电沉积Ni-W合金镀层的X射线光电子能谱分析

采用X射线光电子能谱（XPS）对电沉积Ni-W合金镀层表面膜进行了分析。研究结果表明，Ni-W合金镀层表面存在一层薄的氧化膜，而钨的氧化作用远大于镍，Ni-W合金镀层中W含量的提高对耐蚀性起决定作用。     

磨损自补偿添加剂在成品油中的摩擦学效应

利用四球试验机考察了二聚酸－3－氯－2－羟基丙单酯（DAE）在4种成品油中的摩擦学性能。试验结果表明，DAE添加剂在L－HM68液压油和L－DAB100空压机油中具有良好的适应性，使其承载能力增强，摩擦系数降低及耐磨性增强；DAE在L－CKE涡轮蜗杆油中使耐磨性增强；DAE在L－CKC150齿轮油中虽使承载能力提高，减磨性增强，但有使耐磨性减小的趋势，说明DAE在不同的油中有不同的性能。     

Alkali-metal Na Adsorption and Promoted Oxidation on Si(100)2×1 Surface

The alkali-metal Na adsorption on Si(100)2×1 surface and its promoted oxidation and Si oxidegrowth have been investigated by means of thermal desorption,work function,Auger electronspectroscopy and photoemission electron spectroscopy.The experimental data showed that therewas a new state,interface electron state,near the Fermi level after the deposition of Na atoms.It wasfound that the presence of Na always caused an increase of the oxygen initial uptake whereas thepromotion of Si oxide growth was observed only at the coverage of Na greater than 0.5 ML.A newmechanism of Na-promoted Si oxide growth is suggested in this paper.     

Production of high-temperature claydite from loams of the Vladimirovskoe Deposit

The possibility of producing high-temperature claydite on the basis of low-grade overburden rocks (loams) of the Vladimirovskoe Deposit is considered. The correcting additives are taken from industrial waste, namely, solar oil and chamotte-kaolin dust from electric filters of rotary kilns.Translated from Ogneupory, No. 4, pp. 26 – 28, April, 1996.     

Assessment of trunk-pipeline survivability taking into account residual welding stresses

A method to calculate pipeline survivability (operability of a part having cracks) taking into account residual welding stresses is proposed. This method allows one to determine the pipeline’s residual life, i.e., to make a conclusion whether the pipeline may be operated after ultrasonic testing detects cracklike defects of a certain size.     

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer was obtained. Criteria for selecting a true solution in the general case were developed and the analysis was conducted for a number of particular cases that may generate practical interest.     

长输管道建设物流管理新模式——物资配送

长输管道工程是以线路管道与沿途站场为主要内容的建设工程,其物资配送有着不同于一般物流管理的特点,点多线长,且交通不便.文章结合西南成品油管道建设工程的物资配送实践,总结出长输管道物资配送的类型,并从机构设置、计划编制、台账和报表管理等方面介绍了物资配送的管理内容及经验,实践证明,这种物资配送方法不但使业主的物资管理人员大为减少,而且使长输管道工程的物资供应更加及时有序.     

Influence of lead on the wear resistance of cast composites of the Fe-Cr-Cu-Ti-C system in sliding friction

The positive influence of lead (2.5%) on the original structure of a cast composite of the Fe-Cr-Cu-C-Ti system, its wear rate, friction coefficient, and the formation of secondary structures is established under the conditions of dry friction and friction with boundary lubrication. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 42, No. 6, pp. 73–80, November–December, 2006.     

日本年轻建筑师的现状——1960年代的这一群

一人脉对照 1 日本现代建筑师溯流 引领日本现代建筑进人成熟时期的领袖人物非丹下健三莫属。由师从丹下的模文彦（1928年-）、黑川纪章（1934年-）以及大高正人（1923年-）、菊竹清训（1928年-）等4人在1960年代创导的新陈代谢运动，使主流的欧美建筑界开始认真关注一个亚洲的小国——日本的建筑活动。可以说新陈代谢运动是日本现代建筑发展的基石也是随后其建筑发展的原动力。
