明代《应天府志》有万历五年（1577年）刻本、万历二十年（1592年）刻本、正德十四年（1519年）本和《永乐大典》本。《永乐大典》本《应天府志》中的佚文具有十分珍贵的文献学价值和史料价值。 相似文献

语文教学效率包括知识的数量、能力的训练、思想教育的效果等。决定教学效率的因素是多方面的,如学生因素、教材因素、教法因素等,但教师因素是影响教学效率的主要因素,因为教师在教学中起主导作用。在中学各门学科中,语文课的综合性最强,内容覆盖面广,所以语文教师应成为一个“杂”家。 相似文献

初冬的早晨,我习惯性地走在北京地铁熟悉的通道里。身边人擦肩接踵的是这 个时刻固有的熙来攘往的人群,匆忙的,目标明确却少有表情。 对面站台硕大明亮的灯箱广告时时被驶过的列车挡住又让开,那幅匈牙利布达 佩斯的广告已经挂出来很久了:链子桥、多瑙河以及两岸缓缓游动的车河,平 板而过于标致性,却每每都使我再度想起这个曾经匆匆走过的国家,《布达佩 斯之恋》中的那首《忧郁的星期天》,那些故事、场景和细节也会紧跟着回到 感觉里,影片中无论是开始时的清晨还是结束时的夜晚,那长镜头也是如此标 致性地透过链子桥慢慢地一路摇过宽阔的多瑙河,传递着这个国家忧郁而浪漫 的气质。 相似文献

Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags. 相似文献

The bodies and glazes of 27 early Western Zhou proto‐porcelain samples from Yejiashan cemetery, Hubei Province, were analysed using LA‐ICP–AES, SEM, XRD, a thermal expansion instrument and other analytical methods. The results indicated that the bodies of all samples were characterized by high silicon and low aluminium, and were made with porcelain stone raw materials found in the south of China. The glazes are typical of high‐temperature calcium glazes of the CaO (MgO) – K2O (Na2O) – Al2O3 – SiO2 series, with relatively high Mn and P content, which was probably caused by the addition of plant ashes. The physical properties and phase compositions of Yejiashan proto‐porcelain show that firing processes were still in the early stages of development in ancient China. Multivariate statistical analyses indicated that Yejiashan proto‐porcelain might have come from the Deqing area, in Zhejiang Province. These results provide new archaeological evidence for research on issues related to material flow in the Western Zhou dynasty. 相似文献

Geographical distance constitutes friction in searching for research collaborators. Taking advantage of a quasinatural experiment featured by High-Speed Railway (HSR) lines in China, this paper employs the difference-in-differences model to identify the causal impact of a substantial improvement in the intercity transportation infrastructure on collaborative innovation across cities. The data pertain to a universe of patent applications filed by Chinese universities and their citations. We find that HSR contributes to a substantial increase in the innovation quantity and quality of collaborative patenting innovation between universities and corporates. It contributes to industry collaboration by utilizing university academic disciplines in the related technology fields. Lastly, HSR facilitates universities to search for new research partners with better quality beyond the geographical boundary. 相似文献
