摘要
In this paper, a new conservative finite difference scheme with a parameter θ is proposed for the initial-boundary problem of the Klein-Gordon-Zakharov （KGZ） equations. Convergence of the numerical solutions are proved with order O（h^2 ＋τ^2） in the energy norm. Numerical results show that the scheme is accurate and efficient.
