本文研究了平面激波在两种不同气体界面上的折射问题。研究表明，运动方程可以简化为一个12次多项式方程。详细的数值计算结果分别为空气-CH 4和空气-CO2界面，这是“慢快”和“快-慢”的组合。将计算结果与实验结果进行了比较，两者吻合较好.数值结果是多值的，但发现总是最弱的解与实验数据吻合。常发现方程的重根与退化和不规则波系的出现有关，并对这些系统作了一些分析和讨论。
The paper deals with the refraction of a plane shock wave by an interface between two different gases. It is shown that the equations of motion can be reduced to a single polynomial equation of degree 12. Detailed numerical results are presented for the air-CH4 and the air-CO2 interfaces, which are respectively ‘slowfast’ and ‘fast–slow’ combinations. When the results are compared with experiment good agreement is obtained. The numerical data are multi-valued, but it is found that it is always the weakest solution that agrees with the experimental data. The multiple roots of the equation are often found to be associated with the appearance of degenerate and irregular wave systems and some attempt is made to analyse and discuss these systems.
