We are concerned with the following modified nonlinear Schrödinger system: ,   ,   ,   ,   ,   ,   , where ,   ,   ,   is the critical Sobolev exponent, and    is a bounded smooth domain. By using the perturbation method, we establish the existence of both positive and negative solutions for this system.
