摘要：压电水声换能器是一种既能作为驱动器又能作为传感器工作的水下探测装置。准确预测其在嘈杂水下环境中的声学特性对设计出坚固耐用的换能器是十分重要的。有限元方法对分析换能器在不同环境中的各种性能十分有效和实用。建立了一种Tonpilz型换能器的二维轴对称有限元模型,设计了基于有限元方法的程序,对其进行了动力学分析,包括模态分析和谐响应分析等,获得了一些声学特性。该程序分析的结果与ANSYS软件分析的结果显示出较好的吻合性。

摘要：色彩通过其独特的图像、功能和情感成为历史和地区特色的象征。对色彩无意义的使用所导致的视觉压力和低质量生活,阻碍了高质量设计的产生,降低了客户的满意度。虽然色彩有助于以相对较小的成本提高工业竞争力,但没有色彩标准就无法控制其有效性和经济性。为了最大程度地减少色彩的使用数量,色彩应以恰如其分的方式表现出来,并反映基于标准化色彩语言的决策。另外,由于与人类情感息息相关,色彩标准应该是可变并且主观的。因此,色彩标准包含了为改善环境对色彩定量和衡量的全部过程,但在体现各地区环境、个性以及特色方面,色彩标准的掌握尚存在不足之处。

摘要：In order to assess Roland Barthes＇ argument that interpretation of photography depends on cultural codes embeddedtherein, a collection of photos from the Japanese Government-General of Ch6sen （GGC）, which controlled Korea1910-1945, were examined. These colonial images and associated text, commonly in English, were aimed primarilyat the West, with which the Japanese sought alignment. Of the three common categories of GGC photos, ＂scientific＂or ＂anthropological＂ images corresponded with portrayals by Western colonial powers of the supposed inferiornature of subjugated peoples and cultures. Individuals in such pictures tend to lose their identities and are reducedto a stereotype, less human than the observer. ＂Before and after＂ photos depicted alleged GGC progress in suchareas as education and infrastructure. Pictures of ＂happy colonial subjects＂ conveyed an impression of Koreansenjoying the benevolence of the new administration. While this photojournalism favorably impressed someWesterners, others employed images of the 1919 Korean uprising, and its suppression, to discredit the *** overall assessment demonstrates the polemical manipulation of photography.

摘要：以跆拳道、太极拳和乒乓球为例,分析亚洲体育项目在北美的组织与发展状况。结果显示:通过建立消费者意识、迎合消费者健身和自我保护的需要、招募俱乐部会员和设计完备的竞赛系统,跆拳道在北美的推广较为成功;乒乓球在北美的组织与发展水平次之;太极拳在北美的组织与发展水平最低。建议:建立地区网络进行积极的市场推广,通过表演赛、青少年训练营、媒体渗透等方式,调整项目的非本地元素以适应本地环境,促进亚洲体育项目在北美的良性发展。

摘要：Rising energy costs and growing environmental awareness motivate a critical revision of the design of distillation units. Systematic design techniques, such as the rectification body, column profile map, and temperature collocation methods, require exact knowledge of all pinch points in a particular system, because these stationary points delineate the possible composition trajectories realizable in separation columns. This paper demonstrates novel methods for rigorously determining all pinch points for the constant relative volatility, ideal and non-ideal systems. Constant relative volatility and ideal solution systems are transformed into one-dimensional polynomial and nonlinear functions, regardless of the number of the components. A deflation method is proposed to locate all zeros in ideal and non-ideal zeotropic problems. For more challenging non-ideal problems, a novel hybrid sequential niche algorithm is used to solve hard azeotropic problems successfully. Finally, the design implications of these pinch point locations are investigated to show how new separation configurations can be devised. Methodically the paper points out the use of rigorous pinch point computations in conjunction with continuous composition profiles for robust distillation design.

摘要：中国电影在韩国的传播与接受经历过一个漫长的发展阶段,曾获得过韩国观众的认可好评。“同属于东亚的中、韩两国,有着相似的历史背景及文化特征,再加上中国积极与十几个国家签署合拍协议,推进电影产业国际合作交流,中国电影得以在韩国电影市场进一步传播。”[1]中韩学者就此历程进行过针对性地梳理和探讨:韩国学者朴春植在《华语电影在韩国1977-2008》一文中,按时间顺序阐述了1977-2008年中国电影在韩国市场中的发展轨迹,他研究指出的“电影版权的维护、发展独立电影和艺术电影”[2]等问题依然是今天中国电影在韩国电影市场传播与推广时需要参考的。

摘要：韩国三星美术馆Leeum是具有世界水平的韩国最大的私立美术馆之一。美术馆位于城市中心住宅区,由两栋美术馆和一栋儿童教育文化中心结合在一起,分别由三位世界著名建筑师:瑞士的Maria Botta,法国的Jean Nouvel和荷兰的Rem Koolhaas负责设计,代表了一种群集性美术馆的发展方式。
