英文摘要：

A class of predator-prey system of two species with ratio-dependence is studied. According to the theory on stochastic differential equation, by constructing the Lyapunov function, and combining with stopping time and some analysis techniques, the existence and uniqueness of global solution for the system are proved. The boundedness and asymptotic estimate of the global solution are also discussed.
