从《骆驼祥子》英译本对引语模式的处理看小说风格的再现

引语模式是小说风格的重要方面。老舍在他的小说《骆驼祥子》中采用了以自由间接引语为主的多元引语模式,对于塑造人物的性格以及情节的展开起到关键的作用。自由间接引语效果的再现,直接关系到小说风格的传达效果。本文结合《骆驼祥子》的主题和人物性格,探讨了《骆驼祥子》中大量使用自由间接引语的原因,在此基础上,通过从四个英译本中随机抽取的几个例证,考察四位译者对自由间接引语的处理方式,探讨其在风格再现方面的得失优劣。最后,笔者试图得出这样的结论:译家的文体意识直接关系到文学译本的优劣,对于再现原著的文学性至关重要。2010年上海外国语大学校级规划基金项目“新时期中国现当代小说的英译”(项目编号:2010114021)的阶段性成

不同载体负载的cr基催化剂催化co2氧化异丁烷脱氢制异丁烯

The effect of supports (MSU-1,), gamma-Al2O3, AC (activated carbon), and MgO) on the catalytic activity of Cr-based catalysts was investigated for the dehydrogenation of isobutane with CO2. The catalytic activity was in the order of CrO,IMSU-1 > CrOx/Al2O3 > CrOx/AC > CrOx/MgO. The catalysts were characterized by N-2 adsorption-desorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and temperature-programmed desorption (TPD). The XRD results indicate that the active species of Cr are dispersed well on the supports. N-2 adsorption-desorption shows that the support MSU-1 has the largest surface area (804.2 m(2)/g), which results in excellent dispersion of Cr and highest activity. The XPS results reveal that Cr6+ is one of the active centers. The results of NH3-TPD indicate that catalyst activity is proportional to the amount of weak acid adsorption sites. As a result, the best support is the MSU-1 zeolite owing to its high specific area and a large amount of weak acid sites. The 59.2% conversion of isobutane and the 39.5% yield of isobutene are achieved on the CrOx/MSU-1 catalyst
