摘　　要：以双势阱玻色-爱因斯坦凝聚体系为例,给出双势阱BEC的Husimi函数计算方法,并根据数值计算结果,讨论在外加周期调制下,由Husimi函数描述的BEC系统中的隧穿过程。The act of evolutionary and tunneling of Bose - Einstein Condensates （ BEC ） in double - well trap with external periodic modulation can be expressed by husimi function directly. It is a problem to compute husimi function for nonlinear Bose - Einstein condensates. Taking BEC in double - well trap for example, the method of computing husimi function is given. Furtheimore, according to numerical calculation, tunneling procedure of BEC with external periodic modulation is discussed by husimi function.
