| Abstract: | According to the limited propagation of the elasto-dynamic system with initial disturbances,with the use of the sobolev-type inequalities and the elliptic estimates methods,a decay estimate for the weighted norm of the solution to the quasi-linear elasto-dynamic system with initial dates is established,the previously similar results is improved. |
