While library resource sharing is shifting to the new networking environment era, it is also in face of a lot of new challenges and"Access versus Assets"is becoming the new theme of the resource sharing in this new networking era, based on this point this thesis studies the development and the transformation of the resource sharing both in practice and in theory in the networking environment, particularly focus on a serial of issues, including the construction of resource sharing system, digital information resource, digital library, interlibrary loan, document delivery service and collection development etc. The writer also analyzes the coexsitence of the traditional resource sharing and modernizational resource sharing and the relationship between them in 21st, explores the revolutionary changes of resource sharing as the"Assets"model is driving to the"Access"model, discusses the development of specific collection for a single library and how to construct a seamless integrated information resource system in the networking environment, systematically studies and introduces the new organization model of resource sharing, especially emphases that document delivery is the key of the success in resource sharing, and finally tries to outline the main trends which will influence resource sharing.

In chapter one,we discuss tournament matrices that can not end in tie and theyare(0,1)-matrices,we first obtain a better lower bound for the number of regulartournament matrices,then we discuss the payoff matrix of tournament matrix,obtainsome properties of positive tournament matrices,a correlation between the spectralof a tournament matrix and its payoff matrix.We find serveal conditions that areequivalaent to a tournament matrix having 1 as its a eigenvalue.
第一章讨论不允许平局的竞赛矩阵-(0,1)-矩阵,得到了正则竞赛矩阵数目的一个下界,它改进了文献〓中已有的结果;在文献〓的基础上进一步讨论了正竞赛矩阵的性质,给出了利用已知平衡向量构造新平衡向量的方法;讨论了竞赛矩阵和它的支付矩阵的特征值之间的关系;指出了文献〓中的一个错误,回答了文献〓中的一个公开问题,得到了整数1为竞赛矩阵的特征值的充要条件及这种矩阵的谱根与得分向量之间的关系。

Naturally,we confront with such a problem:can we generalizethe systematic work on the classical boundary value problem for analytic func-tions and singular integral equation to Clifford analysis?And so this problemhas especially theoretical and practical meaning,and naturally this problem hasbecome a common hot topic for mathematicians at home or abroad.
其结果在一定程度上推广了一些经典文献的结果,取消了这些在经典文献结果中对s=0或s=n的条件限制,需要指出的是,据作者所知,到目前为止,本文也是第一次系统而又比较深入地研究了取值在泛Clifford代数〓上的超复函数的性质,并获得了比较系统而又深入的结果;另外,本文还对Clifford分析中的某些比较特殊的Riemann边值问题与奇异积分方程做了一定程度的研究,由于文中所用的方法较曾经出现的文献而言有着根本的改进,因此,本文去掉了从前在这一问题的研究过程中所做出的一些不必要的条件限制,从而使得在比以往条件更弱的情况下,获得了比以前文献中更多的结果。

Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).
DMAE·NHS的合成是本论文的关键和难点,我们对文献方法进行改进:文献方法用氢氧化钠与3,5-二甲基-4-羟基苯甲酸反应制得3,5-二甲基-4-羟基苯甲酸钠,再用3,5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3,5-二甲基-4-羟基苯甲酸苄酯,我们用氢氧化钾代替氢氧化钠,使合成取得成功;在合成2',6'-二甲基-4'-苯基-吖啶-9-甲酸酯时,文献方法对粗产品进行两次硅胶柱层析纯化,第一次柱层析用氯仿/乙酸乙酯(4∶1,V∶V)作溶剂和淋洗剂,第二次柱层析用己烷/丙酮(2∶1,V∶V)作溶剂和淋洗剂,按照文献方法得到的不是所需要的化合物,我们只进行第一次柱层析纯化,然后用己烷/丙酮(2∶1,V∶V)进行研磨,过滤,洗涤,除去溶于己烷/丙酮(2∶1,V∶V)的部分,得到所需要的产品。
