| 摘 要： | 利用最新的X光衍射实验数据和Ar原子的弹性散射实验结果，得到了Ar原子间的相互作用和350 GPa下的固态氩的状态方程。这个状态方程可以作为超高压力下的压标。在150 GPa以上的压标，是目前高压研究中急需的。固态氩既可作为准静水压传压介质，又可作为高压X光衍射中的压标使用。本文计算了固态氩的Grüneisen参数、Debye特征参数、定容比热和等温体模量随压力的变化，压力范围为0~150 GPa。

| Abstract: | Based on the latest X-ray diffraction experiment data and the atomic elastic differential cross-section measurements of argon, we obtained Ar-Ar interaction potential and the e-quation of state (EOS) for solid argon under 350GPa. This EOS may be used as the ultrathigh pressure gauge above 150GPa, which is urgently required in current high-pressure research. Solid argon can not only be used as the pressure transmiting medium for quasi-static hydraulic pressure, but also as a pressure gauge for high-pressure X-ray diffraction measurement.In this paper, we also calculated the value of Gruneisen parameter, Debye character temperature, constant volum specific heat, isothermal bulk modulus and their pressure dependence for solid argon in the pressure range from 0-150GPa. |
