首先用主动-被动分拆法(简称APD)研究Henon同步，该方法实现了全同参数的同步，而对非全同参数出现失同步，可用于保密通信.由于实际中产生连续作用下的耦合同步并非易事，因此，文中还实现了对Henon映射非连续作用(间隙耦合)形式下的混沌同步，只要同步相超过作用的临界值，即可实现准确同步.

The Henonsynchronization of identical systems via active-passive decomposition (APD)have beenrealized. But the chaos synchronization by coninuously coupling is not easy. the Henonsynchronization of unidentical systems by active-occasional coupling have also beenrealized,when the synthronization phases exceed the critical value,the synchronizationHenon mapping via active-occasional copling will be obtained. The synchronization ofunidentical systems will make it potentially useful in secure communicaton.
