摘要
给出带干扰风险模型中破产概率的Ｆｅｌｌｅｒ表示，并证明带干扰风险模型的破产概率的二次连续可微性．
in this paper, we present the Feller expression for the ruin probability of the classical risk model that is perturbed by diffusion. Basing on the Feller expression, we prove the twice continuous differentiability of the ruin pribability under certain conditions.
