摘要：
Publications on shock-refraction problems typically predict wave patterns resulting from the interaction from the acoustic-impedance ratio. In this note, an analysis based on the shock-impedance ratio is used to derive conditions under which the acoustic-impedance ratio predicts the incorrect type of reflected wave. The range of density ratios for which incorrect types of reflected waves are predicted is found to be quite narrow.
