美国史学的兼容并包与社会影响

史学要产生较为广泛的社会影响,很重要的一点,就是要通过兼容并包来促进史学形式多元化局面的形成,在一般情况下,只有形式的多元化,史学才能在更大程度上去影响社会。美国史学就是一个较好的例证。     

汉冶萍公司的钢铁销售与我国近代钢铁市场（1908-1927）

汉冶萍公司改制组建以来,其产品销售机构和规章制度逐步完善,并多方开展了营销活动;在钢铁煤焦矿石各种产品销售中,钢铁销售收入占据重要地位,构成公司运转常年经费开支的主要来源;但当年国内市场十分狭小,钢铁销售既被外国列强挤压,又受国内政府挟制（主要在钢轨销售方面）;而在国外主要对日销售中,更遭其百般盘剥打击,致使我国惟一一个钢铁煤焦联合企业被迫沦为单纯为其供给铁矿石的开采机构。

农事节律与江南农村地区饮食习俗

一、引言长期以来,饮食问题一直是学界研究的重要课题之一。单就人文社会科学来说,如民俗学、历史学、人类学等都曾对这一问题有所涉及。在这其中,民俗学主要从饮食民俗的角度展开讨论。所谓饮食民俗:"是指有关食物和饮料,在加工、制作和食用过程中所形成的风俗习惯及礼仪常规。"其包含有多方面的内容,如年节食     

Estimating the number of components in an OSL decay curve using the Bayesian Information Criterion

The optically stimulated luminescence (OSL) decay curve is assumed to consist of a number of first-order exponential components. Improper estimation of the number of components leads to under-or over-fitting of the curve under consideration. Hence, correct estimation of the number of components is important to accurately analyze an OSL decay curve. In this study, we investigated the possibility of using the Bayesian Information Criterion to estimate the optimal number of components in an OSL decay curve. We tested the reliability of this method using several hundred measured decay curves and three simulation scenarios. Our results demonstrate that the quality of the identification can be influenced by several factors: the measurement time and the number of channels; the variability of the decay constants; and the signal-to-noise ratios of a decaying component. The results also suggest that the Bayesian Information Criterion has great potential to estimate the number of components in an OSL decay curve with a moderate to high signal-to-noise ratio.

洛阳新发现西汉画像砖

1996年洛阳市第二文物工作队征集一批汉画像砖.画像依题材分为10种,有车骑出行、山林狩猎、凤鸟与人物、兽斗、驯虎、龙、蟾蜍、玉兔、西王母等.画像砖时代为西汉晚期.这批汉画像砖的发现,为研究洛阳地区的汉画像砖艺术提供了新资料.     

纸质藏品修复用水考量

本工作借鉴已有的研究成果,并辅以相关调研,试图探究修复用水选择的重要性以及如何选择修复用水的问题。为此,通过对国内外文献的分析以及相关问题的调研,综述了生活饮用水中对纸张长期保存有害的污染物及其对纸张纤维的危害。通过对修复用水实例的讨论,指出:纸质藏品的修复须采用净化水,即通过逆渗透、去离子处理等方法净化后并达到一定电阻率的纯水,在条件许可的情况下,采用电阻率更高的超纯水更好;须现制现用以保证使用过程中净化水不被再次污染;在设备方面,选择小型纯水系统更能保证用水质量。     

Evidence for a Neolithic Age fire-irrigation paddy cultivation system in the lower Yangtze River Delta,China

Establishing stable cropping systems was vital in antiquity, assuring certain yields and enabling ancient people to settle, thus possibly causing various modern food habits and culture to form around the world, especially in cereal-cultivation-dominated countries. China, one of the most famous ancient agricultural countries, has a long history of rice planting, and the fire-irrigation paddy cultivation system is prevalent in the lower Yangtze region, which is considered a rice domestication center. However, its origin and cultivation pattern remain unclear. We studied a famous agricultural vestige, the Chuodun site, involved in rice planting in the lower Yangtze River Delta in eastern China, during the Neolithic Age. Clear evidence from archaeology, paleobiology, pedology and biogeochemistry suggest both that the rice fire-irrigation cultivation system formed during the Neolithic Age and that ancient peoples lived there steadily. Under this extensive cultivation system, soil structures and properties changed significantly; in particular, it left more black carbon in the soil and increased the organic carbon soil stability, which can be used to reconstruct prehistoric environments. Meanwhile, the prevalent fire-irrigation paddy cultivation system used by farmers in this area, though for a different purpose than ancient people, may be inherited from the Neolithic Age.
