【Abstract】 The canonical equation of generalized nonlinear Schrodinger equation isobtained by substituting symmetry difference quotient for high order partial derivative and the numerical solution (the normal of wavefunction) is computed by using Eater’s mid-point scheme in this paper. The numerical solution verify that symplectic algorithm is better than nonsymplectic algorithm.更多还原
