仿照Mao与Bell的MBC型金刚石砧的设计原理,采用顶盖与筒壁过盈压配合的组合式圆筒设计方案,用磨加工代替电火花加工工艺,自制出三种类型金刚石压砧超高压装置,分别用于光学、X光衍射与布里渊散射研究。利用红宝石荧光测压方法,测量了压砧砧面以及密封垫片流变区内的压力分布。实验结果表明,我们的装置产生的最高压力为1.32Mb,首次测量的支撑压力与Bell等的估计值是一致的。 According to the design principle of MBC diamond anvil of Mao and Bell, the combined cylindrical design scheme of cap and tube wall interference fit is adopted. Instead of EDM, the three types of diamond anvil Device, respectively, for optical, X-ray diffraction and Brillouin scattering studies. Using ruby ​​fluorescence measurement method, the pressure distribution in the anvil surface of the anvil and the gasket was measured. Experimental results show that the maximum pressure generated by our device is 1.32Mb, the first measurement of the support pressure and Bell and other estimates are consistent.
