When used along with the Mutex, pthreads conditional variables provide event-based synchronization between threads, but they are synchronous.
当与互斥一起使用时，pthreads条件变量可以在线程之间提供基于事件的同步机制，不过这是同步的。

Adopting algorithm of random event 'conditional probability and introducing condition association coefficient of failure mode can reflect failure dependence of structure.
采用随机事件的条件概率的运算法则，引入失效模式间的条件关联系数来反映结构之间的失效相关性。
