| 摘 要： | We propose multisymplectic implicit and explicit Fourier pseudospectral methods for the Klein-Gordon-Schro¨dinger equations.We prove that the implicit method satisfies the charge conservation law exactly.Both methods provide accurate solutions in long-time computations and simulate the soliton collision well.The numerical results show the abilities of the two methods in preserving the charge,energy,and momentum conservation laws.
