Miscellaneous Artifacts From Casselden Place, Melbourne

The miscellaneous artifacts from Casselden Place derive from an urban working-class community in nineteenth-century Melbourne, Australia. They include a broad range of items associated with work, recreation, education, fashion, food consumption, health, and other facets of everyday life. In this paper the miscellaneous assemblage is examined in light of research questions relating to health and hygiene, leisure and work, and access to luxury items amongst the working-class of the mid to late nineteenth century.     

试论文物摄影的表现方法

文物摄影是摄影艺术的一个门类 ,除了要注重科学性和真实性外 ,还要强调其艺术性和欣赏性。本文从拍摄角度、背景处理、光线运用等几个方面论述了文物摄影的表现方法。     

细菌纤维素对木质文物修复的初步探索

为研究细菌纤维素对木质文物的修复效果,首先检测了产纤维素的醋杆菌Acetobactersp．PDA静置培养时的生长,然后将其与小块的饱水木材一起静置培养,通过测定木块处理前后的湿重及扫描电镜观察,结果显示细菌纤维素对木质文物有一定的修复作用。     

Effects of distance from stone source on landscape-scale variation in Oldowan artifact assemblages in the Paleo-Olduvai Basin,Tanzania

Ongoing excavations at Olduvai Gorge, Tanzania, reveal tremendous variability among stone artifact assemblages across the Plio-Pleistocene Olduvai Lake Basin during Bed I and lower Bed II times. Theoretically, stone artifact traces of Oldowan hominin land use are determined by the distribution of larger mammal carcasses and arboreal refuge from predation as well as proximity to stone material sources.     

安徽省南陵县江木冲古铜矿冶炼遗物自然科学研究及意义

本通过对江木冲冶炼遗址古铜矿、古炼渣、古铜锭及青铜器的对比研究,利用矿床学、冶金学等理论,探索利用自然科学手段解决其输出路线问题,提出了判别其产物(铜锭)的特征微量元素和其它综合判别标志,同时也为青铜器其它矿料来源(尤其锡矿)难题的解决进行了技术路线探索和方法研究。     

珂罗版复制在书画文物保护中的作用

珂罗版印刷是一种古老而精妙的平面印刷技术,珂罗版印刷在印刷复杂的书画作品时,特别是在中国古代书画的笔触和墨韵表现上,可以最大限度地体现原作的艺术特色,达到其他印刷手段难以企及的艺术境界。珂罗版印刷与人工设色相结合,提高了人工临摹的工作效率使古老珂罗版印刷更具艺术生命力,成为复制书画文物的最佳手段。     

氯离子选择性电极测定铁器碱性脱盐溶液中 氯离子的含量

在铁质文物的保护过程中,脱盐是重要的保护程序之一。通常铁器的脱盐溶液为碱性。本工作主要研究氯离子选择性电极法在测定碱性脱盐溶液中的氯离子含量时,溶液pH值和复配溶液中的表面活性剂对测定结果的影响。实验结果表明:(1)用氯离子选择性电极法测定碱性脱盐溶液或复配碱性脱盐溶液中的氯离子浓度是可行的;(2)溶液的pH值对测量结果有一定的影响,当溶液pH值在2～7范围内时,其对电位值影响不大;(3)表面活性剂对测量结果影响较小,在实际应用中,应配制与待测溶液组分相同的氯离子标准溶液,后期数据处理并绘制标准曲线,以使测量结果尽可能接近实际值。精密度和回收率实验表明,该方法准确度满足定量分析的要求。由此可见,当脱盐溶液为碱性NaOH或复配碱性NaOH溶液时,用氯离子选择性电极实时监测脱盐溶液中的氯离子含量能较好地反映器物脱盐程度。     

Lead ingots from a shipwreck Off Poompuhar, Tamil Nadu, East Coast of India: evidence for overseas trade and their significance

Various types of lead ingots have been reported from a number of shipwrecks from different parts of the world. In 1991 exploration of a wreck off Poompuhar, Tamil Nadu, East Coast of India, at a depth of 19 m yielded a gun, rudder gudgeon, gunpowder boxes and a variety of lead ingots. The most significant ingots are those marked W: Blackett and D with a crown symbol on the obverse and 1791, 1792 and some merchant marks on the reverse. These are similar to Blackett lead ingots found in England, the Netherlands and Sumatra. Pb-isotopic analysis has revealed their source as the North Pennine lead mines of England. Further, the lead used was of high purity -93%. Records show that Blackett was a well-known lead-exporting company in England since 1694. The wreck off Poompuhar may be a Toni type cargo ship carrying traded lead ingots of different manufacturers.
