Reaction of 5'-O-p-methoxytrityl-thymidine with 1, 1'-carbonyl-diimidazole gave the 3'-O-carbonylimidazolide, which was condensed in high yield with 3'-O-protected thymidine to give a dithymidine carbonate. In the same way, we obtained the protected trithymidine dicarbonate. After deprotection, we obtained quantatively the trithymidine dicarbonate.By the same stratagy, we completed the synthesis of dithymidine sulfite.It was shown that allyl can be used as a good protection group for hydroxyl of ribose in the synthesis of oligonucleotides consisting in some unstable nucleotide analogues.

我们在第一部分工作的基础上，以烯丙基作为3'-OH的保护基合成了保护的三胸苷碳酸酯以及二胸苷亚硫酸酯，用我们所得的脱保护条件进行了脱保护研究，得到了三胸苷碳酸酯以及二胸苷亚硫酸酯，并研究了它们合成中的一些化学问题，结果表明：烯丙基能很好地运用于这两类寡核苷酸类似物的合成中，其脱保护条件为中性，不会影响碳酸酯键及亚硫酸酯键。

It's warning and outcry for mediocrity of human society by the superiority.Under the surrounding, The library can put a good equitant development into execution dependent upon whether the leader have a "sage jewel" of scientific decision making to understand and exert it's great signification poignantly.He delve library science and acquaint with professional skill, we can get a lot of practical experience from ancientness and today,Chinese and foreign. At the present time,run back over historical development of libary's management, getting a realization on property of common service and roles definitely.

在这样的大环境下，任何一个公共图书馆能否实现跨越式良好发展，这就要看领导者是否能以科学决策理念为&法宝&，深刻理解科学决策的重大意义并能在理论和实践创新中很好地掌握和运用决策理念的主要内容；是否能在图书馆学科理论研究的工作实践中，以图书馆学科体系为科学决策的理论基础，深入了解和研究图书馆学的形成和发展史、学科体系及分支学科、研究方法及其前景展望等，从而为科学决策在本专业学科领域的研究创新打下坚实的理论基础；是否能通过纵横分析人类文明历史进程中公共图书馆的基本职能及其演变过程，更加明确其职能的公益性质，从而树立起以最大可能实现公共图书馆的职能为成功决策的实践标准。
