在负泊松比材料中观察到一个有趣的现象，即在满足Wiechert条件的接触介质的不同声学性质下，界面Stoneley波出现异常的速度交点。与非auxetics（具有正泊松比的材料）的比较分析揭示了不存在这样的交叉。分析的基础上解决长期方程的斯通利波的修改Scholte形式。
Abstract An interesting phenomenon observed in auxetics (materials with negative Poisson’s ratio) relates to appearing anomalous velocity intersections of the interfacial Stoneley waves at varying acoustic properties of the contacting media satisfying Wiechert condition. Comparative analysis with the non-auxetics (materials with positive Poisson’s ratio) revealed the absence of such intersections. The analysis is based on solving secular equation for Stoneley waves in the modified Scholte form.
