These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

鉴于有机铁硫原子簇化学在基础理论发展和应用方面的重要意义，因此我们开展了这一课题的研究，并取得以下主要成果： 1、本文共合成了51个新有机铁硫及含钴碳簇基的有机铁硫原子簇配合物，除用元素分析，NMR，IR，MS法表征其结构和构象外，还用X-光衍射技术测得四个代表性配合物的单晶结构和构象； 2、我们业已发现炔基Grignard试剂同〓可形成一种&开环&与&闭环&中间物的平衡混合物，研究该平衡混合物同各种亲电试剂的反应； 3、研究发现了一种可高产率地形成〓含〓四配位硫挛合簇的新化学反应并对此反应提出了—种有趣的反应机理； 4、首次由1，4-二溴丁烷双Grignard试剂与〓制得一种新型铁硫簇双硫阴离子活性中间体，并进而研究了它的亲核反应性能； 5、找到了通过〓的光化学反应来合成簇合物〓-〓的一条有实用价值的新路线。

The present dissertation reviews the total synthesis of biotin, particularly on Hoffmann-La Roche\'s Lactone-Thiolactone approach. The Lactone-Thiolactone approach is presently the most competitive commercial route, which gives an excellent illustration of the gradual construction of the functionalized skeleton with the simultaneous solution of the stereochemical issues in a minimal number of steps.In 1970, Gerecke etc. of Roche Corp.

论文对生物素全合成的文献进行了综述，重点讨论了目前工业上最有竞争力的内酯—硫代内酯路线，展示了生物素是如何以最少的步骤去逐步构建目标产物的官能团骨架并同时解决立体化学问题的。1970年，Roche公司的Gerecke等报道了一条通过手性内酯，以较高收率并保持构型得到手性硫代内酯，从而直接合成d-生物素的方法后，该中间体内酯(3aS，6aR)-1，3-二苄基。

Hamstring flexibility enables easy high steps and wider stems. Good stemming technique allows you to rest and relax in the middle of hard climbs, which in turn keeps you loose and unpumped.

腿筋的柔软度可以使脚提更高或张更开，好的支撑技巧可以使你在困难路线的中间休息放松，肌肉就不会僵硬或充血。

With different culture background, formed two different ferment technology,course mixed ferment and pure-blood ferment, mixed ferment was provided with the quality of multiple strain accretion, enzyme system mutual complementarity, simplified equipment, suited to produce composition complexity and exigent flavour traditional zymolytic food of our country,pure——blood ferment had the quality of strain singleness,rare pollution, suited to produce composition singleness,exigent puritg alcohol and monosodium glutamate.

中西方文化底蕴不同，形成混含发酵与纯种发酵两种不同发酵工艺路线的历程。混合发酵具有多菌共生，酶系互补，省工节能，简化工艺设备，克服中间生成物浓度过大的特点。宜于生产成分复杂，风味要求高的我国传统发酵食品，纯种发酵基质，菌株单一，污染少，宜于生产成分单一，纯度要求高的酒精，味精等产品。

Jim Hightower, a populist pundit, once jeered that "There's nothing in the middle of the road but yellow stripes and dead armadillos."

民粹主义者权威人士JIM有一次戏称道&路的中间什么都没有，除了黄色的马路线与死的犰狳&。

After feeding, the volume of material roll of a central location that is, the business card printing and membership card making location, because this machine is affixed with a deviation, version, and so on are in sub-subparagraph to the central axis as the base, the material should be in strict accordance with our equipment for each feed routes through the guide roller is, put to paper machine for printing paper smooth and adjust the tension and cause to be printed materials subject to certain harmoning tension control in order to ensure the rectification of overprinter precision, adjustment, so that the material in the press and printing center position, to ensure that the rectification action ofsmell is correct.

上料卷之后，料卷的中心位置也就是制卡和会员卡制作位置，因为贴版纠偏、模切、分节等都是以中心轴为基准的，被印材料应严格按照本台设备的送纸路线穿过各个导纸辊、穿纸后可开动机器让被印材料送纸平稳，调节张力，使被印材料受到一定的平稳张力控制，才能保证套印精度、调整纠偏，使材料在印机及印版中间位置，以确保纠偏动作的灵敏无误。
