| 摘 要： | 基于Sakai-Bodin-Petersen理论，我们求解了对称的双约瑟夫森结的耦合非线性方程组．结果表明，线性化方程组的同相和反相解所对应的两种磁通运动模式也存在于原始的非线性方程组的解中，同时非线性方程组独有的位相锁定的扭折（kinks）形式的磁通运动在低能情况下会演化为孤子解．

| Abstract: | Based on Sakai-Bodiu-Pedersen theory, we have solved the coupled equations of two vertically stacked symmetrical Josephson junctions. The solution shows that the two modes of fluxon motion corresponding to in phase and out of phase solutions of the linearized equations also exist for the original non-linear equations, and that the fluxon motion in the form of kinks, which reduces to soliton solution in lower energy case, is unique to the non-linear equations. |
