Different methods are described to measure sludge sedimentation and filtration properties, by use of sedimentation indices, initial sedimentationvelocity and capillary suction time.
利用沉积作用，最初的沉积作用速度和吸附时间，描述测量烂泥沉积作用和过滤产物的不同方法。

In this paper, through outfield experimental research and theory analysis, the Stokes final sedimentationvelocity formula is not demonstrated to adapt to analyzing performance of smoke.
本文通过外场实验研究和理论分析认为，终端沉降速度公式并不适合分析烟幕性能。
