This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。

Trust property,in the common sense,should undertake independent and limited liability for all its business activities.The institution of trust registration is to proclaim the confine of the liable property to the public,and so the registration is the premise of the establishment of such liability institutions.The content of the registration should be on the property easy to be ascertained.The efficacity of the registration is mainly about the proclaiming and defense to the public.

Simultaneously, tumoricidal activity of tyroserleutide against BEL-7402 cell line in vitro was observed hinger when compared with the control group(P.05).The inhibition effect of 72hrs was higher than 24hrs,48hrs,96hrs.And specially the high dosage of 160ug/ml can significantly inhibit growth of tumor cell by 19.36%. Tyroserleutide can activated PEM and marked enhance cytotoxicity andphagocytosis functions in vitro and in vivo. The OD values of cytotoxicity were observed hinger when compared with the control group(P.05).The cytotoxicity of macrophages activated by tyroserleutide against BEL-7402 and B16-F10 was 35.58%,61.2% in vitro and21.39%,47.63% in vivo. The cytotoxicity rate of nude mice PEM was 32.86%,73.07% in vivo. Furthermore, tyroserleutide alone could stimulated the production of IL-1B TNF- a and NO by M . Tyroserleutide and LPS could synergistically activated M producing more cytotoxicity effectors. Conclusion: Tyroserleutide had inhibition functions against hepatoma carcinoma .Its possible mechanisms were related to the affect that Tyroserleutide could inhibit tumor cell directively and induce tumor cells apoptosis or death effectively.

Nagadum has an inseperable relationship and interactive basis with school education, family education and social education. Chapter six mainly analyzes the current inheritage of Nagadum and its existing problems from the position that the realization of its educational funtion relies on its effective inheritage, it also provides the concept to rebuild the transmission of Nagadum. Chapter seven tries to analyze and reflect the current courses in national school education and its disadvantages of isolating from its native culture and living practice from the position that the realization of its educational function relies on the widely identification of national school education. It proposes that the essence of national education is "the education of national culture", the aquisition of native knowledge is obtained on the basis of practical mode of acquisition, hence the author tries to provide some constructive suggestions that school education in minority areas should return to native knowledge and culture, and the construction of the interactive relationship between schools and communities should be established.

The former is thought to result in the abstraction;the latter makes the relation disappear.Secondly,put forward my ownunderstanding of this relation,which should be understood from double meaning:the relation between individual being and the essence of society;the relationbetween individual and the society as a whole.Thirdly,analyse its form inreality from the association of substance and function to prove that it is asymbiosis in which both side depend on each other and create each other.Fourthly,work out a conception of neo-collectivism and attempt to provefrom several aspects on the basis of the understanding of social departmentologyin the view of symbiosis.

本文所做的工作主要是：（1）分析了目前在个人与社会之关系问题上的两种错误理解，即实体化理解和功能化理解，认为前者导致问题的抽象化，后者则在实质上取消了问题本身；（2）提出对于个人与社会之关系的理解，应当在两重意义上予以综合把握：个人存在与其社会本质的关系，以及个人与社会整体的关系；（3）从主体与关系相结合的维度分析了个人与社会之关系的现实形式，即是二者之间互相依存、双向互塑的共生关系；（4）在对社会本位论做共生论理解之拓展了的视界中，提出新集体主义的构想，并从多个方面进行论证。

mitochondrial dnais the only inheritant substance except for the nuclear dna in a euˉkaryon cell,which is related to the oxidative phosphorylation of a cell.mitochondrial dna is the important target of carcinogens and is vulnerable because of its structure and function.the mutation of mtdna could reduce the nomal respitation and release large quantities of ros,whichincrease the danger of cancer happening.so,mtdna has been thought to be involved in carcinogenesis and recently more and more studies in this aspect have comeout.in this paˉper,we review the researches for relationship among mtdna mutation and tumors in digestion system,woman system,head and neck,urinary systemand blood system.

线粒体dna（mitochondrial dna，mt dna）是真核细胞中唯一存在的独立于核dna之外的遗传物质，与细胞的氧化磷酸化功能密切相关。mtdna自身的结构和功能特点决定了它是致癌物作用的重要靶点，易受致癌因素的损伤而发生突变。mtdna的突变可削弱正常的呼吸功能，释放高水平的活性氧，进而增加肿瘤发生的危险性，所以mtdna被认为与肿瘤发生有密切关系。近年来，这方面的研究越来越多，本文现就mtdna突变与消化系统肿瘤、妇科肿瘤、头颈部肿瘤、泌尿系统肿瘤等实体瘤以及血液系统恶性肿瘤之间的关系作一简单的综述。
