摘要：

By using the perturbation method of multiple scales, we derive coupled nonlinear Schrodinger equations as amplitude equations from coupled nonlinear Klein-Gordon equations. Such coupled nonlinear Schrodinger equations are not necessarily integrable. We present the reductions to the known integrable coupled nonlinear Schrodinger equations.
