任鸿隽科学救国思想初探

富国强民的强烈愿望,使任鸿隽由一个革命救国的追随者,转变为科学救国的服膺者.他的科学救国思想,是对近代科学救国思潮的继承和超越.他认为,近代科学之有无是造成中西国势强弱之判的重要原因,但需指出的是,在当时的科学家群体中,像任鸿隽那样坚持强调纯科学研究者,并不多见.他大力倡导实际的科学研究,竭力促进科学的本土化,建言政府将科学立为国策,并在新中国成立后,赞成由国家统筹领导科学事业.在不同的历史阶段,任鸿隽科学救国思想的表现形式虽然各不相同,但其宗旨却是一以贯之的.     

Parametrization of the solvent action on modern artists' paint systems

A solvent action parametrization scheme has been developed combining relevant parameters of the solvent action on modern artists' paints to characterize the solvation and dissolving properties of different binding media. The new system combines different concepts used in solvent chemistry. It is based on the normalized and solute-dependent dimension [hδ_H + eE_T(30)cv]^N. It comprises a polarity value E_T(30)cv as the magnitude of the enthalpy, and a combined value representing the cavitation energy δ_H as an entropy-influencing factor. Forty-eight solvents were divided into five subgroups based on their interaction and structural properties. This binary scheme permits to reliably quantify spaces of efficiency. The graphical selectivity of the scheme was applied to four binding media systems (oil, alkyd, acrylic-, and acrylic-polystyrene) by determination of the swelling capacity of 48 solvents. The graphical visualization of the systematic parametrization of solvents permits one to judge the intermolecular interaction and other effects of solvation relevant to the restoration of painted artwork.     

现代性话语中的时尚的审美救赎简

现代性在其发展的过程中,先后断裂为启蒙现代性和审美现代性,而后者是对前者在美学上的反思和超越.作为美学范畴之一,审美现代性的建立自然离不开审美距离这一理论.德国社会学家和美学家的西美尔正是在审美距离的基础上,从生活距离和艺术距离两个维度丰富了前人的“距离说”,并将其运用到时尚理论,他详细深入地分析了时尚如何同过拉开与现实生活的距离而实现对日常生活的审美救赎的.这对我们今天的时尚发展意义重大.     

试述民国时期启蒙与救亡背景下的编辑出版活动

民国时期是中国社会的大变革时代,反映在思想文化上,则是启蒙与救亡两大主题。书刊杂志作为重要的传播手段,在这一变革中发挥了重要的作用。民国时期,西方大量的思想学说被介绍到中国来,科学与民主开始深入人心,封建主义遭到无情批判,显示了知识分子寻求救国救民之道的不懈追求。中日战争爆发后,中华民族空前团结,表现了强大的生命力和战斗力,宣传抗日救亡的书刊杂志大量涌现,救亡取代启蒙成为时代主题。
