| 摘 要： | 真空条件下,常压下已有的烟幕云团的膨胀模型不再适用.本文分析了真空下烟幕形成机理,基于外界对烟幕云团没有扰动的特点,针对燃烧型和爆炸型烟幕在形成阶段的膨胀特性进行数学建模,得到了烟幕云团膨胀过程中体积及质量浓度与烟幕粒子运动速度、运动时间的关系模型,为进一步研究烟幕粒子在大气层外的运动规律提供了理论基础.

| Abstract: | The expansive model of smoke cloud in normal pressure is not applicable in vacuum. The smoke cloud forming mechanism in vacuum is analyzed. Based on the characteristic of noninterference in smoke of environment, the expansive models of the pyrotechnic and explosive smoke in forming course are established according to the expansive characteristic in vacuum, the relation models between the smoke volume, the smoke mass concentration and the smoke particles velocity and move time during the course of smoke cloud expanding are obtained, which provide the theory base for the study of dynamics law of smoke particles in outer space. |
