摘要

摘要: 简要介绍了高压超声测试技术中样品组装的设计原则。设计了一套新的样品组装，并测量了纯Al和纯Cu在常温下的等温状态方程。实验结果表明，新的组装能够实现较理想的准静水压加载，同时也能够测试出良好的超声信号。分析了六面顶压机上常温超声测量的主要误差来源。

Abstract: We introduced briefly the principle of design of sample assembly for ultrasonic measurements at high pressure, and designed a new kind of sample assembly to measure the isothermal compression of Al and Cu at 300 K. Ideal quasi-hydrostatic loading was realized, and high-quality ultrasonic signals were obtained under high pressure. It was indicated that the design of sample assembly was reasonable. We analyzed in brief main uncertainty of ultrasonic measurement in six-side anvil cell at 300 K.
