通过实验研究了涂覆在金属板表面的涂层材料声学性能变化的实时测量方法。设计了一种检测同相差和正交差的实验系统。利用一对角度探头在水性涂料铝板上发射和接收表面波或板波，并实时监测接收到的波信号的幅值和相位差。通过比较涂膜前后的声学特性，计算了接收波信号的衰减和相移。通过板波的衰减和相移，成功地实时监测了涂料的状态变化。
A real-time measurement method for the variation of the acoustic properties of coating materials painted on a metal plate surface was studied experimentally. An experimental system, which detects in-phase difference and quadrature-phase difference, was devised. Surface waves or plate waves were transmitted and received on the aluminum plate with water-based paint using a pair of angle probes, and the amplitude and phase difference of the received wave signal were measured by real-time monitoring. The attenuation and phase shift of the received wave signals were calculated by comparing the acoustic properties with and without the paint. The state change of the paint was successfully monitored in real time from the attenuation and phase shift of the plate wave.
