97-06624 Mao The PIs propose new experiments on the elasticity and equations of state of mantle and core materials (eg. periclase, stishovite, ringwoodite, majorite, Mg-Fe silicate perovskite, FeO, Fe) to address a broad range of problems in geophysics. Recently developed techniques, including new diamond-anvil cell (DAC) design, high-temperature laser-heating and resistive-heating techniques, synchrotron single-crystal and polycrystal x-ray diffraction, and Brillouin scattering spectroscopic techniques will be used to study a wide array of materials of importance in studies of earth's mantle and core. ***

97-06624 MAO PI提出了关于地幔和岩心材料的弹性和状态方程的新实验(例如。方镁石、辉钛矿、环木矿、莫来石、镁铁硅酸盐钙钛矿、FeO、Fe)，以解决地球物理中的一系列问题。最近发展起来的技术，包括新的钻石顶压腔(DAC)设计、高温激光加热和电阻加热技术、同步加速器单晶和多晶X射线衍射以及布里渊散射光谱技术，将被用来研究在地幔和地核研究中具有重要意义的各种材料。***
