Review and assessment of the potential of post-IR IRSL dating methods to circumvent the problem of anomalous fading in feldspar luminescence 总被引:2,自引:0,他引:2
Quartz has been the main mineral used for optically stimulated luminescence (OSL) dating of sediments over the last decade. The quartz OSL signal, however, has been shown to saturate at relatively low doses of ~200–400 Gy, making it difficult to be used for dating beyond about 200 thou-sand years (ka), unless the environmental dose rate is low. The infrared stimulated luminescence (IRSL) from feldspars has been shown to continue to grow to higher dose levels than quartz OSL. The application of IRSL dating of feldspars, however, has long been hampered by the anomalous fading effect. Recent progress in understanding anomalous fading of the infrared stimulated luminescence (IRSL) signals in potassium-feldspar has led to the development of post-IR IRSL (pIRIR) protocols and also a multiple elevated temperature (MET) stimulation (MET-pIRIR) protocol. These procedures have raised the prospect of isolating a non-fading IRSL component for dating Quaternary deposits containing feldspars. In this study, we review the recent progress made on (1) overcoming anomalous fading of feldspar, and (2) the development of pIRIR dating techniques for feldspar. The potential and problems associated with these methods are discussed. 相似文献

The Changsha Street Corps originated in the local militia during the period of the Taiping Rebellion, and it played an important part in Changsha’s urban social management at the grassroots level. However, the role and influence of the street corps underwent changes during the process of modernization and the building of the modern nation–state. By 1920, although the street corps of Changsha still worked as the agent of the state at the grassroots level, its autonomy had been curtailed, and its social influence weakened. In the new social environment, even the maintenance of neighborhood interests became a challenge for the street corps. This article illustrates the readjustments in geopolitical and industrial relations during the process of urban modernization. It also illustrates how a new form of state power, namely the police, infiltrated the social management system, affected the traditional social structure, and complicated the interaction between modern state and society. 相似文献

采用光学显微观察、激光拉曼、紫外-可见吸收光谱以及高效液相色谱对河北隆化鸽子洞蓝棉袄蓝色、浅蓝色纤维以及百衲枕顶蓝色纤维进行分析研究.通过多种分析手段相互佐证表明,该组样品采用蓝草中的靛蓝染色,色素成分有靛蓝素和靛玉红.各样品中色素成分比例均不相同,推测至少在元代,人类已经能够有意识地调整制靛工艺,染出自己需要的色光.同时靛蓝染料耐光性耐热性差,对酸、碱和氧化均敏感,耐盐性及耐细菌性较弱.在以靛蓝染色的织物清洗中,要选择性地使用洗涤剂,进行点滴试验后才可使用,同时在存放过程中要做到避光、避免高温. 相似文献

Tibetan armament has a long history that is heavily influenced by the culture of Central Plains. An important part of the Chinese culture of armaments, they also retain their uniqueness and interrelationship. In Tibetan historical records written in the Ming Dynasty, there were detailed accounts of swords. In general, Tibetan armaments advanced substantially during the Tang Dynasty by learning from the Tang. 相似文献

在每个封建王朝濒临灭亡与新的王朝建立之时,总有一批作家,由于这样或那样的原因被遗忘在历史的角落,当今天我们再一次谈起这些作家时,首先必须面对的两大问题就是:作家的朝代归属与作品的辑录考证,在此仅以元代杭州作家董嗣杲为例,对这两个问题作一简单分析. 相似文献

华侨高等教育是我国高等教育独特而又不可或缺的重要部分,她的产生、形成、嬗变和发展经历了相当长的一段历史。在这段长期的历史进程中,民国时期是华侨高等教育兴起与发展的重要时期。国民政府将暨南学校升格为国立暨南大学,开辟了华侨高等教育新的纪元。政府对一所高校的举措,从一个重要侧面反映了当时社会政治、经济、文化和教育的状况。研究暨南学校走向国立暨南大学,华侨基础教育发展成为华侨高等教育的内在因素和外在条件,探讨侨务政策与华侨教育之间的关系,对于认识与改进今日之华侨高等教育有着很大的现实意义。 相似文献

唐代前期都督府探讨 总被引:1,自引:0,他引:1
李青淼 《中国历史地理论丛》2006,21(4):66-77
有鉴于前人对唐代都督府认识的分歧,本文从文献的角度论证了今人观念下的都督府自唐代建立至安史之乱的不同职能,即军政职能、民政职能、监察职能。并重点阐述了前两种职能所依据的社会背景,二者之间的相互转化,以及三种职能下都督府与常州之关系,力图解决困扰都督府研究的一些问题。 相似文献
