Abstract：
By using the time aepenaent projection operator to the intrinsic aegreea or freedom, the general theoretical framework of the coupling equations of the relative motion in classical limit, oscillective oscillations and single particle excitations are formulated. For a coupling system simultenously involving the degrees of freedom of the relative motion and the intrinsic excitations (including collective oscillations and single particle excitations). In the first order Born approximation and the random phase approximation of the matrix element of the interaction between phonons and single particle (neglecting the higher terms of the interactions between relative and the phonons, single particle.) the simple coupling equations, which are physically clear and easy for computations, are obtained.These theoretical formulations are expected to be useful for the descriptions of the transport process for the inelastic collision between heavy ions as well as nuclear fission.
