摘      要：The effects of pre-equilibrium emission and secondary decay on the determination of the freeze-out volume are investigated using the isospin-dependent quantum molecular dynamics model accompanied by the statistical decay model ***-mass projectiles and large-mass targets with central collisions are studied at intermediate *** is revealed that the proton yields of pre-equilibrium emission are smaller than those of secondary ***,the determination of the freeze-out volume from the proton yields is more easily affected by pre-equilibrium ***,the percentage of proton yields in the freezeout stage is found to be approxim-ately 50%.
