上海时装周终于尘埃落定,一年两次,十余天不长的时间里,我们在新天地秀场这片舞台,看尽各色奇葩街拍与精彩T台。常规的T台摄影为官方发布而生,普通的时尚街拍转瞬就变成有心人士"捉妖记"的素材。我们的时装周摄影,还缺少一些什么?一位叫Jason的非专业摄影师,在众多拍摄时装周的摄影师中,他的心一直先于眼,记录着时尚在特定瞬间的张力。每一年,他眼中的上海时装周,总会有些特别。 相似文献

<正>喜欢上海,是因为她如同春天那样新鲜跃动、生气勃勃:更喜欢上海,是因为这所城市依稀弥漫着上世纪30、40年代的奢华与时髦。都说"老上海"已不在上海了,精致的街道、古朴的唱片、优雅的旗袍,仿佛在王家卫与关景鹏的影视作品中唯有再现……殊不知,在上海的松江,仍保留着一方能够尽情享受老上海风情的寸土——上海影视乐园。上海影视乐园由上海电影集团投资建设,是集影视拍摄、旅游观光和文化传播为一体的主题乐园。园区占地43公顷,由"三十年代南京路"、"欧式庭院"、"石库门里弄"、"教堂"、"浙江路钢桥"、 相似文献

Beginning in 1990, the major automotive passenger vehicle manufacturers once again re-evaluated the potential of the battery powered electric vehicle (EV). This intensive effort to reduce the battery EV to commercial practice focused attention on the key issue of limited vehicle range, resulting from the low energy density and high mass characteristics of batteries, in comparison to the high energy density of liquid hydrocarbon (HC) fuels. Consequently, by 1995, vehicle manufacturers turned their attention to hybrid electric vehicles (HEV). This redirection of EV effort was highlighted finally in 1997, at the 57th Frankfurt Motor Show, the Audi Duo parallel type hybrid was released for the domestic market as a 1998 model vehicle. Also at the 1997 32nd Tokyo Motor Show, Toyota Hybrid System (THS) Prius was released for the domestic market as a production 1998 model vehicle. This paper presents a comparative analysis of the key features of these two 1998 model year production hybrid systems. Among the conclusions, two issues are evident: one, the major manufacturers have turned to the hybrid concept in their search for solutions to the key EV issues of limited range; and, heating/air conditioning; and two, the focus is now on introducing hybrid EV for test marketing domestically 相似文献

如果把四年一届的夏季奥运会比作一本书,那么开幕式无疑就是这本书的卷首语,有着举足轻重的地位。伦敦奥运会开幕式的神秘面纱已经被揭开,和4年前的北京奥运会一样,伦敦也将英国的本土文化深深融入进了开幕式中。虽然开幕式秉承的是节俭,但这出小成本的开幕式却演绎出了经典的大味道,让我们从表演、点火、以及旗手这三个视点角度来解读这场盛宴遗留下的财富。 相似文献

In the year 2000, the automotive manufacturers turned their attention to Hybrid Electric Vehicles (HEV). This re-direction of Electric Vehicle (EV) development effort was highlighted at the North American International Auto Show (NAIAS 2000), where, the World's major automobile manufacturers displayed twenty three HEVs. Thirteen HEV were configured with an internal combustion piston engine and electric traction motor, while, ten additional HEV were configured as fuel cell and battery pack hybrid vehicles (FCHV). Furthermore, the FCHV were fueled with hydrogen (H2) from H2 absorption metal hydride fuel tanks, or, from liquified hydrogen cryogenic fuel tanks. One conclusion for HEV was that the preferred configuration includes a compression ignition engine paired with an electric motor, and, four speed manual transmission with automatic shift. A second conclusion for FCHV was that the fuel of choice is H2, and furthermore, these H2 fueled FCHV were the precursor vehicles foreshadowing deployment of a hydrogen fuel infrastructure within the first quarter of the 21st Century 相似文献

To diagnose the Open-Circuit (OC) fault in the novel fault-tolerant electric drive system, based on d-q-axis current signal, a strong robustness diagnosis strategy is proposed and investigated. Fewer independent power supplies and converters are required in the novel fault-tolerant electric drive system based on Dual-Winding Permanent Magnet Motor (DWPMM), and the system’s reliability, usage ratio and power density have been improved compared to the conventional fault-tolerant motor drive system. However, the novel fault-tolerant electric drive system has the OC fault diagnostic false alarms issue when load changes suddenly or under light-load condition. And it lacks the research on the diagnostic method when the system encounters intermittent OC fault in power switches. By theory derivation, simulation and experimental verification, it can be concluded that the proposed strong robustness OC fault diagnosis strategy based on d-q-axis current signal can overcome the OC fault diagnostic false alarms issue when load changes suddenly or under light-load condition. And it can detect and locate the OC fault of single-phase winding in real time, and diagnose the intermittent OC fault of power switches. 相似文献
