ObjectARX技术在电网CAD中的应用

介绍了面向对象的设计思想和对象的抽象机理在电网CAD（PWCAD）系统中的应用以及ObjectARX编程技术。通过分析电网结构的知识特点入手，阐述了通过利用AutoCAD核心数据库的开放结构和ObjectARX提供的基类及类的继承、派生机制定义电力系统专业对象的过程，以及建模系统的数据交换技术，并给出了电力系统中元件类的具体定义方法，由此建立了PWCAD的对象模型。实现了电网CAD与外部数据库之间的数据交换，即图形数据库的一体化。     

渠道管理中的厂商与分销商的博弈分析

分销渠道管理中生产厂商与分销商的良好合作是进行优势互补、提高渠道竞争力和适应市场变化的有效手段。通过对生产厂商与分销商合作交易特征介绍和交易条件的假设，基于相互之间合作的关系建立混合博弈模型，并进行分析，找出影响双方合作关系的因素和实行稳定作的条件；然后，进一步对生产厂商与分销商的长期合作进行有限次重复博弈分析，找出影响双方合作关系的条件，最后，根据推论分析的结果，指出生产厂商与分销商建立良好的合作关系应采用的策略。     

45钢零件淬火过程温度场的ansys模拟

ansys有限元软件在温度场的模拟过程中，很好地结合了材料变温过程材料热物性参数的变化，特别适用于钢件淬火过程温度场的准确计算。通过利用ansys有限元分析软件对几何外形复杂的45钢零件淬火过程温度进行有限元模拟，得到了零件温度随淬火时间的分布关系。模拟结果与实际过程一致，且运算速度较快，适用于淬火液的选取及淬火工艺的优化，并为精确计算淬火过程中的热应力、残余应力做好了准备工作。

师资培训工作是课程改革实验工作的关键。其中，观念的转变是教师培训的核心内容，为了适应新课程，数学教师的数学观、数学学习观、数学教学观、数学评价观都需要做很大的调整。同时，数学教师的知识面和能力也需要拓广，促使教师改变的培训方式是多样的，案例加反思是具有代表性的一种方式。     

A UDDI Based Shared Resources Management Mechanism in Virtual Enetrprises .

Service and information resources are two kinds of major shared resources in virtual enterprises, where, service resources include third party‘s service resources and enterprise‘s legacy service resources, and information resources include database resources and file resources. Since service and information resources have distributed, autonomic, remotely bound as well as some other similar characteristics, an implementation mechanism on managing shared resources based on UDDI are presented. XML instances are used to describe resources authorization information, WSDLbased special XML instance represents information resource metadata, and these XML instancesare referenced by tModel for realizing the purpose of managing shared resources metadata based on UDDI.     

Contributions of different land cover types in Otindag Sandy Land and Bashang area of Hebei Province to the material source of sand stormy weather in Beijing

Different land cover types in Otindag Sandy Land and Bashang area of Hebei Province are linked to a material source of sand stormy weather in Beijing based on results of field vegetation and soil survey and laboratory works. Results of grain size analysis show that dust release potential in per unit area of moving sandy land is small,while lowland meadow and meadow steppe in stony hills have high potential of releasing dusts in per unit area during sand stormy weather occurrence. Further considering the effects of vegetation, it is inferred that the moving sandy land served as a material source of past dust storm and the possibility of dust release in per unit area is low in current time.Typical steppe in stony hills is undergoing desertification and its dust release possibility in per unit area is high. Farmland has strong potential of release dusts when they are ploughed in spring, but a large amount of therophytes grow and thus prevent dusts from release when cultivation was terminated.Potentials of dust release in per unit area in fixed sand dunes,stony mountain meadow steppe and low land meadow are lowdue to high cover of perennials. Sand dune reactivation and desiccation of lakes and lowlands under estimated future climatic change will make them serve as a future material source of sand stormy weather.     

Evolution of the South China Sea and monsoon history revealed in deep-sea records

As the third summary report of ODP Leg 184 to the South China Sea (SCS), this paper discusses the evolution of the East Asian monsoon and the SCS basin. A multi-proxy approach, involving geochemistry, micropale-ontology, pollen and other analyses, was adopted for reconstructing the evolutionary history of the East Asian monsoon, which was characterized by a series of paleo-climate events especially at 8, 3.2, 2.2 and 0.4 Ma. The new record indicates similar stages in the development of the East and South Asian monsoons, with an enhanced winter monsoon over East Asia being the major difference. The rich spectrums of monsoon variability from the southern SCS also reveal other characteristic features of the low latitude ocean. Evidence for the evolution of the SCS includes the hemipelagic Oligocene sediments, implying the existence of deep water environments during the early seafloor spreading stage of the SCS basin. The four major unconformities and some remarkabl ediagenetic features in upper Oligocene deposits indicate the strongest tectonic events in the region. From a careful comparison of lithologies and sedimentation rates, we conclude that the prominent differences in sedimentary environments between the southern and northern SCS were established only by ～3 Ma.
