早侏罗世托尔期"大洋缺氧事件"(T-OAE)对应于显著的海洋生态系统的扰动以及气候的快速变化.文章对采自东特提斯开阔海环境中的样品开展了高精度的碳同位素、全岩地球化学和矿物学的分析.使用这些资料,取得了如下进展:(1)建立了东特提斯开阔海环境中高精度的托尔期缺氧事件的记录;(2)揭示了色哇剖面T-OAE的沉积特征,低能黏土岩沉积中突然输入了高能的粗粒沉积,这可能与全球气候变暖导致碎屑沉积物向边缘海和深海海域中供应的增加有关;(3)色哇剖面具有低的C_(org):P_(total)比率,贫或轻微富集氧化还原敏感的微量元素V、Mo和U的特征,剖面序列中生物扰动结构发育,表明色哇地区在早侏罗世托尔期发生了长期的氧化事件,因此,缺氧并不是T-OAE的基本条件;(4)揭示了托尔期缺氧事件的开始伴随着气候的变暖和更润湿,同时发生了多幕式的沉积物源的变化;(5)提出了T-OAE富含有机质沉积物的沉积总体受全球气候的控制,但区域环境的扰动也可能影响了有机质的保存.

OBJECTIVE To inves.igate the correlations.between the expres.ion of thyroid trans.ription factor-1 （TTF-1） and apoptos.s.and angiogenes.s.in lung carcinomas. METHODs.A 829 microarray of the paraffin tis.ue chips.was.cons.ructed, which contained 196 lung carcinomas. 10 normal lung tis.ues. and 1 mus.ular tis.ue. Terminal deoxynucleotidyl trans.eras. mediated nick end labeling （TUNEL） and immunohis.ochemical s. method were us.d to detect apoptos.s.and expres.ion of TTF-1 and CD34 in different types.of lung carcinomas. A Leica Q500 MC image analys.s.s.s.em was.us.d to meas.re and calculate TTF-1 pos.tive unit （PU）, apoptotic index （AI） and microves.el dens.ty （MVD）. REs.LTs.AI of lung s.all cell carcinoma and large cell carcinoma were s.aller than thos. of lung adenocarcinoma and s.uamous.cell carcinoma （P = 0.000）. AI of lung carcinomas.with lymph node metas.as.s.was.s.aller than that of thos. without （P = 0.039）. AI of lung carcinomas.in TNM s.age I-IV was.s.aller than that in s.age I （P = 0.008）. The PU of the TTF-1 was.negatively correlated with AI in s.all cell lung carcinoma （r = -0.752, P = 0.000）. MVD of lung carcinomas.without lymph node metas.as.s.was.s.aller than that of thos. with lymph node metas.as.s.（P = 0.031）. MVD of lung carcinomas.in TNM s.age I was.s.aller than that in s.age I-IV （P = 0.040）. The PU of TTF-1 was.pos.tively correlated with MVD in lung adenocarcinoma （r = 0.708, P = 0.000）. CONCLUs.ON There is.a negative correlation between TTF-1 PU and AI in s.all cell lung carcinoma. TTF-1 PU and AI may be correlated with each other. There is.a pos.tive correlation between TTF-1 PU and MVD in lung adenocarcinoma. TTF-1 may induce the development of lung adenocarcinoma by inducing tumor angiogenes.s.

The s.lvent extinction behavior Of Th(Ⅳ) and Ce(Ⅳ) with Cyanex 925 in nhexane hem nitric acid medium was.s.udied. The extinction mechanis.s.of Th(Ⅳ)and Ce(Ⅵ) by Cyanex 923 were determined by the method of s.ope analys.s. and the extracted s.ecies.might be Th(NO3)4.s.Cyanex 923)(o) and Ce(NO3)4.2(Cyanex 923)(o). The extraction characteris.ics.with purified Cyanex 925 and commercial Cyanex 925 were compared. Res.lts.s.owed Ce(Ⅳ) and Th(Ⅳ) could be s.parted with Cyanex 923 hem RE(Ⅲ) in nitric acid s.lution. The influence of temperature　on the Th(Ⅳ) extinction was.inves.igated and the thermodynamic functions.were calculated.

Binary Al-4Mg alloy have been deformed by hot tors.on at 300-500 deg C ands.rain rates.of 0.006-1.587 s.(-1) to a true s.rain of 5.5. The s.ecimens.were annealed in vacuumfor 1.5 h at 500 deg C and then water quenched. The s.udy indicates.that the dynamicrecrys.alliz.tion occurs.during hot tors.on of Al-4Mg alloy in a certain range of z.parameter(z.ner-Hollmon Parameter), i.e. 19.3 z.s.ng the s.rain rate at higher deformationtemperature or reducing the s.rain rate at lower deformation temperature accelerates.the occurrenceof dynamic recrys.alliz.tion in the alloy.
