摘　　要：考虑非对称的一维周期棘齿势场作用下拉长的玻色-爱因斯坦凝聚原子云的动力学行为.运用直接微扰和积分方程的方法研究了该系统的空间Melnikov混沌特征.理论解析和相应数值结果均表明,此系统在空间坐标具有Melnikov混沌性质.In our report, the dynamical behaviors of Bose-Einstein condensates trapped in one dimensional dissymmetrical periodic ratchet potential were studied. The method of direct perturbation and the method of integral equation were used to analyze the characters of Melnikov chaos in the system. The results suggested that the system has the spatial chaotic behavior.
