1云南澄江早寒武世地层并论中国的Parabadiella,摩洛哥的Abadiella及澳大利亚的Abadiella huoi(英文)显示文摘根据近来的发现 ,区域地层的阐明及生物在寒武系与前寒武系界线上下的变化 ,澄江早寒武世地层划分作了修订。早寒武世岩石地层名称的更换 ,年代地层及生物地层单位的分带这里作了简述。目前的岩石地层单位从下到上是渔户村组 (梅树阶 ) ,黑林铺组 (筇竹寺阶 ) ,红井哨组、乌龙箐组 (沧浪铺阶 )及山邑村组 (龙王庙阶 )。此层序可分为 12个组合带及 2个亚带。所有的组合带在中国西南地台区都有存在 ,但两个亚带在澄江是区域性的。云南东部震旦系与寒武系的界线暂时置于渔户村组小歪头山段的底界 ,位于小壳化石最早出现的下部。中国的Parabadiella ,摩洛哥的Abadiella及澳大利亚的Abadiellahuoi这里重新作了研究。Parabadiella及Abadiella是两个不同的属。模式标本的图片在这里再次刊出。澳大利亚的Abadiellahuoi一种应是Wutingaspis的一个新种 (WutingaspisjelliChangsp .nov .)。¨Opik( 1975 )的Dolerolenus( ?)sp .nov .一种应归属Parabadiellahuoi一种。Parabadiella是中国也是澳大利亚寒武系最古老的三叶虫。澳大利亚的Wutingaspisjelli的层位与摩洛哥Abadiella的层位相当 ,可与中国的Wutingaspis Eoredlichia带的上部对比。张文堂 L.E.巴比库克 项礼文 孙卫国 罗惠麟 蒋志文 2001古生物学报2001,40,3:9

3钢结构在高层建筑中的作用显示文摘本文是美国著名结构设计师 L·E 罗伯逊(Leslie E·Robertson)于1987年在第20届国际钢铁协会年会上的发言摘译。简要综述了高层建筑钢结构发展状况,介绍了几例具有代表性的世界最高层建筑结构技术,阐述了高层建筑中的钢结构作用。其中有不少构思、观点和处理手法甚为新颖和实用,这对于合理、经济地为发展我国高层房屋建筑钢结构,有很好的借鉴作用。L.E 罗伯逊于1970年设计过高居目前世界第二的纽约110层世界贸易中心大厦,开发了核心筒空间框架体系,最近又与世界享有盛名的贝聿铭建筑师合作,按贝氏构想成功地设计了目前亚洲第一高度的香港中国银行大厦,推出了棱柱体中空巨形桁架体系,建筑结构美观、挺拔、经济,显示了很高成就。该文特由上海冶金设计研究院顾慰祖高级工程师译出,本刊作了部分调整和删节,并加了章节。L.E.罗伯逊 顾慰祖 1990钢结构1990,0,1:3

5Nanoscale deformation of multiaxially forged ultrafine-grained Mg-2Zn-2Gd alloy with high strength-high ductility combination and comparison with the coarse-grained counterpart显示文摘Cold processing of magnesium(Mg) alloys is a challenge because Mg has a hexagonal close-packed(HCP)lattice with limited slip systems, which makes it difficult to plastically deform at low temperature. To address this challenge, a combination of annealing of as-cast alloy and multi-axial forging was adopted to obtain isotropic ultrafine-grained(UFG) structure in a lean Mg-2Zn-2Gd alloy with high strength(yield strength: ~227 MPa)-high ductility(% elongation: ~30%) combination. This combination of strength and ductility is excellent for the lean alloy, enabling an understanding of deformation processes in a formable high strength Mg-rare earth alloy. The nanoscale deformation behavior was studied via nanoindentation and electron microscopy, and the behavior was compared with its low strength(yield strength: ~46 MPa)-low ductility(% elongation: ~7%) coarse-grained(CG) counterpart. In the UFG alloy, extensive dislocation slip was an active deformation mechanism, while in the CG alloy, mechanical twinning occurred.The differences in the deformation mechanisms of UFG and CG alloys were reflected in the discrete burst in the load-displacement plots. The deformation of Mg-2Zn-2Gd alloys was significantly influenced by the grain structure, such that there was change in the deformation mechanism from dislocation slip(non-basal slip) to nanoscale twins in the CG structure. The high plasticity of UFG Mg alloy involved high dislocation activity and change in activation volume.K. Li V.S.Y.Injeti P. Trivedi L.E. Murr R.D.K.

9利用大型水库滞洪库容减轻下游洪水影响显示文摘越来越多变的气候条件引发的高频次极端事件,导致了极端降雨与洪水预估值的持续增大。许多已建大坝已无法应对修正计算的洪水量,而要增强大坝的泄洪能力,又需花费高昂的代价。研究了如何利用增加大型水库的滞洪库容达到梯级水库的最佳防洪效果,以及通过考量整体梯级水库的特性与调度确定最佳洪水调度方案的方法。L.E.尼尔森 董耀华 2016水利水电快报2016,37,3:2

14齿轮压力淬火的基本原理显示文摘多数齿轮在使用中都需要施加适当的载荷,使其发生弯曲,产生压缩应力。要想使齿轮材料达到这些性能要求,就要对其进行热处理,随着热过程的进行,将产生变形。为了控制齿轮的变形并获得稳定的尺寸公差,齿轮在淬火期间受到约束。这种形式的夹持淬火便是齿轮淬火压床的基础。本文就此问题作了阐述。L.E.'skip'Jones 韩丹梅 1994江苏机械制造与自动化1994,,5:2
