摘　　要：探讨了个体索赔分布的重尾问题,提出了商分布及较重尾分布的概念,具体讨论了重尾分布间的比较,并提供了判断重尾分布的方法。In order to meet the needs of recent research in applied probability, the heaviness of distribution is studied. The heavier heavy-tailed distribution and the quotient distribution are needed. A series of problems are discussed related to the heavier distribution and point out the relations of heavy-tailed distrbutions.
