简论《周易》对《汉书·艺文志》的影响

班固的《汉书·艺文志》源于刘向及其子刘歆的《七略》,是我国现存最早的目录学文献。《汉书·艺文志》中多处引用《周易》,并尊《周易》为“五经之原”,充分体现了汉初《周易》在学术界及思想界的重要地位,从中还可看出《周易》在汉初已成为儒家立论言说的理论基础及辨章学术,考镜源流的“万方之略”。

从《器象显真》看西方工程图学的引进

《器象显真》是我国第1部引进西方机械制图的译著，曾对中国工程图学走向近代起到十分重要的作用。笔者以此为题简述了徐寿父子的图学实践，讨论了徐建寅所译《器象显真》的主要内容，以及对西方工程制图著作进行翻译所取得的成就。     

林纾“白话道情”考论

自林纾“五四”前夕声称庚子年曾为《杭州白话报》写作“白话道情”，迄今无人查证，致使其本来面目长期以来不为人知。1901年《杭州白话报》刊发的署名“竹实饲凤生”的六种“道情”，应是林纾之作。襄助《杭州白话报》，创作“白话道情”，以白话开民智，以通俗文艺振民气，且曾产生了广泛的社会影响，是20世纪初年的壮年林纾确曾有过的一段白话文学创作经历。《杭州白话报》“白话道情”之考论，还原了林纾作为晚清开风气之先的启蒙白话报和白话文学先驱者的本来面目。     

双面全异绣工艺技术与艺术特质的融合

双面全异绣是湘绣工艺技术与艺术特质达到巅峰的标志,但有关其工艺技术与艺术特质结合的研究较少。为此,以双面全异绣的诸多现存作品为例,从绣稿工艺设计、内容题材表现、画面构图的时空转换、刺绣针法对艺术特质的表现能力等方面进行分析,探讨双面全异绣高超工艺技术与优良艺术品质完美结合的方式。在此基础上指出保持湘绣的独特艺术特质和刺绣工艺技术是湘绣在现代社会传承和发展的必然选择。     

Preference for newspaper size

The past few years has seen a change in the size of newspapers, with publishers moving to a smaller size format. Five ‘standard’ newspaper sizes are used in different countries: Broadsheet, Rhensch, Tabloid, Tall Tabloid and Berliner. These papers vary in both width and height of pages and hence there are implications for human reading comfort, which may be dependent on reading location such as on a lounge chair or on a train. Experiments were carried out to determine preferences for the different sizes and to relate these preferences to the geometric characteristics of the newspapers. For both comfortable and cramped/uncomfortable reading conditions, the rank order of preference for paper types was, from least to most-preferred, Broadsheet, Rhensch, Berliner, Tall Tabloid and Tabloid. Preferences were much stronger when determined in cramped/uncomfortable reading conditions, where most comparisons were significantly different. There was good correlation between participant ratings on several scales and preference, where most factors were related to comfort of holding and controlling the paper.     

Thermal inertia of newspaper sandwiched aerated lightweight concrete wall panels: Experimental study

A short term experimental investigation on the thermal inertia: time lag and decrement factor of aerated lightweight concrete (ALC) wall panels is the main purpose of this study. ALC wall panels of different density and different aerial intensity of newspaper sandwiched were produced and erected on a prototype house. All wall panels were installed facing east direction and subjected to natural environment or tested under transient condition. The inner and outer surface temperatures of the wall panels were recorded at 3 min interval, 24 h a day. Time lag and decrement factor were computed from the surface temperatures recorded. The results showed that newspaper sandwiched ALC panel has greater time lag and lower decrement factor compared to ordinary ALC panel. It is found that time lag and decrement factor were influenced by the thermal diffusivity value of the wall panel. The thermal inertia property of the panels was negatively related to its thermal diffusivity.
