日语自他动词的区别及其语义功能     

张丽芳 《乐山师范学院学报》2011,26(1):67-69

日语动词按其意义和用法可以分为自动词和他动词,其中有对自他动词是日语动词的独特现象。自动词和他动词在形态上要求不同的格助词,在意义上自动词强调客观结果和状态,他动词强调动作主体的意志。在与动词的体和语态的关联上,自动词和他动词呈现出不同的语义特征。  相似文献   

Teaching styles and conceptions of effective teachers: Tibetan and Han Chinese academics compared     

Li-fang Zhang 《Learning and individual differences》2011,21(5):619-623

The principal objective of this research is to ascertain if the “research–teaching dichotomy” as revealed in the relationship between conceptions of effective teachers and teaching styles among Han Chinese academics can be found among Tibetan academics. As a preliminary objective, this research examines the appropriateness of the Effective Teacher Inventory (Zhang, 2003) for evaluating Tibetan academics' conceptions of effective teachers and compares the conceptions of effective teachers between Tibetan and Han Chinese academics. The Thinking Styles in Teaching Inventory (Grigorenko & Sternberg, 1993) and the Effective Teacher Inventory (Zhang, 2003) were administered to 162 Tibetan academics. For the purpose of comparison, data from 93 Han Chinese academics in Zhang's (2009) study were integrated into the present research.The results warranted two conclusions. First, the Effective Teacher Inventory was appropriate for assessing Tibetan academics' conceptions of effective teachers; and there was no substantial difference in the conceptions of effective teachers between the two samples. Second, as it was among Han Chinese academics, the apparent “research–teaching dichotomy” was identified among Tibetan academics. Limitations and significance of this research are discussed and directions for future research are proposed.  相似文献   

紫外光诱导三角形银纳米粒子形成球形银纳米粒子及SERS研究     

施建珍  王玮  方靖淮  薛同莲  李雅丽 《泰州职业技术学院学报》2011,11(6):105-108

以聚乙烯吡咯烷酮为保护剂,制备三角形银纳米粒子溶胶。用紫外灯对三角形银纳米粒子溶胶进行光诱导实验。利用透射电子显微镜、紫外-可见吸收光谱和拉曼光谱仪研究了不同光照时间下的银胶纳米粒子的光谱特性和表面形貌,以PATP为探针分子检测银胶纳米粒子的表面增强拉曼散射光谱。实验结果表明：随着光照时间的增多,银纳米粒子溶胶颜色变化显著;紫外-可见吸收光谱吸收峰出现＂蓝移＂;透射电子显微镜图显示银纳米粒子由三角形逐渐转变成截角三角形银纳米粒子、球形银纳米粒子;表面增强拉曼散射的增强效应随着光照时间的变化逐渐减小。  相似文献   

Video retargeting using optimized crop-and-scale     

薛银珠  杜欢  刘志  张兆杨 《上海大学学报(英文版)》2011,15(4):331-334

Mobile devices are increasingly powerful in multimedia transmitting and browsing. However, the small screen and different aspect ratios of mobile devices lower visual quality while watching images or videos. Video retargeting is aim at fitting an existing video into arbitrary size and aspect ratio. Previous content-aware retargeting methods are mostly high computational cost, which limits their applications on the portable devices with low computation ability. In this paper, a new crop-and-scale approach is presented to adapt video to better suit the target display. We automatically find the optimal parameters of cropping window using the dynamic programming method, and then scale it to fit the target display. The cropping window can smoothly shift during a shot to follow the movement of important objects. The retargeting results using our approach introduce no deformation and jitter effects over the whole video. Experimental results show the success of our approach on adapting a variety of source videos to small display sizes.  相似文献

翻译中的“求同”与“存异”     

薛璟琰 《忻州师范学院学报》2011,27(6):71-72,122

翻译中要真正做到文化翻译的一一对应是不可能的。翻译中"求同"的原则适合以目的语文化为归宿,"存异"的原则适合以源语文化为归宿。翻译目的不同,翻译策略的选择是不同的。"求同"采用"归化"的翻译策略,"存异"采用"异化"的翻译策略,翻译策略的选择要根据文本的性质来定。关注意义而对形式要求不高的庄严性、科普性文体采用归化的策略,保持原文的真实性和原有风格采用异化的策略。但归化和异化两者不是互相对立,而是相辅相成、互为补充的。  相似文献
