    • 摘要: Synchrotron radiation x-ray diffraction investigations of iron(Fe)and nickel(Ni)are conducted at pressures up to 354 and 368 GPa,respectively,and the equations of state(EOSs)at 298 K for the two elements are obtained for data extending to pressures as high as those at the center of the Earth,using the latest Pt-EOS pressure scale.From a least-squares fit to the Vinet equation using the observed pressure–volume data,the isothermal bulk modulus K0 and its pressure derivative K′0 are estimated to be 159.27(99)GPa and 5.86(4)for hcp-Fe,and 173.5(1.4)GPa and 5.55(5)for Ni.By comparing the present EOSs and extrapolated EOSs reported in the literature for Fe and Ni,the volumes of Fe and Ni at 365 GPa are found to be 2.3%and 1.5%larger than those estimated from extrapolated EOSs in previous studies,respectively.It is concluded that these discrepancies are due to the pressure scale.The present results suggest that the densities of Fe and Ni at a pressure of 365 GPa corresponding to the center of the Earth are 2.3%and 1.5%,respectively,lower than previously thought.

    • 摘要: 1It was commencement at our college.People were pouring into the hall as I entered it.Finding the choice seats in the center of the hall already taken,I pressed forward,look⁃ing to the right and left for a seat.Finally,I found one in the very front row.2Here a little girl moved along to make room for me,looking into my face with large gray eyes.Again and again I found my eyes turning to the rose⁃like face,and each time the gray eyes moved half⁃smiling to meet mine.
    • 摘要: Orion矿业金融集团【OrionMine Finance Group】日前披露,该公司与Premier黄金公司【Premier Gold Mines(TSX:PG)】Centerra黄金公司【Centerra Gold(TSX:CG)】签收一项协议,出资2.25亿美元收购Centerra黄金公司旗下Greenstone Gold金矿50%股份,不过Orion矿业金融集团还需要承担该矿山约7500万美元的债务。目前Premier黄金公司持有Greenstone Gold金矿剩余50%股份。

    • 摘要: 虚拟化安全的3个关键问题虚拟化代表着IT实践的巨大变化。虚拟化的发展经历了有时称为“虚拟化停滞”的过程。这是指许多组织将其服务器总数的25%进行了虚拟化,然后进度停止了。实际上,安全团队并不确定如何在虚拟化环境中应用为物理环境设计的实践,虽然有这样的困惑,但是方向是明确的:安全实践必须更新,以打破虚拟化的僵局。
    • 摘要: C位出道debut in acentral role“C位出道”作为最火最出園的词汇应该如何用英文表述呢?“C位”中的“C”的含义尚无定论,一说“C”指carry,意为“担负团队的责任”;另一种说法是“C”指center,“C位”就是acentralrole,即“中心位”。“出道”这个词可以用debut来表示,这个词源于法语,意为“初次登台”。因此,“C位出道”可以翻译成debut in a central role,你学会了吗?
