel through each period are constant. In this paper the basic theory of focusing by isochronic periodic fields is discussed. The theory can be generalized to the periodic fields with slow varying peridods.
