摘要

摘要: 在活塞-圆筒式高压装置上研究了BaCuO2.5在4.5 GPa内的p-V关系，给出了其状态方程、Grneisen参数0、零压体弹模量B0以及B0的压力导数B0。并在金刚石压砧装置（DAC）上测量了样品的电阻、电容随压力变化的关系，结果表明在0~20 GPa内没有发生相变。

Abstract: p-V relationship for BaCuO2.5 at room temperature and in the pressure range up to 4.5 GPa was obtained using a piston-cylinder type device. Its equation of state, Grneisen parameter 0, bulk modulus B0, and the first order pressure derivative of B0 were also acquired. The resistance versus pressure (R-p), and capacitance versus pressure (C-p) relationships up to 20 GPa were simultaneously studied using DAC at room temperature. The results showed that no phase transition occurred under pressure up to 20 GPa.
