Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly, due to the formation of blackcoal and highly-metamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

以煤、油、气共生的辽河盆地东部凹陷和我国首次在矿井中发现、研究、开发煤层气藏的阜新盆地王营井田为例，系统地阐述了火山活动在古近系沙河街组三段对褐煤、长焰煤和气煤在平面及垂向分布的控制，进而导致各赋煤区气源条件的不同；估算了王营井田在区域深成变质过程释放甲烷气的基础上，接触变质作用所形成的附加甲烷量；指出由于岩浆侵入形成了天然焦和高变质裂隙煤，使煤层物理性质及储集能力发生了大的变化；强调了岩墙等不同产状的岩浆侵入岩体对煤层气的封闭作用。

This thesis consists of four parts as follows: Part I: ReviewThe purpose of the present review is to summarize the organic chemistry of polyvalent iodine compounds regarded as Chlorides, Fluorides, Oxidize reagents in the field of organic synthesis, especially focus on their synthetic application and space structure, there are lots of reaction examples to illustrate the incomparable merits of organic polyvalent iodine compounds in the synthesis of some drugs and natural products.

本论文由以下四部分组成：第一部分：文献综述本部分比较全面地回顾了有机含碘化合物作为氯化、氟化、氧化试剂在精细有机合成中的应用，主要针对含碘试剂的合成及其结构做了比较详细的综述，并且列举了大量反应实例引证了这种类型试剂在药物及天然产物合成方面具备的优势。

As an ideal prime immunization vaccine,the DNA vaccine has the advantages of high purity,continuous expression of antigens with low dose, repeatable immunization and inducement of memory CTL with high titer.Similarly, recombinant virus can not only highly express the target antigen,simulate the inducement process of virus infection on body immunity,and induce various cytokines,but also be beneficial to the interaction of high-affinity antibodies with T cell receptors,and the generation of Th1 reaction and CTL reaction.

DNA疫苗抗原纯度高，持续表达低剂量的抗原，可多次重复免疫以及诱导高效价记忆性细胞毒性T淋巴细胞反应，是理想的用于初次免疫的疫苗；重组病毒能高效表达目的抗原，模拟病毒感染诱导机体免疫的天然过程，能诱发多种细胞因子，而且有利于高亲和性抗体和T细胞受体的选择，可以有效地产生Th1型和CTL反应。

The Nature of Antibodies and the Immune Response in Rainbow Trout.

抗体是由抗原免疫后产生的，与某一抗原专一性地结合，特异性程度高；而凝集素是天然存在的，不需经过免疫而产生，能与多种抗原发生凝集反应，具有非特异性。
