We have synthesized 4,4'-dinitro-3 4''-dimethyl triphenylamine,(1), in 84% yield in an one-step condensation process between 3,4-dimethyl aniline and 4-fluoro-nitrobenzene. After the auto-oxidation of (1) and the subsequent hydrogenation of the nitro-groups, an AB2 type triphenylamine polyimide intermediate bearing two amine groups and one acid-anhydride group each on individual phenyl ring,{AB2 PI Intermediate}, was prepared successfully. The yields of the autoxidation and the hydrogenation steps are 81% and 90% respectively.

This paper includes several parts: first, some important concepts of the thesis have been defined, a theoretical overview of currency crisis has been finished; then, we have described the history of the international monetary system; later, three chapes have been arranged to discuss the mechanism of currency crisis under fixed and floating and intermediate exchange rate system respectively. The part of the fixed exchange rate system mainly includes the analysis of the collapse of the international gold standard system, the Bretton Woods system and the the European Monetary System; in the part of the floating exchange rate system, the volatility problem under freely floating exchange rate system has been studied; the part of the intermediate exchange rate system mainly includes the analysis of currency crises in regional dollar standard system and the currency board system. And finally, we have analysed the inevitability of the appearance of new type regional monetary cooperation patterns, and how these cooperations avoid currency crises.
本文主要包括这样几部分:首先,对论文中涉及到的重要概念给予界定,并对货币危机理论进行系统梳理;接着,按时间顺序从总体上回忆国际货币制度的历史演进;然后,用三个章节分别研究了固定汇率制度、浮动汇率制度以及中间汇率制度下货币危机的形成机理,其中,固定汇率制度下的货币危机主要包括国际金本位制度和布雷顿森林体系的崩溃,以及欧洲货币体系的瓦解;浮动汇率制度下的货币危机,则重点分析了自由浮动汇率制度下汇率的过度波动问题;中间汇率制度下的货币危机,分别分析了区域美元本位及货币局制度下货币危机的发生机理;最后,分析了目前新型区域货币合作模式出现的必然性,及各模式下如何规避货币危机。

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

It is confirmed that under the illumination of light the dark-adaptedBR is quickly turned into the light-adapted, and undergoes a photo-chemical cycle then through a sequence of intermediates of J, K, L,comes into a more stable intermediate-M state. M state relaxes to B state in about one hour. B state converts completely into D state after 24 hours. B state initiates the photochemical cycle under illumination, while it can transform into D state in the dark. So B state is a key intermediate in the BR photochemical cycle.
实验证实,样品受光照激发后很快从暗适应型经过光适应型进入光循环,经过一系列的光化学中间体到达较稳定的M态。M态经过约1小时热驰豫完全回到光适应型B态,B态再经过24小时缓慢热驰豫完全回到暗适应型D态。B态受光则进入光循环,不受光则转化为D态,从而认为B态是菌紫质光循环路径中一个重要的分支节点。
