据调查,我区群众用土炮消雹已有百乡年的历史。特刖是山区群众,已将士炮作为向自然灾害斗争的重要工具。用土炮消雹虽具有明显的效果,但在理论上还没有找到完整的数据,认识还不统一。如有的认为土炮之所以能消雹,是因发射时产生的声波和冲击力,使云层结构遭到破坏,并非土炮发射时产生的热力作用;而有的却认为破坏云层结构与发射时产生的热力作用有关;还有的认为土炮发射时,散在空中的干燥杂质和微粒可以产生凝结作用,使冰雹在未形成之前就降落等等。总之,目前尚无确切论据,这些问 According to the survey, the masses in our district use the gun to hail the soil for a hundred years. Special mines are the people in the mountains who have taken gun fire as an important tool in the fight against natural disasters. Hailstorms with soil artillery have obvious effects, but in theory have not found the complete data, understanding is not uniform. Some people think that the reason why the cannon hail can be caused by the sound waves and impact forces generated when it is fired so that the cloud structure is destroyed and not the thermal effect generated by the launching of the cannon. Some people think that the destruction of the cloud structure and launch Some also think that the launch of the artillery, scattered in the air of dry impurities and particles can have a coagulation effect, so that hail landed before formation and so on. In short, there is no definitive argument, these questions
