广西地区汉代窑址的发现与初步研究

近年来，随着考古工作的深入，广西地区已发掘出众多的汉代窑址。其汉代窑业有着其独特的发展轨迹，在西汉早中期多受本土原有技术影响，发展较为缓慢，到了西汉后期，窑业多受外来技术影响，窑业技术迎来较大发展。本文从广西地区目前发现的汉代窑址考古资料出发，总结出了陶窑的基本形制及其产品主要特征，最后探讨广西汉代窑业技术源流。     

釉里红、颜色釉之概述

引言:"新平冶陶,始于汉世",意指景德镇的陶瓷业始于汉代,东晋以后渐有名气。唐代景德镇著名的"陶窑"和"霍窑"生产的瓷器就已经名闻天下,《景德镇陶录》记载其釉色之美:"陶窑…色素润…称为假玉器"。"霍窑…窑瓷色亦素…佳者莹缜如玉"。自此,"以釉取胜"的工艺装饰逐渐盛行。景德镇的釉里红、颜色釉的诞生、演变与发展由此开始。一、釉里红的概念、装饰方法及特征     

柴窑、柴器、钧窑及其他

柴窑不是“仙器”!归纳历代对柴窑的评价．受历史条件和生产工具的制约柴窑产品应有的特征。钧窑、汝窑发展了柴窑的制瓷技术。汴京官窑当与柴窑是同一窑址．这是因宋徽宗“崇古尊古”性格所决定的!     

淄博窑简述

正1窑址概况根据考古调查及发掘证实,淄博古窑址分布于山东淄博市淄川区和博山区境内[1]。目前发现的主要遗址有寨里窑遗址、磁村窑遗址、大街古窑遗址、坡地村窑遗址、博山城区大街窑址、东顶村窑遗址等。年代自北朝至清代,其窑炉结构及烧造工艺也在持续的发展过程中发生了很大的变化。1.1北朝至隋代目前发现的唯一窑址是寨里窑遗址。该窑址位于淄博市淄川区城东十余公里,窑址范围较大。据推断,其窑址为北方典型的"馒头窑",同时由于     

唐代梅县水车窑与潮州窑的发展成因初探(下)

根据粤东韩江流域遗存为数不少唐代梅县水车窑与潮州窑古代陶瓷这一特殊现象，搜集实物资料，作为窑址发掘研究资料的补充，进行排比与辨别考证；并就唐代水车窑与潮州窑陶瓷生产的发展成因与技艺特色、潮州港作为唐代重要的对外贸易出口港形成的客观背景和海上“陶瓷之路”开拓的关系等作初步分析探讨。     

山西霍州窑的别名及相关问题考辨

霍州窑是指山西霍州烧造陶瓷的古代窑口,近年来关于霍州窑的研究不多,可能是由于地方窑口的缘故,较少引起业内学者的关注。霍州窑的别名陈村窑、霍窑、西窑、彭窑、土定是否准确,“彭均宝”是谁,“?金匠”是不是“戗金匠”,所有这些问题,历史记载寥寥无几并且语焉不详,经考证认为霍州窑的别名有待规范,“彭均宝”应为“彭君宝”,“?金匠”应为“金匠”。

试论“珠光青瓷”及外销(续)

(五)窑炉及烧制方法福建的窑炉类型在南宋以前属龙窑类型,宋元之际是鸡笼窑类型,明代以后则使用阶级窑。这“三型说”也同样适用于“珠光青瓷”。在同安汀溪窑、厦门东窑,碗窑,南安石壁窑,晋江磁灶窑,安溪桂瑶窑等地均发现龙窑遗址,而以同安汀溪窑龙窑为代表。汀溪窑址位于距同安县城7公里左右的上埔村附近。五条窑炉均分布在汀溪水库大坝内

南唐官窑？——繁昌窑窑址性质问题再探究

繁昌窑为地方区域性窑址,先后在发掘中取得了惊人的成果,但其窑址性质似乎并未完全被确认,通过描述国内对繁昌窑性质断定的研究及文献记载、绘画中的相关论断,结合五代南唐社会背景和文人对艺术文化的独特审美,再次为繁昌窑窑址性质问题研究提供新的探究角度。     

佛山市顺德新城区降水中污染物的监测和分析

为掌握佛山市顺德新城区降水中污染物的情况,2015年7月至8月,文章作者分别在雨天进行了降水取样,对降水中的pH、电导率、常见阴离子(F-、Cl~-、NO_3~(2-)、SO_4~(2-))及部分重金属(铅和镉)进行监测分析。选择有相关数据的珠江三角洲和石家庄、厦门等地的降水中污染物的情况进行对比。结果表明,顺德新城区降水中的p H和部分阴离子浓度优于珠江三角洲平均值,酸雨类型属于硫酸和硝酸混合型;其水体洁净程度略差于石家庄;铅和镉的浓度也高于厦门,甚至部分超出了人体能直接接触的安全范围。     

Metabolism of trideuterated iso-lignoceric acid in rats in Vivo and in human fibroblasts in culture

Saturated very long chain fatty acids (fatty acids with greater than 22 carbon atoms; VLCFA) accumulate in peroxisomal disorders, but there is little information on their turnover in patients. To determine the suitability of using stable isotope-labeled VLCFA in patients with these disorders, the metabolism of 22-methyl[23,23,23-²H₃]tricosanoic (iso-lignoceric) acid was studied in rats in vivo and in human skin fibroblasts in culture. The deuterated iso-VLCFA was degraded to the corresponding 16- and 18-carbon iso-fatty acids by rats in vivo and by normal human skin fibroblasts in culture, but there was little or no degradation in peroxisome-deficient (Zellweger’s syndrome) fibroblasts, indicating that its oxidation was peroxisomal. Neither the 14-, 20-, and 22-carbon iso-fatty acids nor the corresponding odd-chain metabolites could be detected. In the rat, the organ containing most of the iso-lignoceric acid, and its breakdown products, was the liver, whereas negligible amounts were detected in the brain, suggesting that little of the fatty acid crossed the blood-brain barrier. Our data indicate that VLCFA labeled with deuterium at the ω-position of the carbon chain are suitable derivatives for the in vivo investigation of patients with defects in peroxisomal β-oxidation because they are metabolized by the same pathways as the corresponding n-VLCFA. Moreover, as iso-VLCFA and their β-oxidation products are readily separated from the corresponding n-fatty acids by normal chromatographic procedures, the turnover of VLCFA can be more precisely measured. A preliminary report of part of this work (Reference 18) was presented at the 5th International Symposium on the Synthesis and Applications of Isotopes and Isotopically Labelled Compounds, Strasbourg, France, June 20–24, 1994.

Denitrification in shallow groundwater in a coastal agricultural area in Japan

In a coastal agricultural area in the central part of Japan (Shizuoka), we found decreasing nitrate concentration with depth in a shallow groundwater, where the depth to water table varied between 0.6 and 1.2 m below ground surface. High nitrate concentrations (5–29 mg N L^–1) were often observed in the upper layer (0–2 m) of the groundwater, but the concentration decreased to less than 1 mg N L^–1 in the deeper layer. Ammonium was scarcely detected, and the concentration of dissolved oxygen was usually low (< 1 mgO₂ L^–1) in the groundwater. Nitrate in the groundwater often had very heavy nitrogen stable isotope ratios (>20{}). There was a negative relationship between nitrogen stable isotope ratio of nitrate and its concentration. When nitrate was injected into the groundwater with acetylene and bromide (a conservative tracer), nitrate concentration decreased to 20% of the initial level within 5 days, accompanied by the increase in nitrite and nitrous oxide concentration and a little change in bromide concentration. These results indicate that microbial denitrification plays a potential role in the decrease of nitrate in shallow groundwater at the study site.
