百吉帕超高压下Ag的X光衍射实验和研究

X-RAY DIFFRACTI0N EXPERIMENT OBSERVATION OF Ag AT OVER 100GPa PRESSURES

详细地介绍了百吉帕超高压实验的方法和步骤。实验是在具有杠杆式的金刚石对顶压砧（ＤＡＣ）高压装置上完成的。以Ａｇ为样品，进行百吉帕超高压下Ｘ光衍射的实验研究。最高压力达１２１ＧＰａ，并获得了若干有意义的实验曲线和结果。

In this paper , the experimental methods and procedures at over 100GPa pressurewere described in detail. The experiments were carried out in a high pressure device with levertype diamond anvil cell (DAC). An in situ over 100GPa high pressure X-ray diffraction observa-tion of Ag was conducted at a pressure up to 121 GPa,some significant experimental curves andresults were obtained.
