1A review of friction stir welding of steels: Tool, material flow, microstructure, and properties显示文摘Considerable progress has been achieved in friction stir welding(FSW) of steels in every aspect of tool fabrication, microstructure control and properties evaluation in the past two decades. With the development of reliable welding tools and precise control systems, FSW of steels has reached a new level of technical maturity. High-quality, long welds can be produced in many engineering steels. Compared to traditional fusion welding, FSW exhibits unique advantages producing joints with better properties. As a result of active control of the welding temperature and/or cooling rate, FSW has the capability of fabricating steel joints with excellent toughness and strength. For example, unfavorable phase transformations that usually occur during traditional welding can be avoided and favorable phase fractions in advanced steels can be maintained in the weld zone thus avoiding the typical property degradations associated with fusion welding. If phase transformations do occur during FSW of thick steels, optimization of microstructure and properties can be attained by controlling the heat input and post-weld cooling rate.F.C. Liu Y.

2代偿性肝硬化病人食管静脉曲张的双功能多普勒超声的无创性诊断显示文摘目的前瞻胜创建并评价双功能多普勒超声(us)指数对代偿性肝硬化病人(Child—PughA级)是否存在食管静脉曲张的诊断准确度,以内镜结果为参照标准。方法此项研究得到机构审查委员会批准,所有参与者均获得知情同意书。333例病人纳入此前瞻性研究,接受双功能多普勒US与内镜检查,数据分为培训(n=240)和确认(n=143)两组。应用单变量和多变量逻辑回归分析双功能多普勒超声的各项参数,包括平均门静脉流速(PVV)、肝脏阻抗指数、脾阻抗指数和脾指数,以便发现提示食管静脉曲张存在的独立因素。C.H.

3教学过程系统分析——七要素相互作用模型(上)显示文摘用系统观点考察教学过程的各个要素及其联系,这是现代教学论研究的一大进步。本文择要介绍的是美国学者巴特勒(F.Coit Butler)的观点。他长期从事培训咨询、教育技术学、心理学、课程设计等领域的研究与开发工作。在一篇题为《教学过程:一个统一的、相互作用的模型》长文中(刊载《Educational Technology》1985年9、10、11月号),巴特勒从学习理论的基点出发,系统分析了教学过程中的情境、动机、组织、应用、评价、重复和概括七个要素的功能以及在相应的七个阶段中的相互作用联系。我们将看到:巴特勒结合自己三十年研究心得写成的这篇'总结',反映了西方现代教学论中有关教学过程研究的若干新成果和新概念。F.C.巴特勒 盛群力 1990外国教育资料1990,,3:7
4中国石油工业对世界石油市场的影响显示文摘中国石油需求的高速增长和石油产量的有限增长,将对亚太地区和世界原油及油品市场产生影响。预计到2000年中国的油品需求将超过2亿吨,到2005年将增加到2.6亿吨。2000年中国原油产量预计约为1.6亿吨,原油和油品净进口量分别为2000和3000万吨;到2005年原油和油品进口量将分别达到7000和3500万吨。中国缺乏炼油业投资,严重依赖油品进口,可能会带动亚太地区油品价格上涨,同时也会增加中国自己的石油进口费用;而外资进入下游业,目前面临产品定价、市场准入和管理控制等一系列障碍。到2005年,中国的石油消费将高度依赖一个地区即中东所生产的石油。与美国多样化的进口来源相比,在石油供应保障方面,中国的处境并不安全。F.费萨拉基 F.C.唐 韩景城 1996国际石油经济1996,4,2:4

9亚马孙河及其河口区中颗粒有机碳的来源和运移显示文摘本文将碳同位素比值用于研究亚马孙河及其主要支流中颗粒有机碳(POC)的来源,同时也探讨了河流POC向海洋环境的输送,在亚马孙河上游POC的碳同位索值δ^(13)C(-24.5——28.0‰)较之在其中下游的相应值(-27.9——30.1‰)要重一些一般来说,其支流POC的同位素组成要比在亚马孙河主航道中测得的值要轻一些由碳同位素数据证明,亚马孙河主航道中POC的主要来源是陆地物质,而不是河生生物,在亚马孙河口区和淡水舌中观测到POC的同位素组成有很大的变化范围(-17.5——28.4‰),这被认为是河流的POC与海洋的POC在该区域中混合作用的结果。由同位素数据可计算出河流有机碎屑沿平行于河流航道方向向海可搬运至距河口290km处,而沿亚马孙河淡水舌方向在河口西北方向1100km处仍可看到河流POC的稳定同位素信号。蔡德陵 F.C.陈 J.M.艾德蒙德 1989海洋学报1989,11,4:2
