纳他霉素在丝织品上的抑菌实验研究

为了筛选出能用于丝织品文物防霉且对人、环境安全的生物代谢产物,选用目前在国际上得到广泛认可的安全性防霉剂纳他霉素,在一定的光照条件下,采用抑菌圈法对现代天然丝织品材料进行了防霉试验。结果表明,无论是否以乳酸链球菌素作为助剂,500μg/g(以有效成分计)纳他霉素在丝织品上防黑曲霉、青霉、毛霉效果明显。纳他霉素对白色丝织品的色泽和机械强度无破坏性影响。纳他霉素在丝织品文物防霉上有应用前景。     

浅析广西西林县普驮铜鼓葬

广西西林县普驮发现的“铜鼓葬”是古句町一种较为特殊的葬俗,时代为西汉晚期至东汉初,其特殊的葬俗、独特而丰富的随葬品,暗示此类葬俗是专为某类特殊的人群使用。我们认为西林普驮铜鼓葬的主人身份是句町部落集合体中具有显赫权威的精神领袖－巫师。     

云南洱海地区石棺墓初步研究

石棺墓是利用石板或石块制作成葬具,以埋葬死者的一种埋葬形式,它是云南西部地区古代民族常见的一种埋葬习俗。洱海地区是云南发现石棺墓最集中与最丰富的地区,该地区包括今禄丰县、楚雄市以西,洱海以东,金沙江以南,哀牢山以北这一广大地区。发现石棺墓的主要地点有姚安县黄牛山、寨子山,宾川县古底;大理市海东,     

商末黄河中游气候环境的变化与社会变迁

新石器时代到商代黄河流域的气候属于温暖湿润期;商代后期气候出现厂干旱化,导致了古公亶父迁岐,文王迁程迁丰,帝乙帝辛时不断向南方发展;而商末的旱灾和饥荒是周武王克商的直接导火索,导致商周之际的改朝换代。商末气候环境的变迁对其时社会政治的影响极大。     

Reconstructing subsistence at the Yingpanshan and Gaoshan sites in Sichuan province,China: Insights from isotope analysis on bone samples and charred crop remains

During the Neolithic period, the Chengdu Plain was a key region where two important crops, rice and millet, were cultivated together. Millet was probably introduced from north-western China c.3500–3300 cal. bce , and rice came from the Middle Yangtze River c.2600 cal. bce . In this study, human and faunal remains, as well as charred crop grains, were collected from the Yingpanshan (3300–2600 cal. bce ) and Gaoshan (2500–2000 cal. bce ) sites where the dominant crop was millet and rice, respectively. Carbon and nitrogen isotope analyses were conducted on human bones and the ecofact samples in order to reconstruct the subsistence at the sites. The results indicate that the diets of two individuals recovered from the Yingpanshan site consisted of both C₃- and C₄-based foods, predominantly the former. By contrast, Yingpanshan pigs consumed a large quantity of C₄ fodder. This result, combined with the ecofact evidence, suggests that millet was the main crop at the Yingpanshan site. It also highlights the fact that the two Yingpanshan individuals might be non-locals and/or belonged to later periods. On the other hand, the diet of the Gaoshan community was dominated by C₃-based foods. When considering the archaeobotanical evidence at Baodun, a site contemporaneous with and near to the Gaoshan site, it can be stated that rice was an important food resource for the Gaoshan community. This study also suggests how crops were managed at the two sites. The Yingpanshan people might have used manure for growing millet. Both manuring and irrigation might have also been practised by Gaoshan's rice farmers. However, more studies are required to understand the extent of manuring and irrigation in their agricultural economies.

嘉道年間江南的漕弊

嘉道年間的漕務是與積弊聯繫在一起的,作爲一種常態而存在的漕弊,本身即是制度的組成部分。在財政層面,漕弊主要表現爲旗丁幫費問題、大小户問題、漕糧的浮收勒折與虧空問題。嘉道年間的江南,一方面是倉漕衛所規費、旗丁幫費、官紳漕規、州縣浮收逐年遞增,而另一方面,捏災、短漕、虧空也隨之愈演愈烈,這導致了漕糧河運制度在道咸之交的崩潰。本文認爲:從財政結構的角度來看,所謂漕弊是各種"浮費"代表的額外財政對於額定財政的空前侵蝕。     

蒙特利尔“民族岛”的空间结构

在我国关于城市地理的研究成果已经相当丰富,但是将文化地理与城市地理相结合的研究尚不深入,笔者在完成加拿大政府ＦＥＰ项目所资助的“加拿大文化地理”课题时,受北美地理学家影响,对加拿大许多城市中的“民族岛”进行了调查。“民族岛”的概念为国外学者创造,在近些年来出版的汉译人文地理著作中和国内学者编著的人文地理、文化地理著作中,已对“民族岛”作了粗略的介绍。“民族岛”是指在城市或乡村中某一民族的聚居区,这一聚居区必须在文化的内外特征上与其周围地区有鲜明的区别。本文拟以加拿大蒙特利尔“民族岛”的产生、分布和形成原因,引出城市地理和文化地理研究中应予重视的新角度
