Resonant Ultrasound Spectroscopy (RUS) is an ultrasound-based minimal-effort high-accuracy elastic modulus measurement technique. RUS as described here uses the mechanical resonances (normal modes of vibration or just modes) of rectangular parallelepiped or cylindrical specimens with a dimension of from a fraction of a millimeter to as large as will fit into the apparatus. Provided here is all that is needed so that the reader can construct and use a state-of-the-art RUS system. Included are links to open-source circuit diagrams, links to download Los Alamos National Laboratory open-source data acquisition software, links to request free analysis software, procedures for acquiring measurements, considerations on building transducers, 3-D printed stage designs, and a full mathematical explanation of how the analysis software extracts elastic moduli from resonances.
共振超声光谱法（RUS）是一种基于超声的、操作简便且精度高的弹性模量测量技术。这里所描述的RUS利用长方体或圆柱体试样的机械共振（振动的正常模式或简称为模式），试样尺寸从几分之一毫米到能放入仪器的最大尺寸。本文提供了读者构建和使用先进RUS系统所需的所有内容。包括开源电路图链接、下载洛斯阿拉莫斯国家实验室开源数据采集软件的链接、申请免费分析软件的链接、测量获取程序、换能器构建注意事项、3D打印平台设计，以及分析软件如何从共振中提取弹性模量的完整数学解释。
