This paper introduces the background knowledge of heterogeneous data integration, as well as the knowledge of data integration. On the basis of the above, The author develops an ontology-based Heterogeneous data Integration prototype system, expounds the main framework and essiontial technology. Then the paper introduces its work in detail: it explains the very significance of using ontology as an comon semantic description and an global query model ,and illustrates the reason fo adopting LAV method ; then it builds the formal representation of the mapping between ontology and data resources, applies OWL to describe the ontology and the mapping ; defines a query language named by DIQL to query on our integration system , and supply the detailed arithmetic of reolving partial binding of LAV method、locating of data sources and query rewriting,etc. Finally,the paper demostrates and proves the result of research by examples .

本文介绍了目前异构数据集成的研究现状以及数据集成和本体的相关背景知识，并在此基础上设计开发了一个基于本体的异构数据LAV集成原型系统，同时对原型系统的总体框架、关键实现技术分别做了讨论：首先阐述了将本体作为公共语义描述和全局查询模型的意义，给出了采用LAV集成方案的理由，然后规定了本体和数据源间映射的形式化表示方式，采用能结合描述逻辑和框架系统的优点、适合于半结构化环境的OWL表示本体和映射；其次定义了一种针对集成系统的查询语言DIQL，并在此基础上给出解决LAV部分绑定问题、数据源定位以及查询重写的算法；最后在原型系统的基础上，通过实例验证本文所提方法的可行性。

This paper analyses the different influence on the fundamental matrix by the different matched points in images and theweighted factor is introduced to express the distance between the matched point and the epipolar line which has the obvious geometry meaning.

分析了图像匹配点对基础矩阵的不同影响，引入具有明显几何意义的匹配点到对极线的距离作为匹配点的加权因子，将匹配点集合看作随机变量并将加权因子作为匹配点的概率分布。在此基础上对原始图像数据进行归一化处理，利用8点算法得到基础矩阵。

Finally, we show that the matching performance can be improved by combining the decisions of the matchers based on complementary (minutiae-based and filter-based) fingerprint information.

最后， 我们表明，匹配性能可提高合并决定的基础上补充matchers （细节为基础，筛选为基础）的指纹信息。

After the evaluation targets and their wights are decided, through the investigation, calculation, evaluation and comparison for 534 enterprises, the paper proves that; the technical basis of joint adventures is better than that of other enterprises in our country generally.

在确定了评价指标体系及其权重的基础上，通过对534个企业的调查、计算、评价及比较分析，从实证角度得出基本结论为：总体上我国合资企业技术基础高于其它企业，但在技术创新能力及投入上比其它企业无明显优势，合资企业对我国工业总体技术水平的直接影响主要是通过具有相对较高技术基础的合资企业经济总量在全部工业中的比例的提高引起的，而非合资企业存量技术素质提高的结果。

The groundwork of this text is as follows:In understanding the graphic presentation characteristic of the construction drawing of the building, foundation of content. At building the semantemes of construction drawing, building construction drawings understanding tactics and content gone on detailed analysis understanding. Have laid a good foundation for the following understanding of the construction drawing; According to the expression characteristic of the construction drawing, utilize the technology of OOP, Adopt C ++ language and draw the level models of fire control feature; It carries on deep analysis to DXF file format give and a method of read DXF file. On the basis of reading DXF file and familiar with understanding to the form of DXF file, study to the pattern recognition methods of fire control facility.

At first, the rought C〓F〓 mixed gases are obtained by pyrolysis process of R22. A experimental pyrolysis device is designed and made by ourself. The optimum operating conditions are offered in the paper. Secondly, the much efforts is on the synthesis of R134. After through the discussion of basic thermodynamics and kinetics, selecting and preparating catalyst, it is possible that the synthesis of R134 by pyrolyzed gases hydrogenation. Base on the character of catalytic process, the kinetics equation about C〓F〓 catalytic hydrogenation is established. The rate constant of the reaction is obtained through experiment data regression. In order to achieve higher yield of R134, some optimum technological conditions is determined.

论文首先对R22裂解制成四氟乙烯混合原料气的裂解过程进行了讨论，自行设计和制作裂解反应装置，并确定裂解反应的最佳操作条件；然后，重点对R134的合成进行基础研究，分别从热力学和动力学的角度探讨以含四氟乙烯的R22裂解混合气为原料合成R134这一全新工艺的可能性，选择和制备加氢催化剂，根据催化过程特点建立四氟乙烯催化加氢反应的总包动力学方程，并在此基础上自行设计和制作中试合成装置，获得了以裂解混合气为原料合成R134的最佳工艺条件，为R134的工业化生产提供了必要的理论依据和实验基础。
