Sedimentary basins are where the products or erosion of the related reliefs *** sedimentary records preserved in the basins offer the possibility of quantifying the paleotopography z(x,y,t) at each point( x,y )of a given region at any time t in the past by using methods of mass balanced reconstruction(Hay et al.,1989,Métivier and Gaudemer,1997),The importance of paleotopography is on that atmospheric circulation models and the ocean circulation models which depend on them require knowledge of the topography of the land as an important input boundary condition which strongly affects the model output(Barron and Washington,1984,Ruddiman et al.,1997).Thus,a first step towards establishing paleoelevations is to reconstitute the history of sedimentary basins in terms of mass accumulation(Hay et al.,1989).This work reconstructs the space\|time depositional history and estimates the mass stored in the Hoh Xil basin,northern *** Hoh Xil basin,with an area of 101000km\+2.and an average elevation of over 5000m,is the largest Cenozoic sedimentary basin in the hinterland of the Tibetan *** the Early Eocene to the Early Miocene,a sediment pile of approximately 5 4km thick of fluvial mudstone,sandstone,and conglomerate and 0 3km thick of limestone was formed in the basin (Liu and Wang,2.00;Liu et al.,2.00).the mass estimate is derived from 2. measured field cross\|sections,with total thickness of 13479 *** results show that the Hoh Xil basin has undergone 7 stages of evolution from the Early Eocene to the Early Oligocene,with a period of no sedimentation during the Late *** Fenghuoshan Group was formed from the first four stages as 56 0～52.0,52.0～46 7,46 7～39 7,and 39 7～33 2.a ago,with the depocenter moving eastward and *** Yaxicuo Group was formed from the two next stages as 33 2.32.2.and 33 2.30 2.a *** Wudaoliang Group spread the entire basin during the last stage of ca.2. 0～16 0Ma ago,with its depocenter in the northern part

厦门大学学报（自然科学版） 2002年第S1期41卷 138-页

作者： HAO Jian-ping 1, XUE Qi 2. YU Yong-li 1 (1. Maintenance Engineering Institute, Shijiazhuang 050003, China 2. System Engineering Institute, Beijing 100101, China)

Maintainability is an important design characterist ic , and also is a design parameter. The essence of maintainability design is to ex pect and solve possible maintenance problems at early stage during product devel opment, maintainability must be designed into product simultaneously. But curren t maintainability methods do not support concurrent engineering. This paper anal yzes the deficiencies of existing maintainability technologies, and introduces t he concept of maintainability analysis visualization. The two major deficiencies are that maintainability analysis time lags behind product design, and the main tainability techniques do not accommodate modern product design concepts. After this, the infrastructure of maintainability analysis visualization system is dis cussed. The system are composed of four subsystems, they are product modeling, d isassembly process modeling, simulation and analysis, and user interface. Produc t modeling is accomplished with the capability of CAD system, disassembly proces s modeling is mainly a reason process based on assembly information. The system is integrated into AutoCAD so that designer can timely analyze their product des ign from the viewpoint of easy maintenance. Human model generation function, hum an task analysis function, tool analysis function, visibility analysis function is implemented, disassembly process planning function is still under developing.

An integrative model and analysis of cell cycle in fission yeast

Science Bulletin 2005年第17期 82-89页

作者： TENG Hu1, HUANG Xun1, XIU Zhilong1 & FENG Enmin2.1. Department of Bioscience and Biotechnology, Dalian University of Technology, Dalian 11602., China 2. Department of Applied Mathematics, Dalian University of Technology, Dalian 11602., China

According to the recent investigation on cell cycle of fission yeast, a mathematical dynamic model is for-mulated. Four cyclins, e.g. Puc1, Cig1, Cig2.and Cdc13, are investigated here. The interacting networks between the cy-clins and the process of cell cycle are mathematically de-scribed. The functions of these cyclins are particularly ana-lyzed. Comparison among different mutants indicates that the cyclins play an important role in cell cycle.

Climate change scenarios, predicted using the regional climate modeling system of PRECIS (providing regional cli-mates for impacts studies), were used to derive three-layer variable infiltration capacity (VIC-3L) land surface model forthe simulation of hydrologic processes at a spatial resolution of 0.2.° × 0.2.° in the Haihe River Basin. Three climatescenarios were considered in this study: recent climate (1961-1990), future climate A2.(1991-2.00) and future climateB2.(1991-2.00) with A2.and B2.being two storylines of future emissions developed with the Intergovernmental Panel onClimate Change (IPCC) special report on emissions scenarios. Overall, under future climate scenarios A2.and B2. theHaihe River Basin would experience warmer climate with increased precipitation, evaporation and runoff production ascompared with recent climate, but would be still likely prone to water shortages in the period of 2.31-2.70. In addition,under future climate A2.and B2. an increase in runoff during the wet season was noticed, indicating a future rise in theflood occurrence possibility in the Haihe River Basin.

通过研究Ca2.、Al3+、H+饱和的蒙脱石,Ca2.饱和的叶腊石和高岭石对水溶液中两种有机碱(甲基黄和S3307D)的吸附反应,证实了粘土矿物-有机碱吸附作用机制中表面酸碱反应的存在及其重要性.粘土矿物对有机碱的吸附能力为H+-蒙脱石 Ca2.-叶腊石>Al3+-蒙脱石 Ca2.-蒙脱石≈Ca2.-高岭石.通过测定悬浮液pH值和水溶液中矿物表面酸强度,判断吸附机制主要是由表面酸强度而非pH值所控制,即吸附反应机制主要为矿物表面酸位与有机碱之间直接的表面酸碱反应.水溶液中可能的粘土表面酸位为交换性Al3+、H+以及2.1型矿物表面不带电荷部分.

Al70-XSi30MnX (X=0, 3, 5, 7, 10, mol%) ribbons were prepared by melt spinning. A supersaturated solid solution of Si and Mn in fcc Al and some microstructures consisting of nano grains were obtained. Some alloys with nano-sized grains exhibited high discharge capacities and favorable cycle properties. The capacity of more than 400 mAh/g could be obtained in melt-spun Al67Si30Mn3 alloy after 2. cycles and more than 300 mAh/g after 40 cycles. Li/Si and Li/Al compounds in the anodes of pure Al and pure Si were not detected in Al-Si-Mn alloys inserted by Li. It is considered that the formation of the supersaturated solid solution and refinement of microstructures have prevented the alloys from the forming the compounds with superfluous Li. As a result, the electrochemical properties have been improved.

CENOZOIC LARGE-SCALE STRIKE-SLIP FAULT IN WEST YUNNAN, CHINA

地学前缘 2000年第S1期7卷 268-269页

During the collision between India and Eurasia, the continental compression and shorten is thought to be absorbed by the way of thickening of the Tibetan plateau crust and strike\|slip extrusion outwardly of blocks surrounding the Tibetan plateau. A series of models have been proposed recently, of which the most typical one is continental blocks extrusion by Tapponnier et al.. Virtually previous studies show that the Red River—Ailaoshan fault is the eastern boundary of extrusion Indochina displaced southward relative to South China about 2. Ma ago, and more, the western boundary of extrusion blocks is inferred to be Sijie fault in the eastern Burma. But the movement age of Sijie fault is around 13 Ma inferred from the age of Andeman Sea formation and different from that of the Red River—Ailaoshan fault. It is an important scientific problem where the western boundary of extrusion blocks is.
