新型吸附式冷管的最低制冷温度影响因素研究

提出了一种新型的余热固体吸附式制冷管．该种制冷管无节流装置、无运动部件、结构简单、强度较高，且每根管子自成一个完整独立的制冷系统，所以其密封性好、使用方便；研究了在吸附剂量不变的情况下，制冷剂(吸附质)充注量对制冷管性能的影响。由于该种制冷管的性能跟外部环境参数具有较强的耦合性，本文就热源温度、环境温度、风速和环境空气湿度等参数对其最低制冷温度的影响进行了实验研究，实验采用的工质对为13X沸石分子筛-水．     

《三国演义》中诸葛亮“羽扇纶巾”形象及其人格内涵

诸葛亮是《三国演义》的作者罗贯中倾注全部热情和笔力塑造的艺术典型。诸葛亮的“羽扇纶巾”形象有一个较漫长的形成过程,其大致经历了三个阶段：魏晋野史传说中的名士形象、宋代词作中的儒将形象、元明杂剧中的道教军师形象。诸葛亮“羽扇纶巾”的外部形象流泻出疏淡闲雅、潇洒飘逸、从容不迫的精神风范,表现出道家“自然”人格的特征。同时,诸葛亮又具有“儒者气象”,体现了“以道持守”的儒家道德人格,两者相济互补、相辅相成。     

位移边界对2D-FGM板热应力影响研究

考虑不同的位移边界条件,建立了常物性2D-FGM板研究模型,并采用有限元法,得到其冷却瞬态热应力场分布图形。位移边界条件对常物性2D-FGM平面区域冷却瞬态热应力分布影响颇大,在简支和一端固定情况下,2D-FGM板自由边界上的热应力σ_x=0;两端固定情况下,其左右两边界均形成上中下三个应力聚集,应力分布形状和数值都发生了巨大的变化;将四周均设置呈固定约束后,热应力数值增长幅度较两端固定情况时更为明显。此结果为该材料的设计、制备提供了准确的理论计算依据。     

《广雅疏证》以"凡"语说明"名"、"实"、"义"关系情况浅析

《广雅疏证》以"凡"语说明"名"、"实"、"义"之间的关系。其中包括两种情况:一、以"凡"语说明某些"实"之得"名"缘由和某些"名"所指的"实"的内容范围,指明"名"与"实"之间的关系。二、以"凡"语说明相同、相近、相因之"义"分别用相同之"名"或音同音近之"名"表示,指明"名"与"义"之间的关系。     

略论《桃花扇》中对儒家士大夫的批判

作为孔子的后代,深谙儒家之道的孔尚任在他的名著《桃花扇》中,对作为儒家代表的士大夫阶层,虽然也隐微地寄予了自己救国救民的期望,但更多的则是对他们或祸国殃民,或无能救国的批判,而赞扬了被孔子认为“难养”的“女子与小人”的侠肝义胆,有勇有谋,并在他们身上寄托了未来的希望。这不能不说是对儒家政治观的一大发展。     

Authenticity as a form of worth

Scholarly engagement with authenticity has been revitalized by recent efforts to theorize the value-ladenness of authenticity claims. Yet, these approaches are restricted by the lack of available conceptual tools necessary to explain variations in the meaning of authenticity between different cultural forms and social groups. In this paper, I draw from Boltanski and Thevenot’s pragmatic hermeneutics to develop an approach to authenticity in popular culture that conceptualizes it as a form of worth. I apply this new model to an analysis of the meanings of authenticity found in the discourse of fans of indie music and country music. I find that in the indie genre, authenticity involves an inspirational form of worth; in the country genre, it involves a domestic form of worth. I trace these differences back to the matched relationship between the primary groups of fans of each genre and the genres themselves that led both sides to find an interest in these types of authenticity. I conclude by sketching the relevance of this approach for explaining overarching concerns for authenticity in late modern societies.     

冷却剂参数对铣槽喷管低周疲劳寿命的影响

采用有限体积流固耦合计算方法、非线性有限元热结构耦合分析方法和局部应变法研究大面积比铣槽喷管三维再生冷却槽道在循环工作条件下的热结构变形与低周疲劳寿命,并对比分析了冷却剂质量流量与入口温度对铣槽喷管疲劳使用寿命的影响。计算结果表明,铣槽喷管热结构响应呈现复杂的三维效应,应变较大位置主要分布在与肋连接的内衬区域,喷管中部的残余应变量最大;冷却槽道低周疲劳寿命分布和热结构响应基本一致,最小寿命位于喷管中部与肋相连的内衬区域燃气侧;随冷却剂质量流量增加,铣槽喷管低周疲劳寿命不断提高;随冷却剂入口温度增加喷管尾部低周疲劳寿命值不断降低,而喷管中前部的低周疲劳寿命值却不断提高,当冷却剂入口温度为280K左右时,本文的铣槽喷管总体使用寿命达到最大。      

Everyday Life,Everyday Death

In this article I note limits of cultural activism in third-wave feminism, demonstrating that this activism often relies on a music scene that neglects intersections of race and gender. I offer the space of the online fansite as an alternative site for analysis, describing it as a site for everyday activism and consumer activism. Specifically, I explore the online fansite of the HBO show Six Feet Under, describing how fans treat subjects of gender and race in the show and in their everyday lives. Although fans discuss race and gender in limited ways in their explorations of the show and their daily lives, when they discuss the subject of death, they more productively address intersections of both race and gender, considering differences in burial and funereal practices among diverse cultures. Fans also construct the fansite as a place for consumer activism, sharing information about how to be active consumers in the funeral industry and to direct the course of their own burials.
