从《春秋》三书看元儒程端学的义利观

元儒程端学在阐发《春秋》“大义”的同时,申明了自己重义轻利的义利观.这是一种进步的义利观,对我们今天的道德建设,亦具有一定的借鉴和指导意义.     

承载传统文化见证战争历史--北京市丰台区档案馆卢沟桥珍贵史料展示

丰台区位于北京西南,在商、周时期为蓟和燕国之地,源于"丰宜门外拜郊台"而得名.悠久的历史在丰台这片古老的土地上留下了深深的印迹,具有八百多年历史的卢沟桥是体现丰台深厚的历史文化底蕴的见证之一,一直以其精湛的造桥技术和精美的桥梁建筑艺术而闻名于世,曾被十三世纪意大利人马可波罗称为"世界上独一无二的桥".而震惊中外的"卢沟桥事变"因打响了中国人民全面抗击日本帝国主义侵略的第一枪,而载入光辉史册.     

中国为什么不能搞西方那样的多党制

近年来鼓吹中国必须搞西方多党制的思潮越来越公开化,对于这种错误思潮,我们绝不能掉以轻心.实行多党竞争、轮流执政制度要有一定的历史条件,就是要以实行一个制度、一种政治纲领、一本宪法为前提条件.中国历史上对西方多党制的尝试及失败表明:只有在中国共产党的领导下,以马克思主义为指导,坚持社会主义制度,才能实现社会主义现代化和中华民族的伟大复兴.坚持和改善共产党的领导,关键是健全对执政权力的监督制度.     

和谐 真实 合式——贺拉斯《诗艺》的美学思想新探

古罗马诗人兼文艺理论家贺拉斯的《诗艺》虽然创见不多,但也蕴涵着丰富的美学思想。和谐、真实、合式是其中最主要的最有价值的美学思想。当然,和谐、真实、合式在贺拉斯的美学思想中是统一的,和谐是核心,真实和合式是达到和谐的途径。从整体上看,贺拉斯的美学思想仍然体现着西方古代的“和谐”这一传统的美学观。     

Preparation and characterization of TiO2/expanded graphite

In order to obtain anatase TiO2/expanded graphite with high expansion volume, titania gel was introduced to expandable graphite surface by sol-gel process, and then the composite was expanded and calcined at high temperature. The samples were analysed by using scanning electron microscope (SEM), X-ray diffraction(XRD), energy disperse spectroscopy(EDS), and differential scanning calorimetry(DSC). The optimal conditions for preparation are as follows: the molar ratio of tetrabutyl orthotitanate to triethanolamine is 1∶0.4, and the calcination and expansion temperature is in the range of 650-750 °C. Under such conditions, the expansion volume of composites could reach 98 mL/g, and the mass loss ratio is less than 5%. The analysis shows that lower temperature and smaller particle size of graphite are helpful to the formation of anatase-type of TiO2, but larger particle size will lead to lower mass loss ratio, and higher temperature and larger particle size will lead to higher expansion volume.     

Resistance characteristics of innovative eco-fitness equipment: a water buoyancy muscular machine

This paper propose innovative eco-fitness equipment—a water buoyancy muscular machine (WBM machine) in which resistance is generated by buoyancy and fluid resistance. The resistance characteristics during resistance adjustment and under isometric, concentric, eccentric and isokinetic conditions were investigated and compared to a conventional machine with metal weight plates. The results indicated that the isometric, concentric and eccentric resistances could be adjusted by varying the water volume; the maximum resistances under isometric, concentric and eccentric conditions were 163.8, 338.5 and 140.9 N, respectively. The isometric resistances at different positions remained constant in both machines; however the isometric resistance was lower for WBM machine when at a position corresponding to a 5% total displacement. The WBM machine has lower resistance under eccentric conditions and higher resistance under concentric conditions. Although the conventional machine has an identical trend, the variation was minor (within 4 N). In the WBM machine, the eccentric resistance was approximately 30–45% of the concentric resistance. Concentric resistances increased with an increase in velocity in both machines; however, the eccentric resistances decreased with an increase in velocity. In summary, the WBM machine, a piece of innovative eco-fitness equipment, has unique resistance characteristics and expansibility.
