STUDY ON POLYPYRROLE-VISCOSE CONDUCTING FIBER

The conductivity of Polypyrrole-viscose conducting fiber prepared with author's method can be shown up to as high as 2.106x10~(-2) S/cm. The main factors influencing the conductivity are the concentration of FeCl_3 used as dopant and initiator, the treatment time of viscose fiber as base material in FeCl_3 solution, temperature and polymerization time. It is found that the orientation and crystallization degree of viscose fiber keep constant before and after conducting treatment and the mechanical properties of conducting fiber is the same as that of base material. In addition, the distribution of polypyrrole in viscose fiber, and its effect on the conductivity were investigated in details by TEM.

塔里木-中朝板块北缘的志留纪岛弧公婆泉群火山岩地质地球化学及构造意义

公婆泉群位于北山中部，可分为：北、南两带。南带为弧后盆地玄武岩-安山岩组合，北带为岛弧火山岩组合，西段窑洞努如为火山角砾岩和熔火山角砾岩组合，中段公婆泉一带为玄武岩-安山岩-流纹岩-粗面岩组合，东段东七一山地区为玄武岩-安山岩-流纹岩组合。岩石组合，地球化学综合分析认为，公婆泉群是中-晚志留世哈萨克斯坦板块俯冲与塔里木-中朝板块的产物。岛弧西段窑洞努如位于近大陆或者在水下陆壳。公婆泉位于近海沟陆壳，而东七一山则远离海沟，是在洋壳的基础上发育的。说明塔里木-中朝板块是一个统一的板块，同时在早古生代存在哈萨克斯坦板块向塔里木-中朝板块的俯冲。

New geological evidence of crustal thickening in the Gangdese block prior to the Indo-Asian collision

Recent mapping in the Gangdese block has revealed many leucogranites that are similar to those in the High Himalaya. These leucogranites formed at ～140 Ma as indicated by monazite Th-Pb ion-microprobe dating and cooled at ～130 Ma as indicated by muscovite ^40Ar/^39Ar dating. In conjunction with previous structural and paleogeographic studies, the new data indicate that the Gangdese block underwent crustal thickening and associated exhumation during ～140—130 Ma. In this regard, the southern margin of Eurasia continent was comparable to the modern South American Altiplano-Puna plateau, the prime example of active ocean-continent subduction and associated thickened crust. Specifically, the early stages of crustal thickening and uplifting of the Gangdese block may result from subduction of the Neo-Tethyan Ocean. If the Tibetan Plateau would form by accretion of a series of blocks with thickened crust, an elevated topographic plateau similar to the Altiplano-Puna plateau had formed before collision between the Indian and Eurasian plates. Then the Tibetan Plateau would have quickly thickened, uplifted, and begun to extend soon after onset of the collision. Thus, the deformational mechanism of the Tibetan Plateau is not distributed shortening, but rather concentrating deformation within regions of thin crust between the accreted blocks.
