七.千峰翠色浙江是青瓷的故乡,也是古代青瓷的生产中心,出现了越窑、龙泉窑、南宋官窑、婺州窑等著名窑口,越窑、龙泉窑更是形成了规模巨大的窑系,影响深远。浙江青瓷的出现可上溯至商代原始瓷,而商周时期的原始瓷窑址,主要分布在浙江北部以德清县为中心的东苕, 相似文献

伏俊琏先生是近年来在辞赋研究领域有突出贡献的学者。如果说《敦煌赋校注》、《敦煌文学文献丛稿》已奠定了他在辞赋研究领域的学术地位的话,那么新近由中华书局出版的《俗赋研究》一书作为伏俊琏先生辞赋研究的最新学术成果,则把辞赋研究尤其是俗赋研究又向前大大推进了一步。 相似文献

镇压反革命运动历时一年说质疑 总被引:1,自引:0,他引:1
镇压反革命运动是建国初期与抗美援朝、土地改革并称的三大运动之一,也是国史研究中的重要课题。关于这场运动起止的时间,目前的党史和国史的权威著作多持一年说。较早提出这个说法的是胡绳主编的《中国共产党的七十年》,认为镇压反革命运动从1950年10月发动,到1951年10月基本结束。何沁主编的 相似文献

发达国家工业化中期阶段经济增长与工业结构变化的特征 总被引:4,自引:0,他引:4
本文通过对几个发达国家的工业化过程和按收入水平分组的截面分析表明,工业化中期阶段具有增长加速、技术进步加速和重化工化使各发达国工业结构相似系数提高的特征。工业化中期经济增长的加速动力主要来自于积累的迅速提高和结构的快速转变两个方面。技术进步加速则表现为经济增长方式由外延粗放型向集约效益型的转变。和工业化初期的加速一样,工业化中期阶段的增长加速也是主要依赖于制造业的高速增长。但与之不同的是,工业化中期阶段的经济增长主要依赖于重化工业增长的带动,而不是轻工业的带动。此阶段还是工业内部结构变化剧烈的时期。 相似文献

Plant residues recovered from prehistoric stone artifacts can be used to help explain tool function and plant use. At the Changning site in Qinghai Province, Northwest China, dating from 4000 yr BP, we examined starch granules extracted from three slate stone knives. A total of 153 starch grains were retrieved from three stone knives, from which we identified starches from legumes, the Triticeae tribe, foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), roots and tubers. These results indicate that the stone knives may have been used for a variety of activities that included reaping grasses and food processing. The species of starch grains retrieved from the study sample reveal that diverse crops were cultivated at the Changning site 4000 years ago. 相似文献

To clarify issues involved in problematic identification of ancient starch granules, we investigated suspected granules found in residues from a Neolithic grinding stone in north‐east China. The chemical compositions of suspected granules and modern starch granules were tested via SEM–EDS. The results show that the elemental composition of the suspected granules mainly comprises O, S and Ca, which is similar to the composition of calcium sulphate, but quite different from that of real starch granules, which show high levels of C and O, with very low level of other elements. The findings in this study act as a warning that tiny mineral granules may be misidentified as starch, and also indicate that the method of SEM–EDS can be useful to confirm the nature of suspected granules in ancient starch analysis. 相似文献
