摘　　要：本文比较了带干扰的两类不同风险模型.首先研究了在不同保费计算原理下各风险业务的相关性是如何影响保费率计算的,进而通过鞅方法推导出两类模型破产概率的Lundberg指数和Lundberg不等式,最后比较了在不同保费计算原理下两类模型的Lundberg指数的性质.In this article,the authors compare two different risk processes perturbed by diffusion.The authors first study how the dependence between the classes of business influence on calculation of the premium according to different premium principles.Then their Lundberg exponents and Lundberg inequalities are concluded through martingale theory.Finally,the authors compare the Lundberg exponents of these two models under different premium principles.
