In two recent manuscripts published in Nature,the cholesterol-synthesis pathway was identified as a master regulator of ferroptosis sensitivity and therefore as a novel therapeutic target.1,2 Ferroptosis does not only represent one way to eliminate cancer cells,but also contributes to acute organ damage in the kidney,heart,brain,and liver,and it kills tissues during the process of organ *** term“ferroptosis”should be defined as a cellular process of iron-catalyzed lipid peroxidation-mediated rupture of the plasma membrane.

Journal of Iron and Steel Research International 2008年第3期15卷 92-94,69页

作者： WEI Yao-wu LI Nan CHEN Xiao-xia HU Tie-shan RAO Jiang-ping TAO Xiao-lin Hubei Province Key Lab of Refarctories and Ceramics Wuhan University of Science and Technology Wuhan 430081 Hubei China No. 3 Steelmaking Plant of Wuhan Iron and Steel Group Corporation Wuhan 430082 Hubei China

The silicon pick-up of interstitial-free steel （IF steel） from resin bonded MgO-SiC refractories is studied via a medium frequency induction furnace. Samples of IF steel were heated in MgO-SiC crucibles with mould flux cover at 1 600 ℃ for 180 min. The silicon contents of IF steel samples taken from the molten steel in every 30 min were examined and the refractories after heating were investigated by electron probe microanalysis （EPMA） with energy dispersive spectrometer （EDS）. The silicon content of steel rapidly increased in the first 90 min of beating, and then decreased because of the formation of liquid layer on the refractory. Liquid layer separated the liquid steel from the bulk refractory and stopped the pick-up of silicon. At the same time, desilication via oxygen through the liquid layer and flux started to reduce the silicon content of the liquid steel

对多层板内层短路原因的初步探讨

电子工艺技术 1991年第5期12卷 39-41页

作者：李建军北京机电部15所

随着印制电路布线密度的增加,多层板越来越多地取代双面板。它比双面板有如下优点:布线容量成倍增加;电—地分层,加强屏蔽,减少信号串扰,以及翘曲度、散热性也较好。而且印制板尺寸相对缩小,减小了装备的体积。但采用多层板也有其缺点:... 详细信息

随着印制电路布线密度的增加,多层板越来越多地取代双面板。它比双面板有如下优点:布线容量成倍增加;电—地分层,加强屏蔽,减少信号串扰,以及翘曲度、散热性也较好。而且印制板尺寸相对缩小,减小了装备的体积。但采用多层板也有其缺点:如成本增加、工序增多,相对出现质量缺陷的几率就增加。其制造工艺相对于双面板来说增加了内层成像、内层蚀刻、黑化处理。
