【Abstract】 The Cauchy problem of Euler equations with degenerate linear damping for a perfect gas is studied in this paper,while the initial gas lies in a compact domain. Under some hypotheses on the initial data,the regular solution can be extended globally by the method of energy estimates. These generalize the results of the isentropic Euler equations.更多还原
