| 摘 要： | 用多重光散射法对水蒸气在激波管中的自发成核凝结过程进行了实验研究，分析了膨胀率对成核率和凝结过程的影响。根据理论计算和实测数据结果，所得结论是：膨胀率增大。会造成过饱和度、成核率、凝结质量份额和液滴生长率相应地增大。

| Abstract: | The process of spontaneous nucleation of water vapor hasbeen researched experimently in a shock tube using a method of muItiplelight scattering. Analyze the effect of the expansion rate affected on thenucleation and condensing process.The conclusions based on the theoreticalcalcuation and data results are as follows:increasing the expansion ratewould have derived to increase correspondingly the supersaturation ratio, nucleation rate, condensate mass fraction and droplet growth rate. |
