Behavior ofFe-bearing materials under very high pressure and mineralogy of the lowermost mantle and the inner core

通过多砧和金刚石砧细胞实验，结合从头计算，研究了从下地幔深处到地球内核的压力和温度条件下，铁和含铁矿物的行为。本研究取得了一系列重要的研究成果，如铁在下地幔中的分配和铁在内核中的相关系，以及纳米聚晶金刚石（NPD或HIME-diamond）应用于各种高压仪器的技术进展。

Behaviors of iron and iron-bearing minerals have been studiedby both multianvil and diamond anvil cell experiments, in conjunction with ab initio calculations, under the pressure and temperature conditions from the deep lower mantle to the inner core of the Earth. A number of important results such as relevant to the partitioning of iron in the lower mantle and the phase relations of iron in the inner core, as well as technological developments in applying nano-polycrystalline diamond (NPD or HIME-diamond) to various high-pressure apparatus, have been obtained in this study.
