摘　　要：利用Lax对得到广义破裂孤子方程的非局域对称并局域到李点对称。由于谱参数的任意性,故通过引入延拓系统推导出有限变换定理和孤子分子。Nonlocal symmetry of a(2+1)-dimensional generalized breaking soliton equation is derived using its Lax pair,such nonlocal symmetry can be localized to Li point symmetry.Due to the arbitrariness of the spectral parameter,the finite transformation theorem and soliton molecules can be derived by introducing enlarged system.
