摘　　要：运用Ｓｔｏｋｅｓ定理，给出了坐标钟同步及钟速同步的充要条件．分别讨论了在有奇点和有奇环的情况下条件成立的时空区域，指出只要本文校钟方案可以实现，任意含有有限个奇点和奇环的时空都可以调整坐标钟及钟速同步．并以Ｖａｉｄｙａ时空为例，指出其中既可以调整坐标钟同步，又可以调整钟速同步．s The necessary and sufficient conditions are separately pointed out for coordinate clock synchronization and clock rate synchronization by using the Stokes' Theorem. The space-time zone, in which singularities (points or rings) exist and the conditions hold true, is analyzed. It is concluded that the coordinate clocks and clock rate can be synchronized in any space-time zone satisfying the above-mentioned conditions. As an example, Vaidya space-time is discussed. Both coordinate clocks and clock rate can be synchronized in it.
