烧结机烧结冷却阻力的计算

为合理设计钢铁企业冷却烧结机的风压,对风压基本参数——烧结机烧结冷却阻力进行了理论推导,建立了阻力计算的数学模型,并基于C＋＋Builder开发了相应于模型的计算程序.通过实例对程序和算法进行了验证.结果表明,计算结果与实际相符,说明模型正确.该计算程序简单明了,可广泛应用于冶金行业进行烧结机烧结冷却阻力的计算.     

Fan activism sustained and challenged: participatory culture in Chinese online translation communities

Henry Jenkins, in Convergence Culture, argues that “[p]opular culture may be preparing the way for a more meaningful public culture”. This article examines this argument in the context of online translation communities in China, which originated from fan groups interested in foreign comics, games, movies, and television dramas. Drawing on evidence collected through participant observation and 23 in-depth interviews, this article first reviews the historical development and the structural layout of such online translation communities. It then focuses on the motivations of their members to contribute to the translation tasks, which show that personal interests speak louder than collective goals. Finally, it analyzes how the collaboration structure, mindset of collaboration, skills, and sense of agency are transferred from translating entertainment content to civic education content (i.e. open courses). Participatory culture fostered through fan activities is found to be transferred into civic engagement; however, the transfer between fan activism and political participation is yet to be seen.

一桩宋词公案的反思－－小晏词名句考辨

文学史上，对于晏几道的“舞低杨柳楼头月，歌尽桃花扇底风”中的“风”，历来解释分歧：有自然界的风、扇子扇出来的风、歌唱的快速节拍、回荡的声音波、桃花扇子下的风、月落时息止的风。本文考辨，是应为桃花季节的风，并将此二句置于古典文学歌舞描写流变史中，考察其审美价值。

“Xenasubtexttalk”

This article examines how some lesbian fans of the television adventure fantasy series Xena: Warrior Princess (X:WP) (1995–2001) became visible through the development of online fandom and the production of explicit lesbian Internet fan fiction. The self-identity of lesbian fans who are part of the “xenasubtextalk” (XSTT) fan group is explored and celebrated through social networks of lesbian fandom through the “Xenaverse.” Lesbian fans have written copious amounts of fan fiction online enabling a form of lesbian political discourse and activism as well as social and cultural discourses shared throughout the platform of the Internet. Many lesbian fans have been supported to create and write Xena lesbian fan fiction by engaging with various lesbian fan writers from the Xenaverse who offer their advice to develop lesbian fan fiction services for free to “newbie” writers. Their explicit lesbian fan fiction narratives are reproduced and distributed as lesbian stories about the two main characters Xena and Gabrielle from the original television series. I interviewed three women from “xenasubtextalk” who gain pleasure exploring their lesbian identities and fandom through the fan group.     

折扇中的日本文化

时至今日,折扇如同樱花、富士山一样,已成为日本的象征。小小的一把折扇,对日本人来说却蕴藏着丰富多彩的内涵,彰显着绚烂多彩而又有日本特质的扇文化。日本折扇在创制之始曾一度是身份和地位的象征,之后日本人用它驱暑纳凉、招神辟邪、馈赠友人、礼仪社交。折扇还是舞台表演的传神道具,其扇面艺术和扇骨雕刻尽显其艺术价值。折扇文化是日本传统文化中熠熠生辉的瑰宝。     

加箍约束压缩机和吸声导流锥的气动声学研究

设计了两种新型的降噪技术装置-加箍约束式制冷压缩机和针对风机噪声的吸声导流锥结构，加箍约束式制冷压缩机不仅使压缩机具有优越的低频抗噪能力，还解决了其他传统方法无法避免的压缩机散热问题，吸场所地流锥是利用泡沫塑料作吸声体，降低二次噪声，并有导流作用，与传统方法相比，其优点是结构简单，成本低、降噪效果好。
