Such as: calibrating the laser system, calibrating the measurement region and focusing the CCD camera for the diffuser passage with complex shape, selecting the best incidence angle for the laser sheet,, setting the time parameter including the time between pulses and the time between records, designing the laser system, and selecting water fog with 1～5μm diameter as seedings for PIV measurement after comparing several particles. All of the work is useful to accumulate the PIV measurement experience in turbomachinery. 2. Experimental research of the unsteady flow in diffusers The instantaneous velocity fields within the vaneless and vaned diffuser were measured by using PIV technique.

The algorithm first divides the scene into certain layers that do not intersect each other by light's frustums in light space, and generates one shadow map for each layer to ensure that any shadow map does not have the same sample points. Then a faster synthesizing scene shadow method, which avoids operations of pixel layer determination, is given to improve GPU's efficiency.

在光源空间中，利用光源视锥体将场景划分为不相交的多层区域，利用GPU为各层生成阴影图，以确保场景采样点不在多层阴影图中重复出现；同时给出了一种快速综合场景阴影效果的绘制方法，通过避免判断像素层次的操作提高了GPU的利用率。

After all, the usefulness of the finger is in pointing away from itself to the light which illumines finger and all.
