论清初汉官的“南方情结”

明清易代之际,相当部分的汉官选择了与清廷合作。但这种政治上的认同并不等于文化上的认同,一部分汉官在入清初期表现出了对清廷很深的文化隔膜,这种心态使他们在诗歌作品中表现出浓郁的南方情结。这种南方情结既源于个人心理上的自然情绪,也是他们政治心态的微妙折射,反映了儒家传统思想对传统文人在不同历史时期的巨大影响。

武当山琉璃官窑传统手工业设备与工具的现代启示

琉璃瓦的烧制最早出现于北魏时期,其烧制技艺在明清时期达到顶峰。明代在武当山有大规模营建活动,武当山琉璃官窑烧制的琉璃构件主要是供应于此。对于传统的手工艺人而言,工具直接影响其制作质量、效率,在制作琉璃瓦的过程中,对工具的纯熟掌握直接影响作品本身的水准。这些看似简陋的传统手工业制琉璃瓦工具,包含了一脉相承的设计思想,文章将分析琉璃瓦制作工具中蕴含的传统造物思想,为现代产品设计提供更好的范本。

Interfacial reaction between the oxidized SiC particles and Al-Mg alloys

The interfacial reactions of oxidized SiC particles reinforced Al-Mg matrix composites were investigated by the field emission-scanning electron microscopy (FE-SEM), TEM and X-ray diffraction. It was found that the nanoscale MgO forms initially due to the interfacial reaction, then whether it reacts with molten Al continuously or not depends on the content of Mg in the matrix and its covering densification at the surface of particles. When there is not enough Mg in the matrix for the formation of dense MgO layer, MgO will transform into MgAl2O4 crystal owing to the continuous reaction with SiO2 and molten Al. When dense MgO layer forms at the surface of the particles due to the affluence of Mg for the initial reaction, it will protect the inner SiC from the attack of molten Al. However, the reaction products of both MgO and MgAl2O4 are thermo-stable phases at the surface of the particles under high temperature. The results clarify the interfacial reaction route and they are of great value to the
