摘　　要：研究了双势阱束缚下具有含时原子散射长度的弱耦合BEC系统.考虑了2种情况:对应着无含时情况下,系统有一个稳定的静态解;对应没有含时情况下,系统有2个稳定的静态解和一个不稳定的静态解.在含时情况下,混沌会在系统中出现,讨论了其动力学行为.Weakly coupled Bose-Einstein subjected to the double-well potential with time-dependent atomic scattering length is studied in this paper. Two cases are considered：a stable stationary solution of the time-independent system exist in the first case; in the second case, the time-independent system have three stationary solutions, including two stable ones and one instable one. Chaos can appear in the time-dependent system,We have discussed the dynamic of the system.
