The first major achievement is obtained with the estabilishment of the state-space method used for 3-D flutter analysis of bridge structures, which works out a solution suitable to many complicated situations, such as ununiform distribution of wind speed field, complex types of the structural systems and different cross sections of decks.

所建立的桥梁颤振分析的状态空间法，不仅通用性强，可以考虑风速场是非均匀的，结构本身是非直线状的，结构单元是多样的等复杂情况，而且计算工作量少，并能提供在整个亚临界区直至临界区结构动力特性随风速而变化的信息。

When a thread owns a critical section, it can make additional calls to EnterCriticalSection or TryEnterCriticalSection without blocking its execution. This prevents a thread from deadlocking itself while waiting for a critical section that it already owns.

但一个线程获得临界区时，如果再次调用 EnterCriticalSection 或者 TryEnterCriticalSection 将不会使其阻塞，这就预防了线程在等待一个自己已经拥有的临界区时死锁自己。
