| 摘 要： | 本文用图示法表达了粒子云侵蚀/烧蚀问题中各环节之间的联系和各种耦合作用。然后简要地分析了几个主要环节:粒子在激波层中破碎、减速和汽化,高速运动的粒子撞击物面引起的侵蚀,侵蚀过程中多粒子的互相影响,以及粒子云环境中表面气动加热的增量。

| Abstract: | The various correlations and coupling effects between erosion and ablation in hydrometeors environment are graphically expressed. Some main effects, namely (1) the breaking up, retardation and evaporation of hydrometeors in shock wave layer, (2) the erosion by high velocity hydrometeors against surfaces, (3) the multi-particle coupling effect in direct mechanical erosion and (4) the aerodynamic heat augmentation in hydrometeors environment, have been briefly analysed. |
