一般位置直线段实长及倾角讲解方法的探讨

从观察日常生活中诸多部件或零件开始,引出一般位置直线实长及其对投影面倾角求解的必要性,给出由投影求出一般位置直线的实长及其对投影面倾角及直线与投影轴夹角的方法,总结实长、倾角和夹角的求解规律。而后通过几个典型习题的作图过程分析,加深学生对定理的理解。几轮讲述表明：采用该种形式学生不仅能够快速掌握直角三角形法,而且也能激发学生学习工程制图的兴趣。

金融控股集团风险传染的一般均衡:基于内部关联交易的模型分析

金融控股集团因其内部关联交易产生规模经济、范围经济和X效率优势,但金融控股集团的关联交易,特别是以内部借贷为主的资金关联交易,在充分发挥集团化协同优势的同时,也产生了风险传染问题.本文在传统的传染均衡研究基础上,引入了金融控股集团中“关联交易”这一重要因子,构建了一个基于内部关联交易的传染均衡模型,使模型更逼近于金融控股集团传染的真实特征,深入研究了金融控股集团内部传染的主要特征与效应.     

Medicine and literature: a section in a medical university library

Objectives: In 2007, the Alberto Malliani Medical Library of the Università degli Studi in Milan decided to order some novels for its students. The library purchased 24 titles written by famous authors and planned to add others in the future. The proposal for this action was made by a professor, with whom the library had previously co‐operated in organising meetings for students. This article summarises the results of this experiment over 4 years, from its conception, to determine whether any positive outcome has resulted, including how library users welcomed this addition to the library and evaluation of its economic sustainability. Results: Data from July 2007 to December 2010 are presented in terms of the initial purchases, costs, and volume of lending for this section of the library; in addition, readers’ preferences are examined. Conclusions: A university medical library can act as a stimulus to its students’ new or renewed interest in literature, assuming that the novels, biographies, and short stories can contribute positively to the training of medical students. Therefore, setting up a special section can be useful, even though the costs of this section must be limited. A questionnaire could be the method of gathering information about users’ assessment.

Vapor-liquid equilibrium simulation of binary and ternary mixtures of CH4, C2H4 and iso-C4H10

The vapor-liquid equilibrium（VLE） properties for the binary and ternary mixtures of CH4,C2H4 and isoC4H10 are of great importance in the recovery of ethylene from mixture containing CH4 and C2H4 with iso-C4H10 as solvent.Hence,Gibbs ensemble Monte Carlo（GEMC） simulations were used to estimate vapor-liquid equilibrium for the binary and ternary mixtures of CH4,C2H4 and iso-C4H10 with the united atom potential NERD model.The selected simulation conditions are based on the experiment in the literature.The results of this work were shown to be in satisfactory agreement with available experimental data and predictions of Peng-Robinson equation of state.The structure of simulated liquid phase is also characterized by radial distribution function（RDF）,which contributes to further understanding of the VLE curve of these systems.RDF is not sensitive to the pressure and temperature range.With the increase of pressure or the decrease of temperature,the molecules tend to gather together.     

马克思主义群众路线教育方法的新境界——学习习近平总书记用统筹兼顾方法搞好群众路线教育实践活动

"统筹兼顾"思想体现了马克思主义哲学关于事物之间相互联系和关照全局与局部的观点,"统筹兼顾"是党委(党组)开展群众路线教育活动的基本方法,既要解决群众反映强烈的突出问题又要做好当前工作,对于"四风"问题既要着力治标又要注重治本。要运用统筹兼顾方法提高党员干部服务群众的能力和水平,既要在改进作风上抓住主要矛盾和矛盾的主要方面,又要在慎独慎初慎微上狠下功夫;在为民出实策鼓实劲办实事、取得工作新进展上下功夫。改革发展稳定是我国经济社会发展进程中三个带有全局性、综合性的重大问题,要促进群众路线教育实践活动与提高改革决策科学性相统一,促进群众路线教育实践活动与全面推进发展相统一,促进群众路线教育实践活动与维护社会稳定相统一。     

从十万卷楼抄本《章学诚全集·士习》看《文史通义·感遇》的文本写定

嘉业堂刻《章氏遗书》本《文史通义》标注有目无文的《士习》一篇,其实并未逸失。《士习》篇最早由周作人从十万卷楼抄本《实斋全集》中发现,并刊布在《国立华北编译馆馆刊》1943年第2卷第5期的开卷第一篇。由于时值日本侵华,且《馆刊》流通不广,这一发现并未引起学界的注意。十万卷楼抄本《实斋全集》今藏国家图书馆,经查阅,《士习》篇确实保存在第5册之中。《士习》并非如周作人跋语所说是《文史通义》内篇《知难》的初稿,而是《感遇》篇的初稿。通过《感遇》与《士习》16则歧异文句的文本比勘,可微观考察章学诚对著述删润写定的不同形式,并进而体察章氏学术思想与行止心境的变迁。     

《翁方纲纂四库提要稿》长编价值例说——以经部为中心

《翁方纲纂四库提要稿》是翁方纲所写的《四库全书总目》初稿,对于《四库全书总目》研究具有重要的史料价值。《翁方纲纂四库提要稿》中很大部分是翁方纲所辑录的资料长编,前人未注意到其长编的价值。事实上,长编所载之书名、作者、卷数、序跋、印鉴、版本信息、翁方纲校语等信息对《四库全书总目》研究具有重要的价值,可借以考证作者生平、底本信息、书名流变、书籍流传、内容删改及《四库全书》馆臣之校理意见。
