对秦兵马俑彩绘保护技术的思考与建议 总被引:2,自引:1,他引:1
秦陶俑彩绘保护是秦始皇陵保护的重点和难点。对秦兵马俑目前的现状进行全面介绍的基础上分析了损坏的原因,指出损坏是由历史、力学以及物理化学等原因共同造成。然后详细评价了PEG200和聚氨酯(PU)乳液联合处理的保护方法与单体材料渗透、电子束辐照固化(EB)的保护方法,并指出了这两种技术的优势及所存在的问题;还介绍了一些辅助加固技术并详细介绍了冷冻干燥法、盐溶液干燥法以及室温干燥法的原理和操作;之后提出了加固剂制备与陶俑保护一体化的设想、均匀场的设想以及稳定生漆层的设想。 相似文献

以湘南地区作为研究单元,多元化获取数据,运用“敏感-暴露-适应”分析框架和数理模型评价法对3种类型、6个村落的脆弱程度和致脆因素进行比较研究。结果表明:①务工型强脆弱、工贸型中脆弱、旅游型微脆弱;②旅游型和工贸型属复合E-A致脆类型,务工型属均衡E-A-S致脆类型;③务工型的敏感性远大于其他类型,民俗文化和村落居民是主要敏感因子;④旅游型为强暴露、工贸型为中暴露、务工型为微暴露。城镇化和旅游开发是主要暴露因素;⑤旅游型的适应性最高,工贸型次之,务工型最差;⑥不同类型村落的致脆短板因素差异较大。 相似文献

It is rare to find infant or neo-natal burials in the cemeteries of Roman Britain before the fourth century. There is evidence to suggest that it was as a result of the influence of Christianity that these small bodies came to be buried informal or designated cemeteries, rather than merely being disposed of in convenient pits or ditches, or under the floors or just outside the houses in settlements and towns. It would seem that the presence of neo-natal burials given the same burial rites as adults in a west—east cemetery carefully laid out to avoid intersection of graves or disturbance of other burials is a pointer to identification of the cemetery as Christian. 相似文献

The first Chinese Ordovician series was erected by Lee & Chao (1924). Since then, many regional Ordovician series and stage names have been established and mostly published in Chinese. The present study is a review of these regional units with a discussion of their definitions and correlation to the international standard. Among them, the Ichang series, Neichiashan series, Chientangkiang series, Yushanian stage and Dawanian Stage are most important; all regarded as regional stage divisions in China. The Lower, Middle and Upper Ordovician Series with their new definitions (Webby 1998) are now accepted in China. The global stage names, which have been approved (Tremadocian and Darriwilian), and “Caradocian” and “Ashgillian”, which are potentially to be part of the global standard, should be formally used in China. The Darriwilian Stage is defined in a global stratotype section near Huangnitang, Changshan, SE China. Only two regional stage names, the Yushanian and Dawanian, still remain since the international correlation of these two units has not yet been resolved. The main type Ordovician successions of China are identified, revised and regional correlations briefly outlined. 相似文献

1973年发现并开始发掘的浙江余姚河姆渡遗址,以距今7000余年前的精美黑陶,骨雕,干栏式建筑,稻谷等重大发现著称于世,曾入编中小学历史课本,并拍摄成彩色记录片,被苏秉琦先生赞为"一朵花"。当时农田水利建设迅猛发展的形势,这样一处内涵全新的新石器时代遗址,艰苦的生活条件,让发掘队员们经历了各种考验,但并没能击垮人们的工作热忱。同时这也是一处在那个年代备受瞩目和重视的遗址,第二次发掘伴随着"浙江省第一届亦工亦农考古训练班"的举办,对遗址进行了大面积揭露,每天在探方内作业的人员及农民工多达200多人,可谓浙江省考古发掘史上前所未有。在遗址发现即将迎来60周年之际,本文作者作为发掘者之一,执笔感念那个火热年代里的生活和工作,以为纪念。 相似文献

Chen, J., Beattie, R., Wang, B., Jiang, H., Zheng, Y. & Zhang, H., 12 April 2019. The first palaeontinid from the Late Jurassic of Australia (Hemiptera, Cicadomorpha, Palaeontinidae). Alcheringa 43, 449–454. ISSN 0311-5518.Palaeontinidae, an extinct group of large arboreal insects, has the most diverse record among the Mesozoic Hemiptera, but only a few taxa have been reported from the Southern Hemisphere. Herein, Talbragarocossus jurassicus Chen, Beattie & Wang gen. et sp. nov., one of the earliest representatives of ‘late’ Palaeontinidae, is described and illustrated from the Upper Jurassic Talbragar Fossil Fish Bed in New South Wales, Australia. This new taxon constitutes the first representative of Palaeontinidae in Australia and the first Jurassic example in Gondwanaland, providing significant distributional and stratigraphic extensions to the family.Jun Chen*?
