纯平表面声波触摸技术 True Flat SAW Touch
提出了通过平面声波分解测量热声谐振管中单频压力波声功的方法。
A method for measuring the mono sound power in thermoacoustic resonator was developed by using the theory of plane wave decomposition.
即使在平面声波条件不甚满足的情况下，其定向的相对误差也只有3.3%。
In some cases, although the condition of plane sound is not too satisfactory, the relative error of the azimuth is only 3.3%.
考虑到这些特征，再假设海水与沉积物的界面是平的，导出了平面声波在其上的反射系数的表达式。
When these characteristics are considered and assume that the interface of sea water and sediment is a plane, the expression of reflection coefficient is derived.
