被动同步 meaning in English

passive synchronization

In the second part , the synchronization prosperity of several chaotic secure communication methods are discussed and compared , from which we think the active - passive synchronization method is the best one for building chaotic synchronization secure communication system
接着讨论混沌同步保密通信实用化存在的关键问题，对几种混沌同步保密通信方案的同步特性作了研究比较，指出主动?被动同步方案保密通信最适合用来建立混沌同步保密通信系统。
A chaotic synchronized secure communication scheme based on the active - passive pattern , with time - varying behavior via a parameter perturbation technique is proposed in the end of this thesis . the computer simulation and performance analysis results show that the compensation is well done to solve the conflict between the synchronized error and the parameter sensitivity . its capacity against attacks is also discussed
最后以主动?被动同步方法为基础，提出了一种变参数混沌同步保密通信方案，对该方案的抗攻击性、同步特性等各方面特性作了详细的分析，分析结果表明该方案具有一定的抗攻击性与实用性。
