由于暖气管道爆裂,造成中国民族图书馆馆藏的大量珍贵文献被热水浸泡或熏蒸。为了赶在天气转暖之前抢救完这批文献,综合运用了常见的几种水湿文献的抢救方法,特别借用了文物界所常用的低温干燥法,用3个月的时间,完成了全部水湿文献的抢救重任,为以后的系统修复工作奠定了良好基础,同时也为图书馆界抢救文献提供了一些可供参考的经验教训。实践证明抢救大批量的水湿文献应从实际情况出发,及时调整方案,从长计议,综合运用各种抢救方法,随时总结经验教训,才能在有限的时间里最大程度地抢救受损文献。  相似文献

Forty-five years ago Timothy Thompson excavated at two of the six mounds at the Garden Patch site but results were never reported. We assembled data from Thompson's work and enhanced them with new test pits at Mound IV and re-excavation of a Mound V trench. Mound IV is a natural sand ridge where a village was established early, by the second century A.D. Mound V began as a naturally elevated platform for at least one burial and associated structure during the fourth century A.D. and was then covered by lenses of shell and sand. The construction sequence of Mound V resembles other mounds in the region. These results help illuminate the functions and depositional histories of mounds within Woodland multi-mound centers of the coastal plain while also demonstrating an effective approach to balancing stewardship and new excavations.  相似文献
