The mobile search, a combination of a web search engine and a mobile communication system, is viewed as the most influential application in the 3G era. Therefore, mobile search service providers are eager to know which factors most influence user acceptance of mobile searches. Based on the characteristics of mobile searches and a review of previous information technology acceptance research, this study integrates the task technology fit model and the unified theory of acceptance and use of technology model to develop a mobile search acceptance model and empirically tests this model. This study finds that, for mobile searches, the performance expectancy, social influence, and perceived cost all significantly influence use intention and the performance expectancy increases with the increasing user’s experience and higher task technology fit degree. The effort expectancy is found to not affect the use intention of mobile searches and the users’ gender does not have a significant moderating effect on the use intention. The results are then used to develop suggestions for mobile search providers to promote their application and development. 相似文献

性能分析是电机优化设计的基础,由于非正弦供电多相感应电机稳态性能分析计算远比传统三相感应电机复杂,进行相关研究则具有理论意义与实用价值.在3次谐波注入的非正弦供电多相感应电机中,以基波等值电路与3次谐波等值电路为计算工具,考虑气隙磁场的非对称分布性并用拓展分布磁路法计算基波与3次谐波感应电动势,通过3层迭代计算出给定稳态运行工况下的基波与3次谐波电流等变量进而得到电机的性能指标,分析中强调了对节点气隙磁密的内层迭代过程与对激磁电流的中间层迭代过程不同于传统三相感应电机相应迭代过程的特点.以非正弦供电十五相感应电机原理样机为例,分析了不同稳态工况下的运行性能,计算结果与实验结果相互吻合说明了分析计算方法具有高的准确度. 相似文献
