摘　　要：随着Internet网迅速普及,特别是对NOW研究的不断深入,以及并行计算机的推广应用,人们对并发程序的开发需求不断增加,而传统的功能分解方法给并发程序的复用带来了困难,因此有必要将面向对象方法融入并发程序设计以增强程序的易复用性和易扩充性.In order to solve 'inheritance anomaly ',we introduce a new kind of synchronization control model which divides the synchronization control into mutex control and condition synchronization control. Mutex control is completely implemented by pre-compling system and run-time system,so the developers merely concentrate on condition synchronization problem and don't consider mutex problem a-gain when developing concurrent object-oriented programming, which decreases the occurrence of 'inheritance anomaly' and reduces the difficulty of development to a great extend; Condition synchronization control adopts an approach to solving 'inheritance anomaly' based on object's state.
