主要考虑带有压力小扰动的二维定常等熵流.借助于特征分析的方法,在适当的广义R-H条件和熵条件下,严格证明其初等波对参数ε的依赖性.
主要攷慮帶有壓力小擾動的二維定常等熵流.藉助于特徵分析的方法,在適噹的廣義R-H條件和熵條件下,嚴格證明其初等波對參數ε的依賴性.

The two-dimensional steady isentropic flow with pressure perturbation was considered.With the help of characteristic analysis,under suitable generalized R-H relation and entropy condition,it was rigorously shown the dependence of elementary waves on the parameterε.
