摘要：With the continuous improvement of the train speed, the dynamic environment of trains turns out to be aerodynamic domination. Solving the aerodynamic problems has become one of the key factors of the high-speed train head design. Given that the aerodynamic drag is a significant factor that restrains train speed and energy conservation, reducing the aerodynamic drag is thus an important consideration of the high-speed train head design. However, the reduction of the aerodynamic drag may increase other aerodynamic forces (moments), possibly deteriorating the operational safety of the train. The multi-objective optimization design method of the high-speed train head was proposed in this paper, and the aerodynamic drag and load reduction factor were set to be optimization objectives. The automatic multi-objective optimization design of the high-speed train head can be achieved by integrating a series of procedures into the multi-objective optimization algorithm, such as the establishment of 3D parametric model, the aerodynamic mesh generation, the calculation of the flow field around the train, and the vehicle system dynamics. The correlation between the optimization objectives and optimization variables was analyzed to obtain the most important optimization variables, and a further analysis of the nonlinear relationship between the key optimization variables and the optimization objectives was obtained. After optimization, the aerodynamic drag of optimized train was reduced by up to 4.15%, and the load reduction factor was reduced by up to 1.72%.

摘要：动漫品牌建设对于动漫产业的发展具有重要意义。由于我国动漫产业尚处于追求量化的初级发展阶段,对品牌建设认识相对滞后,动画片产量高,知名品牌少,产业发展面临困境。本文在动漫产业转型升级的大背景下,从"明星制"角度探讨动漫品牌建设,分析"明星制"在动漫品牌建设中的类型、手段以及作用,提出通过"明星制"效应来推动国产动漫产品的品牌打造,对我国动漫品牌建设具有一定的启示作用。

摘要：双关是类似性修辞中最具创意感和趣味性的解决手段。在标志设计中常采用双关修辞以获得多重意义。当前双关修辞理论较为笼统,需要更进一步的类型划分。文章分析了一系列双关型标志,对其中本体与喻体符号的意义来源特征进行剖析,以管窥其符号替换与结合过程中的修辞动因;总结出更细分的双关修辞子类型,提出了在标志设计过程中使用双关修辞进行图形创意需要遵循的要点。

摘要：2009年国家推行的"新农保"制度是实现农村居民老有所养的重要基础性工程。本文利用中国老年健康影响因素跟踪调查2008—2011年两期面板数据,使用倾向分值匹配基础上的倍差法等方法,全面评估了新农保对农村居民养老质量的影响。结果显示,尽管实施时间不长和保障水平较低,新农保仍然在一定程度上提高了农村参保老人的养老质量。在养老质量均等化方面,新农保显著提高了西部地区老年人的养老质量,但加剧了不同收入组别农村老年人的养老质量不平等,现有农村老年人之间的养老质量差距也没有显示出缩小的迹象。因此应努力提高新农保的保障水平,促进农村老年人养老质量的提高,并通过合理的制度设计,推动农村居民养老质量的均等化。

摘要：With the rapid development of China film industry, more and more people are willing to go to the cinema to feel rich film culture, at the same time for the movie has also been seen the movie characters, including clothing and some other relative derivatives have higher requirements. Thus the birth of film art image derivatives, with the continued rapid development of film technology and film art, film art derivatives with 3D, 4D will be the future of film art image derivatives success ＂interview＂ has become a new economic growth point China film, its development prospects are very impressive. According to market research and analyse, through the research and analysis of 3D MAX movie derivatives as an example, from the aspects of brand image positioning and design of more specific design and research of film art image derivatives, thereby to strengthen and promote the combination of film technology and art products, and ultimately promote the rapid development of film art derivatives.
