过饱和水汽 meaning in English

supersaturated vapor

The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie , the thickness , the temperature and the supersaturation with respect to ice of the nucleation layer ) . this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water , the density of the supersaturation of the vapor with respect to ice . simultaneously , the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude , and elicits the proper seeding altitude of the catalyst
以此解为依据，得出了不同均流时，人工引入冰核在核化层存留时间，再以此时间作为人工冰核凝华增长时间，求出不同的云宏微观背景(如核化层厚度、温度、冰面过饱和度等)下的冰晶谱分布，经和实际资料比对符合相当好。进而求出核化层中不同过冷水量、冰面过饱和水汽密度下云核化层可允许的催化用量。同时讨论了不同升速，不同高度引入人工冰核时对其存留时间的影响。
