摘要

摘要: 综合使用超声相干技术几种不同的测量方法，分别研究两类三种不同性能的玻璃材料，测量它们的声速和衰减在室温及高压条件下的变化规律。结果表明：两类玻璃的声速和衰减以及由此而得到的弹性常数存在较大差异。两种硅玻璃在高压下，声速随压力变化的规律相似，压力升高时，纵波速度随之单调增加，横波速度线性减少，纵波衰减也随压力升高呈增加趋势。不同的是：两种玻璃横波衰减随压力的变化规律完全相反，水白玻璃的衰减增加，窗口玻璃的减小。上述几种方法的测量结果基本一致，且在相应的压力范围内与布里渊散射的实验结果基本吻合。

Abstract: The ultrasonic interferometer techniques－phase comparison method, pulse echo overlap, pulse superposition and phase detection have been combined together to study the elastic properties of three types of glass under different pressures and room temperature. These glasses are named by silicate glass (water white glass and window glass) and polystyrene. The results show that there exists a big difference in the ultrasonic velocities, attenuations and elastic constants at room temperature between silicate glass and polystyrene. At high pressure, the pressure dependences of velocities are similar for both types of silicate glass: the velocities of longitudinal waves increase as pressure increased, while the velocities of shear waves decrease linearly, and the attenuations in longitudinal waves also increase with pressure. However attenuations of shear waves for the two types of silicate glass vary oppositely with pressure, the attenuation goes up with pressure for water white glass, and goes down for window glass. The results obtained by above techniques are consistent, and is in agreement with Brillouin scattering data at corresponding pressure range.
