Through discussing such core technologies in the automatic processing of chinese information as automatic word segmentation , feature selecting and automatic representation of texts , the thesis makes some improvements and perfection on the current methods of automatic word segmentation and text space reduction of chinese texts , therefore improved their efficiencies and effects . with regard to the methods of text classification , the paper introduced two supervisory automatic classification methods of chinese texts based on multi - classification , i . e . fuzzy clustering and boosting , which settled the problem of low percentage of recall . through comparing the results of experiments with the two methods , an automatic classification system of multi - classification texts is constructed based on the boosting method , which received good effects in application and provides a good resolution to the problem of real - time classification of information 通过对汉语信息自动处理中自动分词、特征提取、文本自动表示等核心技术讨论，对目前汉语文本自动分词和文本降维方法中的不足和缺陷作了改进，提高了分词和文本分类的效率和效果；在文本自动分类方法上，介绍了两种有监督的基于多类的汉语文本自动分类处理方法? ?模糊聚类方法和boosting方法，解决了实践中文本分类查全率不高的问题；通过对两种方法的实验比较结果，构建了基于boosting方法的多类文本自动分类系统，在实际应用中收到了良好的效果，较好的解决了信息的实时分类问题。
A virtual reality system describing the method of storages and calculations for the plane model and the curving model has been designed , which not only rectifies the distortion of model and the abnormity of texture mapping , but also presents a storage pattern of the complex 3d model on internet with less data streams 为了在互联网和个人计算机平台上模拟复杂的三维模型和自然景观，解决三维模型由于动态层次划分技术( lod )引起的外形失真和贴图映射异常，提高场景渲染的效率和效果，本文设计了一个虚拟现实仿真系统。
Management control system ( mcs ) is comprised of a series of elements and its purpose is to improve the effect and efficiency of management to make the system run well , we must think it seriously that which variables are the key thing to be controlled , what kind of criterion is the fit measure , and what means is the effectual way to realize the purpose 管理控制系统是由一系列管理控制系统要素组成的用以落实组织战略目标、实现组织经营管理活动的效率和效果的有机整体。要想真正使这一有机系统有效发挥作用，就必须考虑选取哪些变量为关键控制变量、应用何种标准更为适合、采用哪种手段能够奏效，这对于不同时期、不同国家、不同组织背景的组织来说不能一概而论，它极大程度上取决于企业的内、外部环境。
Build partnership with those who have good job reference , high reputation and capability , and provide quality products as strategic confederates . it management should be established . it shall be used to process the information from the sources outside the procurement and supply departs so as to obtain and transmit out the information from the sources beyond the procurement department , resulting in high efficiency and good effectiveness in procurement 实施战略采购应该做几个方面的工作是：实施供应商管理，进行供应商评审，对现有供应商进行绩效考评；企业还要根据对供应商业绩审核，优选出一批信誉好、生产能力强、产品质量高、战略思想和企业相似的供应商，和它们缔结战略同盟，结成战略伙伴关系；建立适合企业运作的信息系统，以处理来自于采购与供应职能部门以外的信息流入，产生为采购部门以外的其他职能部门和机构所需的信息流出，进而提高采购工作的效率和效果。
