摘　　要：冰晶和雪花的产生及融化是一个还未解决的问题。本文指出了研究冰晶雪花融化问题的重要意义，介绍了日本、美国、英国等国科学家在野外及实验室模拟冰晶、雪花融化的一些主要研究结果。对各类冰晶、雪花融化后形成水滴或分裂成多个水滴的个数作者利用实验资料作了分析比较。最后，对如冰系统理论，云中冰晶、雹胚来源，微下击暴流，中尺度对流系统层状区中尺度环流特征与融化的关系及高压传输线上冰、雪融化问题的解决思路也作了有关介绍。The generating and melting of the ice crystals is a basic problem, and have not been settled. In the paper , the importance of the studies of melting problem on ice crystals (snowflakes) has been pointed. The main research results on ice crystals (snowflakes) melting problem in the field and laboratory of scientists in Japan, American , England etc. have been introduced. The numbers of water drops being formed after melting or disrupting of ice crystals (snowflakes) of all kinds,used the laboratory data have been analyses and compared by author. Finally,the ice system theory,the origin of ice crystals and hail embryo in the cloud,micro downburst,and the relation between the mesoscale circulation characteristics and the melting in the meso scale convective system stratiform area have been introduced. And ice (snow) melting problem on the line of power system and solving train of thought have been introduced too.
