作者： wang Dan wang {2. School of Resources and Environmental Science East China Normal University Shanghai 200062 China department of Geography Shanghai Normal University Shanghai 200234 China College of Urban and Environmental Science Northeast Normal University Changchun 130024 China

The investment of Samsung Electronics in china is divided into three types： production companies, sales companies and R＆D institutions. Based on an analysis of the spatial structure of Samsung＇s three types of investment and parent company, it is put forward that regional bias exists during the operation of a multi-national corporation （MNC） in china, i.e., regional biases of technology, price, sales as well as decision-making. Front office and back ofrice, two terms related closely with the location of modern MNCs, are defined and locational principles of each are studied. It is pointed out that production companies and R＆D institutions belong to back office, while sales company falls into the type of front office. Based on a summarization on the spatial distribution of production companies, sales companies and R＆D institutions, the locational principles of front office and back office are then applied in explaining the location of Samsung＇s operating entities in china. By analyzing the spatial structure and locational principles of Samsung, a typical MNC in china, this paper aims to understand the internal operating mechanism of modern MNCs and then bring assistance to related policies to cope with those problems about MNCs that have attracted growing attention in recent years.

Methods of Studying Petroleum Systems in Residual Basins-A Case Study of Mesozoic and Palaeozoic MarineBasins in Southern china

引用

Acta Geologica Sinica(English Edition) 2002年第2期76卷 205-220页

作者： ZHAO Zongju, ZHU Yan, yang Shufeng, wang Genghai,XU Yunjun, FENG Jialiang and DENG Hongying {2. of Geoscience, zhejiang University, hangzhou 3.002., zhejiang hangzhou Institute of Petroleum Geology, hangzhou 3.002., zhejiang Zhou Jian Fei Zhenbi department of Geoscience Zhejiang University Hangzhou 310027 Zhejiang

Through an integrated study of Mesozoic and Palaeozoic petroleum geology insouthern china and a summing-up of the results of exploration, the authors tentatively put forward aset of methods of studying petroleum systems in modified residual basins or superposed basins. Itscore idea is to put emphasis on the study of the dynamic evolution of petroleum systems. Thetempo-spatial evolution, hydrocarbon-generating processes and hydrocarbon-generating intensities andamounts of resources in different geological stages of chief source rocks are mainly deducedbackward by 3-D basin modelling. The regularities of formation and destruction of oil and gasaccumulations are summarized by analyzing the fossil and existing oil and gas accumulations, thedirection of migration is studied by palaeo-structural analysis, and the dynamic evolution ofPalaeozoic and Mesozoic petroleum systems in southern china is studied according to stages of majortectonic movements. The authors suggest that the realistic exploration targets of Palaeozoic andMesozoic petroleum systems in southern china are secondary and hydrocarbon-regeneration petroleumsystems, while the existing primary petroleum systems are rare. They propose that the favourableareas for exploration of Palaeozoic and Mesozoic petroleum systems in southern china are the frontarea of the Daba Mountains and the steep anticlinal zone on the western side of the Shizhusynclinorium in northeastern Sichuan, the Funin-Yancheng-Hai'an-xinghua-Baoying area in the northernJiangsu basin, the Qianjiang-Xiantao-Paizhou-Chacan 1 well area in the southern part of the Chenhuarea of the Jianghan basin, the South Poyang basin in Jiangxi and the North subbasin of the Chuxiongbasin. This view has been supported by the discovery of the Zhujiadun gas field in the Yanchengsubbasin of the northern Jiangsu basin and the Kaixiantaixi oil-bearing structure in the southernpart of the Chenhu area of the Jianghan basin.

Stable Lagrangian numerical differentiation with the highest order of approximation

引用

Science china mathematics 2006年第2期49卷 225-232页

作者： wang xinghua CUI Feng department of mathematics Zhejiang University Hangzhou 310028 China Department of Mathematics Zhejiang University Hangzhou 310028 China

Some asymptotic representations for the truncation error for the Lagrangian numerical differentiation are presented, when the ratio of the distance between each interpolation node and the differentiated point to step-parameter h is known. Furthermore, if the sampled values of the function at these interpolation nodes have perturbations which are bounded by ε, a method for determining step-parameter h by means of perturbation bound ε and order n of interpolation is provided to saturate the order of approximation. And all the investigations in this paper can be generalized to the set of quasi-uniform nodes.
