高温高压实验在地球科学、材料科学、物理学领域中具有重要的理论与实际意义。高压测量则是该技术中的关键问题,红宝石荧光压力标定又是一项现代化的测压技术。我们仿改自制了DC-Ⅱ型金刚石高压腔,运用红宝石荧光压力标定测到84.4万巴(844 kb)的静压力水平。目前国际上仅美国卡内奇研究所和通用电器公司可达百万巴(1000 kb)以上的压力。
High-temperature and high-pressure experiments have important theoretical and practical significance in the fields of earth science, material science and physics. High-pressure measurement is the key issue in the technology, ruby fluorescence pressure calibration is a modern pressure measurement technology. We modified and made a homemade DC-Ⅱ high-pressure diamond cavity and measured the static pressure of 844,000 bar (844 kb) using ruby fluorescent pressure calibration. Currently, only the U.S. Carnegie Institute and General Electric Company are under the pressure of over one million bar (1000 kb).
