9304622 Mao Recent experimental advances in high-pressure technology have provided the ability to simulate the P-T conditions of the entire Earth in the laboratory. This award is for continued support of a systematic study of the equations of state and elasticity of Earth materials with diamond-anvil cells. The PIs will use synchrotron x-ray diffraction techniques to determine lattice parameters and molar volume, and to use Brillouin spectroscopy to determine compressional and shear wave velocities, both at high P and T. With recently established experimental techniques, they will systematically acquire a comprehensive and accurate database representative of realistic Earth compositional models. ***

9304622 MAO最近高压技术的实验进展提供了在实验室模拟整个地球的P-T条件的能力。这一奖项是为了表彰对使用钻石砧座对地球材料的状态方程和弹性进行系统研究的持续支持。PI将使用同步加速器X射线衍射技术来确定晶格参数和摩尔体积，并使用布里渊光谱来确定在高P和T下的纵波和横波速度。利用最近建立的实验技术，他们将系统地获得代表现实地球成分模型的全面和准确的数据库。***
