介绍了利用同步辐射X射线衍射技术,结合金刚石压砧技术,研究材料在高压条件下的状态方程,以润滑剂MoS2为例,用BirchMurnaghan状态方程来拟合实验数据,得到材料的体和弹性模量。
The investigation of equation of state (EOS) for matter under high pressure conditions by synchrotron radiation Xray diffraction in combination with diamond anvil cell (DAC) are introduced in this paper. Taking lubricant MoS2 as an example, a method of fitting experimental data with BirchMurnaghan EOS to obtain the bulk modulus of materials is presented.
