| 摘 要： | 本文分析了我国“37”高炮防雹及苏联的防雹效果，基本的看法是:在防雹效果中，爆炸作用是一个相当重要的因素。我们根据爆炸产生的力学效应和润滑效应，以及冰雹在雹云中增长轨迹有集结于沿雹云移向上相对环境水平风速为零的近域内的现象，对爆炸防雹方法的技术要领提出一些建议。

| Abstract: | After the analysis of effective facts reported by scientists of China and USSR in the experiments of hail suppression, an obvious impression has been built. This point is that the explosive effect may play an important role except that of ice–crystallization by seeding. Therefore, the research of explosion effects on the meteorological phenomena has been emphasized in China and USSR. Some important results of this study can be enumerated as follows: The force effect on the airflow at the surrounding of explosion point which may damp the airflow at the speed of 3—4 m/s to zero. The lubrication effect on the motion regime of precipitation particle in the air which may lead on to the increase of fallspeed of hailembryo. There is a region whthin the hailcloud where the hailstone’s traveling trajectories of large hailstones in the growth processes appear to concentrate, and the relatively horizontal wind speed is equal to zero in the direction of hailcloud motion. From above, the technological gists of hail suppression by the method of explosion have been suggested briedfly |
