在文献[１］的基础上引入了超临界系数以描述液滴冷凝过程；证明了当液滴凝聚相同数量的气相分子时，接触角大于９０°的冷凝器壁面球冠形液滴的化学势减少量将大于冷凝器内部球形液滴的化学势减少量，并且这种化学势减少量均与液滴的曲率半经的４次方成反比，从而将导致冷凝器内部发生Ｂｒｏｗｎ 凝并过程； 探讨了提高冷凝速率的有效途径． Based on the literature [1], supercritical coefficients were introduced to describe the condensation process of droplets. It was proved that when the droplets condensed the same number of vapor phase molecules, the chemical potential of the spherical wall of the condenser spherical contact with the contact angle greater than 90 ° The reduction will be greater than the decrease of the chemical potential of the spherical droplets inside the condenser and this decrease in chemical potential is inversely proportional to the square of the curvature half of the droplet and will result in Brown condensation inside the condenser. The effective way to improve the condensation rate is discussed.
