本文研究了反射激波后甲醇蒸汽在激波管端壁上的膜状非平衡凝结。理论预测的过渡现象的生长过程中的液体膜的实验证明：膜的增长约成比例的时间在早期阶段的反射后的冲击波，经过一个过渡期，它的增长成比例的时间的平方根。通过实验与理论的一致性，得到了水蒸气的凝结参数。结果发现，甲醇蒸汽的冷凝参数的大小的十分之一的值为完全捕获的分子在液体表面上。
Filmwise non-equilibrium condensation of methanol vapour is investigated on a shock-tube endwall behind a reflected shock wave. The theoretical prediction of a transition phenomenon during the growth of a liquid film is experimentally demonstrated: the film grows approximately in proportion to the time at the early stages after the reflection of the shock wave and, after a transition period, it grows in proportion to the square root of the time. The condensation parameter of the vapour is obtained from the conformity between experiment and theory. It is found that the condensation parameter of the methanol vapour is of the magnitude of one tenth of the value for the complete capture of the molecules on the liquid surface.
