| 摘 要： | 本文利用Whitham绕射理论,给出了球面激波对平面绕射时马赫杆的近似解,同时求得了马赫反射三波点迹线及壁面超压。另外还导出了新的面积函数表达式。在壁面超压的计算上,这些理论结果与用Whitham方程求得的数值解相符合。

| Abstract: | This paper derives an approximate solution to the Mach stem of diffraction of a spherical shock wave by a plane using the diffraction theory proposed by Whitham. Also, it gives the loci of Mach triple points and the overpressure on the plane. In addition, the author present a new expression of the area function. The agreement between the theroretical results and the numerical solutions of whitham's equations for the evaluation of the overpressure on the plane is favorable. |
