1Optimization of Metal Coverage on the Emitter in n-Type Interdigitated Back Contact Solar Cells Using a PC2D Simulation显示文摘In interdigitated back contact(IBC)solar cells,the metal-electrode coverage on a p-type emitter is optimized by a PC2D simulation.The result shows that the variation of the metal coverage ratio(MCR)will affect both the surface passivation and the electrode-contact properties for the p-type emitter in IBC solar cells.We find that when R_(c) ranges from 0.08 to 0.16Ω·cm^(2),the MCR is optimized with a value of 25%and 33%,resulting in a highest energy-conversion efficiency.The dependences of both Voc and fill factor on MCR are simulated in order to explore the mechanism of the IBC solar cells.张巍 陈晨 贾锐 Janssen G.J.M. 张代生 邢钊 Bronsveld P.C.P.

2New approaches to characterizing urban air particles in central London显示文摘Atmospheric particles in central London during July 1996 have been apportioned to sources by two complimentary techniques: (1) morphological characteristics, determined using high power light microscopy; (2) chemical composition determined by energy dispersive spectroscopy. During the study period, the majority of particles were found to be either biological in origin, or from vehicle related combustion processes. Trends in the latter group of particles are explored further. Numbers of particles per cubic metre were determined at an hourly resolution over a period of six days, and were found to be significantly correlated with other traffic pollutants such as benzene and 1,3 butadiene, although there is no relationship with mass of PM10 as measured by a nearby UK Government monitoring station. We suggest in this paper that numbers of particles from car exhausts are more representative of traffic pollution than current estimates which use monitoring by mass.A.W. Mackay *, X. Long *, N.L.

3间接免疫过氧化物酶技术鉴定猪和牛的肥大细胞显示文摘用小鼠抗人肥大细胞类胰蛋白酶单克隆抗体AA1,AA3及AA5的间接免疫过氧化物酶技术对经Carnoy液或中性缓冲福尔马林(NBF)固定的猪和犊牛空肠、舌及胸腺的石蜡切片进行了免疫染色。对猪和牛的肥大细胞特异性免疫染色与常规的组织化学染色的结果进行了比较。NBF或Carnoy液固定和猪组织经单克隆抗体AA1,AA3及AA5免疫染色显现的肥大细胞在分布、形态和密度方面与甲苯胺蓝或阿尔辛蓝染色切片上的肥大细胞相似。猪组织采用Carnoy液固定,AA5免疫染色效果最好;而采用NBF固定,这三种抗体均可获得十分满意的效果。Carnoy液固定的犊牛组织,AA3和AA5对所有的肥大细胞群体均可得到特异性强的染色,但这些抗体对NBF固定的犊牛组织的免疫染色均不理想。小鼠抗人类肥大细胞类胰蛋白酶单克隆抗体与猪和牛的肥大细胞的交叉反应证实了这些动物的肥大细胞中均含有类胰蛋白酶故使用这些单克隆抗体的免疫酶技术可作为鉴定猪和牛肥大细胞的特异性方法。许乐仁 江萍 M.M.卡尔 K.P.帕尔赛 A.W.瓦尔斯 G.A.霍尔 1997动物学报1997,43,3:5
4黑格尔对道德的批判显示文摘黑格尔的伦理思想以他关于'道德法'和'伦理法'的区分以及对康德道德理论的批判而著名。本文的作者AllenW.伍德从黑格尔早期关于道德问题的思考切入,以《自然法论文》、《精神现象学》以及《法哲学原理》为主要文本,较为系统地阐发了黑格尔对道德的批判。作者认为,黑格尔虽然批判了道德观点的空洞性、抽象性,但是赞同道德是伦理生活的一个方面和现代文化的组成部分。对于黑格尔而言,道德不是形而上学的假设,它要在伦理生活中获得实现。黑格尔与康德的伦理思想并不完全对立,他们共享着同样的伦理价值、理性自治,只是黑格尔试图在康德伦理思想的基础上使道德走出主观性的应该、把伦理价值与社会和历史现实联系起来。A.W.伍德 李金鑫(译) 邓安庆(校) 2013世界哲学2013,,3:4

7Introduction of atomic H into Si_3N_4/SiO_2/Si stacks显示文摘Atomic H generated by a plasma NH3 source at 400 ℃ was demonstrated to passivate dehydrogenated Si3N4/SiO2/Si stacks effectively by bonding with defects in the Si3N4 film and at the Si-SiO2 interface. A subsequent anneal in N2 after atomic H reintroduction was demonstrated to further improve passivation of the Si-SiO2 interface. Isothermal and isochronal anneals in N2 were carried out in order to determine the optimized annealing conditions.WEBER K.J. BLAKERS A.W. 2006Rare Metals2006,25,z1:3

10可持续发展是采矿工业的机遇还是危机显示文摘通过四项资源开发项目的5年研究表明:1)在采矿生产及采矿工业中建立公众信任的关键是清楚、诚实、公开及公正地阐述资源开发工业的核心价值;2)在减少冲突及建立公众对资源开发企业的信任方面,确认可持续发展原则具有十分重要的作用。这两点认识为采矿业的发展指明了方向,同时也提出了巨大的挑战。人们广泛认为采矿不是可持续性工业。从历史上看,采矿工业因其环境、经济及社会责任的粗略界定而加剧了这种感性认识。然而,以上两点认识是可以实现的,实际从理论上讲,采矿并不是与环境、社会及经济的可持续性不兼容的。为此辨护即为本文之主题。A.W.克拉格 宋光明 阚世喆 1999国外金属矿山1999,24,5:2

1364层CT对近端冠状动脉斑块大小分类及定量的准确性:应用血管内超声的比较研究显示文摘OBJECTIVES: We evaluated the accuracy of a new 64- slice computed tomography(CT) scanner, compared with intravascular ultrasound, to visualize atherosclerosis in the proximal coronary system. BACKGROUND: Noninvasive determination of plaque composition and plaque burden may be important to improve risk stratification. METHODS: In 20 patients, a 64- slice CT scan(Sensation 64, Siemens Medical Solutions, Forchheim, Germany) and an intravascular ultrasound investigation of vessels without stenosis >50% was performed. Diagnostic image quality with 64- slice CT was obtained in 36 vessels in 19 patients. RESULTS: In these vessels, which were divided in 3- mm sections, 64- slice CT enabled a correct detection of plaque in 54 of 65(83% ) sections containing noncalcified plaques, 50 of 53(94% ) sections containing mixed plaques, and 41 of 43(95% ) sections containing calcified plaques. In 192 of 204(94% ) sections, atherosclerotic lesions were excluded correctly. In addition, 64- slice CT enabled the visualization of 7 of 10(70% ) sections revealing a lipid pool and could identify a spotty calcification pattern in 27 of 30(90% ) sections. The correlation coefficient to determine plaque volumes per vessel was r2=0.69(p< 0.001) with an underestimation of mixed and noncalcified plaque volumes(p< 0.03) and a trend to overestimate calcified plaque volumes by 64- slice CT. The interobserver variability to determine plaque volumes was 37% . Interobserver agreement to identify atherosclerotic sections was good(Cohen’ s kappa coefficient=0.75). CONCLUSIONS:We conclude that 64- slice CT reveals encouraging results to noninvasively detect different types of coronary plaques located in the proximal coronary system. The ability to determine plaque burden currently is hampered by mainly an insufficient reproducibility.Leber A.W. Becker A. Knez A. 张宪伟 2006世界核心医学期刊文摘(心脏病学分册)2006,2,6:2
