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。

Bunya Koh and Akira Ifukube were among the most important Asian composers. At the beginning of their artistic career, they inspired each other, and learned from each other. Though they both studied in Japan, and dealt with nationalistic source material in a modern way, they were different in their pursuits of Nationalism and in their styles. Their efforts had gradually become part of the cultural tradition of the nation. Akira Ifukube's Nationalism started from the nationwide level, adapting the ancient Ainu hymn originated in his hometown, Hokkaido, Japan. After underwent the contemporary dynamism, he ended up in Japanese classical music, singing for Asian music.

江文也、伊部昭是亚洲重要的作曲家，二人在创作之初互相观摩、激，虽然在日本学习的环境相似，而且以较现代技法及民族素材创作，但「民族主义」的层面及民族性风格在追求方向是有同的，这些追求逐渐成为他们的文化记忆与文化传统的一部份；伊部昭「民族主义」风格转变，由「日本层面」推演至海道爱奴人「古歌咏的旋」风格，再由「现代主义」尝试之后，进而转向日本雅文化、歌咏亚洲的音。

On the other hand, Bunya Koh's Nationalism set out from an imaginary Taiwanese style. Later, being inspired by Alexander Tcherepnin, a Russian musician, to find out the national subjectivity, he adjusted Chinese style and wrote nostalgic Taiwanese music, returning to original purity from the complicated Modernism.

而江文也「民族主义」风格转变，由「想像中」的台湾风格出发，在俄国作曲家齐尔品的音观影响下，尝试找出民族主体性而转向中国风格，晚期乡愁般的台湾情怀，作品也由最初极为繁复的「现代主义」回到单纯真实。
