本文基于系统的拉格朗日函数，给出了系统的近似解析解。该近似解析解基本上可以描述具有光学晶格的介质中定态传输和运动的实基模的性质。将近似解析解与精确数值解进行了比较，结果表明，在较宽的参数范围内，近似解与精确数值解吻合较好。
Abstract In this article, based on the Lagrangian of the system, an approximate analytical solution is presented. The approximate analytical solution can basically describe the properties of the real fundamental mode in stationary propagation and motion in the medium with optical lattices. Comparison between the approximate analytical solution and the exact numerical solution shows that the approximate solution agrees well with the exact numerical solution in a wide range of parameters.
