使用机械共振来确定凝聚态物理、工程、材料科学等领域感兴趣的材料的弹性模量是一个稳步发展的过程。随着普通个人计算机中大规模计算能力的出现，现在可以通过对一组最低共振的复杂分析来找到低对称性固体的所有弹性模量。这一过程被称为“共振超声光谱”或 RUS，可提供任何常规弹性模量测量技术中最高的绝对精度，并且可以在小样品上快速实现这一点。 RUS 已在其他地方进行了广泛的审查，但仍然缺乏如何使用硬件和软件轻松地为一般科学界进行此类测量的完整描述。在本文中，我们将描述如何实际实现一个有用的 RUS 系统。
The use of mechanical resonances to determine the elastic moduli of materials of interest to condensed-matter physics, engineering, materials science and more is a steadily evolving process. With the advent of massive computing capability in an ordinary personal computer, it is now possible to find all the elastic moduli of low-symmetry solids using sophisticated analysis of a set of the lowest resonances. This process, dubbed "resonant ultrasound spectroscopy" or RUS, provides the highest absolute accuracy of any routine elastic modulus measurement technique, and it does this quickly on small samples. RUS has been reviewed extensively elsewhere, but still lacking is a complete description of how to make such measurements with hardware and software easily available to the general science community. In this article, we describe how to implement realistically a useful RUS system.
