| 摘 要： | 传统烟幕理论认为，在烟幕形成后，烟幕微粒受到重力的作用开始沉降，同时受到空气阻力和浮力的作用，最后使烟幕微粒达到终端沉降速度，这个速度方程可以通过Stokes圆球阻力理论求得，并被用来分析烟幕的性能。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。

| Abstract: | The traditional smoke theory considers that the smoke particles will sedimentate due to gravity after forming of smoke screen, and then the particles reach a final sedimentation velocity thanks to the effect of air-resistance and buoyancy, and the equation can be solved by the Stokes pellet resistance theory and often used to analyze the performance of smoke. In this paper, through outfield experimental research and theory analysis, the Stokes final sedimentation velocity formula is not demonstrated to adapt to analyzing performance of smoke. |
