An implicit symplectic scheme is constructed by using central difference scheme in space and implicit Euler-centered scheme in time. In addition, a midpoint rule multi-symplectic method is obtained by applying a cell vertex finite volume discretization to its multi-symplectic form. Numerical simulations are presented for plane wave solution and singular solution of the 2D NLSE. The results demonstrate the effectiveness of the proposed methods. Furthermore, the two methods are analyzed and compared with each other. %K 二维非线性Shr %K dinger方程 %K 辛格式 %K 有限体积法 %K 多辛格式 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=37F46C35E03B4B86&jid=CC77F3CEF526D9CF0B3021650FB4E57E&aid=BD6795DEF97BEF76C3ED727BB4F29182&yid=140ECF96957D60B2&vid=9971A5E270697F23&iid=38B194292C032A66&sid=0C3F9E980968AF79&eid=377D325742940769&journal_id=0254-7791&journal_name=计算数学&referenced_num=0&reference_num=22
