Rotation and tide are two very important physical factors which affect the structure and evolution of the binary system. The distributions of the effective gravitational accelerations which are derived by the highorder perturbation potential have been simulated. The distribution is compared with the one which has been derived from the Roche model. The results show that the distortions of rotation and tide have a significant impact on the effective gravitational accelerations. The maximum can attain 103～104cm／s2 with the initial parameters. Therefore, the distortions can not been neglected in discussing the structure and evolution of the close binary system.
