石英玻璃在各种高频超声波和声光设备中的用途通常受到材料的声学特性的限制。这封信的目的是报告有关以下方面的最新发现：（1）玻璃状二氧化硅中剪切波的声损耗与频率的关系以及（2）剪切波相速度波动的幅度。关于剪切波传播特性的信息对于主要使用剪切传播模式的超声延迟线应用来说是最重要的。
The usefulness of vitreous silica in a variety of high‐frequency ultrasonic and acousto‐optical devices is often limited by the acoustic properties of the material. The purpose of this Letter is to report recent findings on (1) the acoustic loss‐vs‐frequency dependence for shear waves in vitreous silica and (2) the magnitude of the fluctuation in the shear wave phase velocity. Information on the shear wave propagation characteristics is most important for ultrasonic delay line applications for which the shear mode of propagation is predominantley used.
