【Abstract】 On the base of research about prediction of road random model of point noise source and according to the quality of the vehicle efflux and inflow,the authors brought out a model of noise source about different kinds of vehicle, which were set by divided time.Through computer simulation, the comparison between value of prediction and actuality indicated that the precision of model was good, and was agree with actual states.更多还原
