| Abstract: | Based on the generic dynamical model proposed by Huang et al.,the evolution of dynamics with time in the interstellar medium is studied in detail by numerical methods. Taking the effect of synchrotron self-absorption into account,the evolution under different frequencies of afterglow with time is obtained with numerical calculation methods. The paper draws the corresponding conclusions by comparing the data with the cylindrical jet model. |
