Abstract：
The contribution on the inelastic scattering spectra of discrete level part mainly comes from direct reactions.For the sigle-particle emission cross section calculated with the statistical theories,when the incident energy is less than 10MeV the main contribution comes from the equilibrium emission,but when the incident energy reaches 20MeV,more than 90% contribution comes from the pre-equilibrium emission.The contribution of the pre-equilibrium process to the second particle emission can be neglected when the incident energy is less than 20MeV and the contribution of the pre-equilibrium process to the third particle emission can be neglected when the incident energy is less than 50MeV.
