有许多应用程序创建的线程花费了大量时间在睡眠状态来等待事件的发生。还有一些线程进入睡眠状态后定期被唤醒以轮询工作方式来改变或者更新状态信息。线程池可以让你更有效地使用线程，它为你的应用程序提供一个由系统管理的工作者线程池。至少会有一个线程来监听放到线程池的所有等待操作，当等待操作完成后，线程池中将会有一个工作者线程来执行相应的回调函数。-thinks

zemax源码： This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero. -ZEMAX source: This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce xy Gaussian apodization similar to the Gaussian pupi
