Cauchy Problem of the System of One_Dimensional Isentropic Flow

考虑一维均熵流方程组Ｃａｕｃｈｙ 问题，验证了文献［１］ 提出的一个开问题的正确性，并且给出了经典解生命跨度精确估计式．

In this paper the authors consider Cauchy problem for the system of one_dimensional isentropic flow,and verify the correctness of open problem put forward by Academician T.T.Li and as a result the estimates of life_span of C 1 solutions are obtained.
