4SIMULATION ON HEATING PROCESS IN ULTRASONIC WELDING OF PLASTICS显示文摘The energy conversion during ultrasonic plastic welding is analyzed on the basis of the theory of vis- coelastic mechanics,.The temperature field and the temperature change of the ABS specimen with ener- gy director during ultrasonic welding is simulated with finite element method(FEM). In the simu- lation process,the melting of the energy energy is also considered. The calculation results are in good agreement with the temperature measurement results, which proves that the simulation results are reli- able.S. Q. Yang Z. Dong J. C. Yan and J. B.

5Late Cretaceous biota and the Cretaceous-Paleogene(K--Pg)Boundary in Jiayin of Heilongjiang,China显示文摘An international cooperative study of the Late Cretaceous biota and non-marine strata including the Cretaceous-Paleogene(K--Pg) boundary in Jiayin near the Heilongjiang River,China during 2002-2010,is summarized in this paper. The strata includes the Upper Cretaceous Yong'ancun-,Taipinglinchang-,Yuliang-zi-,and Furao formations,and the Paleocence Wuyun Formation consisting of Baoshantou Member and a Coalbearing Member. Seven palynological assemblages from Santonian to Paleocene are recognized,which is used for definition of the K--Pg boundary. Through the palynological analysis of three drilled boreholes (XHY-2005,2006,2008) in Xiaoheyan of western Jiayin,the K--Pg boundary is defined within 20. 00-20. 05 m in the borehole XHY-2006 (as a standard boundary) which is just between the top of Furao Formation (late Maasterichtian) and the base of Baishantou Member (early Danian) . These new research results are supported by paleo- magnetic,geochemical and other analyses,also. On the other hand,the presence of eight taxa of Maasterichtian dinosaurs (mostly hadrosaurids) have been recognized by the authors; and two mega-plant assemblages from the Yong'ancun Fm (Santonian) to Taipinglinchang Fm (Campanian) are confirmed. These research a-chievements indicate that the Upper Cretaceous-Paleocene in Jiayin can be well correlated to the strata in the neighboring Zeya-Bureja basin,Russia. The K--Pg boundary definited in Jiayin is the first well documented non-marine K--Pg boundary in China. Also the related paleoclimate,paleoenvironment and the mass extinctions in this area during the Cretaceous-Paleocene transition are also discussed.Sun G. Akhmetiev M. Markevich V. Ashraf A. R.

6Diversity of microbial plankton across the Three Gorges Dam of the Yangtze River,China显示文摘长江的三个峡水坝(TGD ) ,中国,在世界上是最大的灌溉和水力发电的工程工程之一。效果巨大人造象动物志和 macrophyte 上的 TGD 一样的工程是明显的,主要通过水动力学和流动模式的变化;然而,微生物怎么对如此的变化作出回应,是不太清楚的。这研究被瞄准在不同季节和地点在微生物引起的差异检验差别(在前面并且在 TGD 后面) 。另外,依附粒子、免费生活的社区之间的差别也被检验。在水列在后面并且在 TGD 前面的全部、潜在地活跃的微生物的社区结构与基于 DNA 、基于 RNA 的 16S rRNA 基因被分析在三个不同季节的种系发生的途径。16S rRNA 基因的克隆图书馆从提取 DNA 在扩大以后被准备并且为一些样品,在从提取 rRNA 准备 cDNA 以后。差别在不同季节并且在免费生活、依附粒子的社区之间在地点之间被观察。细菌并且 archaeal 社区比在冬季在夏天是更多样的,由于在夏天的更高滋养的层次和更温暖的温度比在冬季。依附粒子的微生物比免费生活的社区更多样,可能因为在粒子的更高滋养的层次和异构的 geochemical 微型环境。在细菌的社区结构的空间变化被观察,即,在 TGD 后面的水水库(在上游) 比在水坝前面招待了更多样的细菌的人口(下游) ,因为沉积和水从的多样的来源对水库在上游。这些结果在水坝建设影响的河生态系统为我们对环境变化的微生物引起的社区的回答的理解有重要含意。Shang Wang Raymond M.

13WELDING BETWEEN HIGH MANGANESE STEEL AND HIGH CARBON STEEL显示文摘Manuscript received 30 July 1999 Abstract The shielded metal arc welding (SMAW) of a manganese steel part as a crossing of railway track to a carbon steel part as the rails of the railroad is the welding of dissimilar steel. It are was known that it is not possible to the the rail of railroad directly to the cross- ing of railway track made from a steel containing about 14% of manganese (wt. ) because of so many differences between the two kinds of steels such as composition, microstructure,mechanical properties and weldability.A method was used to solve the problem by presetting an intermediate layer on each side of the joint and other special procedures were used.The result of test indicated that a good weld joint was obtained.M.
