Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

我们以3-苯甲酰基-5-甲酰基中氮茚为原料，通过三碘化钐促进的aldol反应和Wittig反应制备了3-羰基-5-羰基乙烯基中氮茚，随后经低价钛还原偶联，没有生成正常的分子内羰基-羰基偶联产物，而是得到反常的羰基与α，β-不饱羰基的双键偶联产物，较高收率地得到了含多官能团的CycI[3，2，2]azine衍生物。

I at you of the article up expended for 3 years, in addition to learning to escape A form for a 60 cycle of sixty yearses, another of on having no acquisition, also useless you of overpraise in the method!

我在你的那些文章上耗费了3年的光阴，除了学了个60甲子遁甲表，别的一无所获，也没用你的方法中过奖（说实话，我还不会你的方法，问也问不完的）！

HCV is now know to be the major cause of parenterally transmittednon-A,non-B hepatitis.until the virus was characterized,diagnosis was made by exclusion of all other known case of hepatitis.

丙型肝炎病毒是目前所知为主要原因肠胃传染非甲非乙型肝炎，直到病毒的特点是，诊断作了排斥所有其他已知的情况下，肝炎抗体，丙型肝炎病毒被发现，在过去八成患者记载翔实非甲非乙型肝炎肝炎世界广泛流行的丙型肝炎病毒是0.2 %，献血达80 %和静脉其它途径如共用针头职业接触血液和血液透析，但在接近半数的丙型肝炎病毒感染的传播途径则不详。

The performance of these catalysts was similar to that in their methoxycarbonylation of pyrrole, suggesting that the catalyst system obeyed the same mechanism in the methoxycarbonylation of heterocyclic compounds.

这些催化剂的性能和反应规律类似于吡咯的甲氧基羰基化反应，意味着在杂环的甲氧基羰基化反应中，催化体系具有相近的反应机理，这有待于进一步的研究。

Well-known enemies like the Titanium Man and the Crimson Dynamo were considered, but finally the lesser-known Iron Monger, Obadiah Stane, was chosen as Iron Man's adversary (Stane, as well as possessing his own armor, is also a business contemporary of Stark).

著名的敌人，如钛甲人和绯红机甲，都在考虑范围内，但是最终名气较小的铁霸王，欧巴迪亚·斯坦恩，被选为了铁人的对手（斯坦恩不仅拥有他自己的盔甲，他也是斯塔克的经济合伙人）。

The results of the dissertation were concluded as follows:(1) It is essential to deposit a basic additive on the Mo-based catalysts for the synthesis of CH_3SH. The potassium-doped Mo-based catalysts exhibit the highest activity than that of the catalysts doped with the otherⅠA andⅡA group basic promoters. H_2-TPR and LRS characterizations suggest that the addition of a base leads to the transformation of octahedrally coordinated Mo to tetrahedrally coordinated Mo, thus leads to the split of low temperature reduction peaks. The interaction between the basic components and Mo lead to the formation of B-Mo interface phase, which are closely correlated with the formation of CH_3SH.(2) It has been found that Fe, Co, Ni and Te have evident promoting effects for the K-Mo/SiO_2 catalysts.

主要结果归纳如下：(1)在Mo基催化剂中，必须添加碱才具有可观的合成甲硫醇活性，在IA和IIA族元素中，K是最佳的碱促进剂，当K/Mo摩尔比为2，前驱体为K_2CO_3，采用共浸法制备的K-Mo催化剂活性最高。H_2-TPR和LRS表征显示，碱的加入导致表面八面体钼氧物种向四面体转化，催化剂的低温还原峰发生分裂，碱助剂与钼之间存在强相互作用形成了B-Mo"界面相"，该物种与合成甲硫醇密切相关。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
