古耀州瓷着色元素的中子活化分析

运用中子活化分析(NAA)技术,测定耀州瓷釉中29种元素的质量含量,从中选取24种着色元素．通过对比分析,最后确定铁是耀州瓷的着色主元素,证明了考古界“耀州瓷以铁为着色主元素”的说法．

Fuzzy cluster analysis of the provenance of ancient Yaozhou porcelain body

The technique of neutron activation analysis (NAA) has been employed to measure the content of 29 kinds of elements in the sample of Yaozhou porcelain bodies,Then a fuzzy cluster analsis has been conducted to the NAA data and a diagram of the dynamic fuzzy cluster analysis has been achived,The results indicate that the batch of ancient Yaozhou porcelain bodies,which were of different overglaze color and were produced by different kilns during a period of over 800 years from the Tang Dynasty (618-907 A.D.) to the Yuan Dyansty(1271-1368 A.D.) ,has shared a stable and concentrated raw material source,Provenances of porcelain bodies from different times ,though having their specific independence ,enjoy a close relationship and are not far from one another,Provenances of porcelain bodies made during the Tang Dynasty and the Five Dynasties (907-960 A.D.)are found to be closer to one another,while those of the Song (960-1279A.D.) and the Jin Dynasty (1115-1234 A.D.)are comparatively concentrated in certain areas and are different from those of the Tang Dynasty .Both the tri-colored glazed pottery made in Yaozhou kilns during the Tang Dynasty and the Yaozhou porcelain bodies of the Tang period are from the same provenance.     

Application of ICP-MS trace element analysis in study of ancient Chinese ceramics

Chemical analysis plays a significant role in the study of ancient ceramics[1,2]. Most ancient Chinese kilns used clays mined from the local areas and differences in the geochemistry and mineralogy of these raw materials may be expected. The chemical composition of ceramics may also be influenced by production techniques, such as processing by washing and mixing of different sorts of raw materials. These may also vary from kiln to kiln and even change over time. Thus the raw materials and pro…     

Pitfalls in the analysis of ancient human mtDNA

The retrieval of DNA from ancient human specimens is not always successful owing to DNA deterioration and contamination although it is vital to provide new insights into the genetic structure of ancient people and to reconstruct the past history. Normally, only short DNA fragments can be retrieved from the ancient specimens. How to identify the authenticity of DNA obtained and to uncover the information it contained are difficult. We employed the ancient mtDNAs reported from Central Asia (including Xinjiang, China) as an example to discern potentially extraneous DNA contamination based on the updated mtDNA phylogeny derived from mtDNA control region, coding region, as well as complete sequence information. Our results demonstrated that many mtDNAs reported are more or less problematic.Startim, from a reliable mtDNA phylogeney and combining the available modern data into analysis, one can ascertain the authenticity of the ancient DNA, distinguish the potential errors in a data set, and efficiently decipher the meager information it harbored. The reappraisal of the mtDNAs with the age of more than 2000 years from Central Asia gave support to the suggestion of extensively (pre)historical gene admixture in this region.     

农业技术进步对中西方历史灾荒的影响

中西方灾荒历史灾荒均产生了严重的社会后果，在灾荒威胁下，农业技术水平、农业生产结构、农业发展状况等因素方面存在的差异直接影响到自然灾害的成灾后果。农业技术的进步在预防和控制灾荒的活动中发挥了重大作用，中国传统农业科技在一定程度上控制了灾情的蔓延，减轻了灾害的破坏和威胁；也是由于农业技术的落后，欧洲农业遭受灾荒后往往一蹶不振。中国农业发展的整体一致性既有利于技术的普及推广和传播，但也为农业灾荒的发生创造了条件。

对三峡江南入蜀古道的有关认识

长江三峡南岸入蜀古道，是除三峡水道外又一入蜀的重要陆路通道。此道东起湖北宜昌市江南点军区姜诗溪口，西至利川市谋道苏拉口，全长500公里，东连着丰饶的荆楚大地，西可通往“天府之国”的川西平原，20世纪70年代修建的318国道路线大致上走的就是三峡南岸的西行人蜀古道。古道始筑于商周时期，沿用于秦汉以后一直到现在。历史上每到朝代更替之际，它都被用作军事通道，而太平盛世之时，它又成为社会经济发展中的交通生命线。在古道上遗留下来的一些遗址、墓葬、窖藏、桥梁、石碑、石板路等各类古文化遗迹向我们叙述着昔日商旅、驿差、军队、部族人群等在古道上往来奔波的繁忙图景。
