2SEASONAL AND DIURNAL VARIATIONS OF PM_(1.0),PM_(2.5) AND PM_(10) IN THE ROADSIDE ENVIRONMENT OF HONG KONG显示文摘PM1.0 (fine particles, with diameter < 1 μm), PM2.5 (fine particles, with diameter < 2.5 μm) and PM10 (coarse particles, with diameter < 10 μm) were measured at 24-hour intervals near a high-traffic road in Hong Kong, from October 2004 to September 2005. Mass concentrations were determined for the three particle fractions, averaging for PM1.0, PM2.5 and PM10, respectively, 44.5±18.4, 55.4±25.5 and 81.3±37.7 μg?m-3. PM2.5 was 3.7 times the U.S. EPA’s annual NAAQS of 15 μg?m-3. Overall, PM1.0 accounted for 44 to 69% (average 57%) of PM10, while PM2.5 accounted for 58 to 82% (average 71%) in this study. The particulate masses showed obvious seasonal patterns with high concentrations in cold seasons and low in warm seasons, especially high concentrations of PM2.5-10 during the cold seasons. Diurnal variations of mass concentrations of PM2.5 were determined during July, showing two major peaks in the morning and afternoon rush hours.K.F. Ho S.C. Lee S.W.

3SUPERPLASTICITY AND DIFFUSION BONDING OF IN718 SUPERALLOY显示文摘The superplasticity and diffusion bonding of IN718 superalloy were studied in this article. The strain rate sensitivity index m was obtained at different temperatures and various initial strain rates using the tensile speed mutation method; m reached its maximum value 0.53 at an initial strain rate of 1×10-4s-1 at 1253K. The diffusion bonding parameters, including the bonding temperature T, pressure p, and time t, affected the mechanism of joints. When the bonded specimen with 25μm thick nickel foil interlayer was tensile at room temperature, the shear fracture of the joints with nickel foil interlayer took place at the IN718 part. Microstructure study was carried out with the bonded samples. The microstructure shows an excellent bonding at the interfaces. The optimum parameters for the diffusion bonding are: T = 1273-1323K, p = 20-30MPa, t = 45-60min.W.B. Han K.F. Zhang B. Wang D.Z. Wu 2007Acta Metallurgica Sinica(English Letters)2007,20,4:8

5EFFECTS OF HIGH-DENSITY CURRENT PULSES ON WORK HARDENING BEHAVIORS OF AUSTENITE STAINLESS STEEL IN WIRE-DRAWING DEFORMATION显示文摘The influence of high-density pulsing current on the work-hardening behavior of H0Cr17Ni6Mn3 and 1Cr18N19 stainless steels in wire-drawing deformation processes has been studied. It was found that the drawing stress and the work-hardening rate of wires were significantly reduced by applying current pulses in drawing process. The work-hardening behavior of the multi-courses drawing deformation can be well de scribed by Hollomon formula σ = κεn. With the application of current pulses in drawing deformation, the work-hardening exponents of H0Cr17Ni6MnS steel wires and 1 Cr1 8Ni9 stainless steel wires were reduced by 33% and 45%, respectively, and their work-hardening coefficients were reduced by 41% and 47%, respectively. It was also found that the work-hardening coefficient of wires was reduced with the increment of the frequency of current pulses, while the work-hardening exponents of both steels were insensitive to the pulsing frequency.K.F.

6INTRODUCTION OF NEW ANTICORROSIVE DESIGN FOR REACTORS EXPOSED TO HIGH TEMPERATURE AND HIGH PRESSURE HYDROGEN显示文摘This paper integrates the characteristic of structure design and manufacture and maintenance for Chinese flat steel band wound pressure vessel(UCWPV) with the problems existing in current in service high temperature and pressure vessel exposed to hydrogen. In view of economy and safety it is suggested that it be practicable for UCWPV to act as reactors for platreating, hydrogenating, and catforming. UCWPV has not only potential advantages, but also removes shortages present in in-service reactors for hydrogen.J.L. Li 1,2) , K.F. Wong 3) and G.H.

7法律与人类学显示文摘几乎早在20年前,里斯曼(Riesman)就发表了一篇文章,批评法学家的法律中心主义观点,并倡议人类学家研究美国法律组织的结构、作用,以及法学家的活动。但是,从事这种研究的人类学家寥寥无几。事实上,只有极少数人类学家把一般性的法律研究作为自己特殊的研究范畴,也许我国有十几位人类学家做到了这一点。尽管如此,如今这个领域正吸引着越来越多的人。只要浏览一下近几年关于民族志研究专题文章的目录和素引,就会看出:一方面,大部分人类学家对他们所研究的民族的法律置之不理。相反。K.F.科克 杨周云 1987世界民族1987,,6:3

12论中国和世界大地构造学说的危机(英文)显示文摘当今大地构造学的危机在于权威专家不承认地球是旋转的。绝大部分构造学家的学说是建筑在不运动的地球模型上的。就旋转的地球模型和不运动的地球的模型而言,其地球动力学规律存在着本质的区别。由于地球确实在旋转,我们有理由相信研究者迟早会承认旋转的地球模型。但是启用新模型不是一件简单的事,必须克服某些传统,而且,很多构造规律要在“一张白纸上”重新建立。K.F.贾普金 2004Petroleum Science2004,1,3:2
