陈元通宝背七小记

陈元通宝背七,小平,对读。为近年新发现品种,出自越南。目前仅知两品(图1)。十多年前粤人苏瑞光氏于广西所得,后归可居先生宝藏,是泉生坑绿锈,精整完好(图2)。予今年春手拓,实物为传世品。查拓本两品分属两版,然笔意、制作大同小异。是泉阔缘薄肉,文字制作类安南陈朝(1225-1257)初期铸币,尤其“通”字与陈太宗建中通宝、政平通宝之文字宛如一人所书。安南陈朝开国于南宋理宗宝庆元年(1225),亡于明惠帝建文元年(1399)。陈太宗皇帝八岁建国,国号安南,年号建中,建中七年改元天应政平,十九年改元元丰,元丰七年崩。圣宗即位后,改元绍隆,此后因蒙…     

Mössbauer Spectroscopic and Chromaticity Analysis on the Colourative Mechanism of Ancient Goryeo Celadon from GangJin and Buan

In ancient Goryeo celadon excavated from the kiln sites in the GangJin and Buan areas, the effect of the chemical composition and ionic state of Fe on the colour was evaluated by Mössbauer spectroscopy and chromaticity analysis. According to chromaticity analysis, the L* value (brightness) of the glaze was shown to be affected more by TiO₂ and MnO than by Fe₂O₃, and the body was affected more by Fe₂O₃ than by TiO₂. The a* value was found to be affected by Fe₂O₃ and TiO₂ in the glaze, whereas there was hardly any change in the body according to the composition. As for the b* value, changes due to the composition were shown to be smaller than those for the L* and a* values. According to the Mössbauer spectroscopy results, as the quantities of TiO₂ and Fe₂O₃ are increased, Fe²⁺/Fe³⁺ decreases; while the changes in Fe²⁺/Fe³⁺ with MnO and P₂O₅ are negligible. As the quantity of Fe²⁺/Fe³⁺ increases, the a* and b* values decrease, which results in the change of colour from red–yellow to blue–green. The characteristic green colour can be attributed to increased L* (brightness) and decreased a* and b* values (blue–green shift) due to the reduced Fe ion, which is mainly determined by the TiO₂ and Fe₂O₃ contents.

Predicting Ductile Crack Initiation of Steel Bridge Structures Due to Extremely Low-Cycle Fatigue Using Local and Non-Local Models

The strain-based prediction model combining the Miner's rule and Manson-Coffin's relationship provides a local parameter for evaluating the ductile crack initiation of steel structures, and some modified models based on it were proposed to evaluate extremely low-cycle fatigue (ELCF) behaviors of steel structures. Previous research has confirmed these local models to be an accurate index for ductile crack initiation in steel bridge piers, however it is found to quite depend on the mesh size of the numerical model used. In this study, a non local damage parameter is presented and successfully applied to ductile crack initiation life assessment of steel bridge piers subjected to earthquake-type cyclic loading. The non local damage parameter is based on averaging the strains over the effective plane using a weight function in the exponential form, and introduces the non local damage parameter to replace the local state variable. Finite element analysis with three different mesh sizes is employed. Comparisons of the local and non local solutions with those of experiments indicate that the non local prediction model can predict the ductile crack initiation of steel bridge piers with good accuracy regardless of the specimen geometries and loading histories, meanwhile the mesh independent nature of the non local model is also demonstrated.     

河南博物院藏《唐人写经》卷的纸张研究

河南博物院藏《唐人写经》卷,纸张确认为麻纤维。纸张厚度不均匀,属于较厚的麻纸。水平帘纹很宽,因此判断所用模子不规整。纸张渗透性好,说明纸张原始施胶技术上乘。纸张尺寸符合唐代宗教手稿用纸习惯,基本符合8世纪的宗教手稿情况。     

民营超市购物选择行为影响因素的模型构建与实证研究——以福州市为例

解放战争时期香港《华商报》的历史地位和特点

1946年复刊后的香港《华商报》是中共在香港创办的一份有重大影响的报纸,它不仅是宣传中共的坚强舆论阵地,也是联络统战工作的联络站。它内容丰富,涉及到政治、军事、外交、经济、文化等多方面,全面反映了解放战争时期国内外生动的历史画卷。它以其独特的方式积极探索了在资本主义条件下办社会主义报纸的特点,为今天媒体的换位思考可提供某些经验。     

金代教材建设

作为金代教育重要内容的教材建设,以往学界研究甚少,成果聊聊无几.事实上,金代教材建设承袭唐宋,虽无唐、宋发达,但也比较完善.既有传统的经史教材,也有文学教材、专科教材、儿童教材;既有汉文教材,也有女真文和契丹文教材.类型多样、特色鲜明的教材体系成为金代教育的重要组成部分,对金代教育的发展起到积极的促进作用.本文试就金统治者完善教材体系所采取的措施、教材划分标准、教材种类、教材特点及与科举考试之间的关系等问题进行初步研究.
