准“奥运之夜”

<正>这是可作准"奥运之夜"的一场比赛。秦皇岛是北京奥运会足球项目分赛场。此前,中国女足姑娘们一次次来到秦皇岛,在中国足球学校集训、在奥体中心场馆打邀请赛和测试赛。赛事多以中国女足取胜结束,因此这里被中国女足称为福地,秦皇岛市长朱浩文在北京奥运倒计时100天时,于天下第一关城楼下,授予中国女足姑娘们荣誉市民称号。     

满城皆标志,奥运秦皇岛

期待百年,北京奥运与盛夏8月如期约会。全世界的目光都聚集在中国,聚集在北京,也聚集在奥运协办城市秦皇岛。秦皇岛,中国北方夏都,以一种如火的激情早早地拉开了奥运序幕。

向世界展示中国力量

"中国何时能够派一名运动员参加奥运会?中国何时能够派一支运动队参加奥运会?中国何时能够办一届奥运会?"1908年南开大学众学子投书《天津青年》杂志,提出3个奥运追问,他们大概不会想到,对这3个问题全都给出圆满

都记住他们不容易!本期封面是众声喧哗中历史记忆的归纳和整理。对136位中国奥运冠军进行"全记录",策划和构思别出心裁,似乎也有不得已而为之的煞费苦心,幸好左邻右舍没有凑巧相似,在资料收集汇整,尤其是历史图片方面,画面和文字多有精彩,也算是别样的"鹤立鸡群"。强国梦和"去东亚病夫化"的过程,是将近一个甲子岁月的跌宕起伏和坚持不懈。     

唤醒沉睡的废墟——大遗址记忆的中国大历史扫描

我们的过去,都成为了历史。曾经的辉煌,曾经的精致,在历史的风雨中化作废墟,静静地沉睡在地下。 这些废墟经历了千百年乃至若干万年的风雨磨砺,昔日凝重的历史印记仍旧深深地铭刻在它们的上面。废墟变幻的本体,斑斓的色调,是一个时代、一族人群、一种文化留给后世的纪念。当考古人唤醒废墟的时刻,一段忘却的历史,一页缤纷的画卷,一曲悠远的长歌,便会豁然眼前,响亮耳畔。

中国古代神话的特色及其成因

中国古代神话是中国本土的产物,它深深地植根于中国悠久的文化土壤之中,渗透着东方智慧的光芒。诚如德国哲学家黑格尔所言,中国是个早熟的儿童,中国的古代神话就是中国这个早熟的儿童,通过神话的方式,对中国历代著名人物的思考与评价。中国古代的神话闪烁着理性的光芒,它有明确的指导思想,那就是尚德、尚功与尚智,着眼于著名人物对时代与民众的贡献,中国的古代神话与中国祭祀文化的精神实质是一致的。因而中国的古代神话,在世界各民族神话之林中,是独具特色的神话之一。     

《新修方志特色过眼录》之五(上)

百年沧桑上海县——录《上海县志》到目前为止,我所见到的新修方志内容最全面的恐怕要首推《上海县志》了。从其记载的内容来看,确实是在按照中国地方志指导小组所制订的《新编地方志工作暂行规定》办事。《暂行规定》曾明确要求:新编方志内容要“着重记述现代历史和当前现状”。这个要求应当说是从我国实际情况出发而提出的,因为这一段历史和现状,正是中国共产党领导中国人民推翻三座大     

对中国出土青铜器修复与保护方法的思考

中国古代青铜器是中国古代明的重要组成部分,以其丰富的铭、精美的纹饰及造型、高超的冶金和铸造技术及表面处理技术而闻名于世。大多数青铜器在出土时均有不同程度的损坏与腐蚀,因而需要对其进行修复与保护处理,以便于研究与陈列展出。     

Discrimination of Ceramic Surface Finishing by Vertical Scanning Interferometry

Finishing techniques are significant markers of the technological ‘know‐how’ involved in the production of the traditional, clay‐based ceramic ware. In order to provide a reliable tool to discriminate among two main surface processing techniques—that is, smoothing and burnishing—vertical scanning interferometry (VSI), a recently developed non‐destructive technique for analysing the surface roughness and topography, is applied. The smoothed areas have an obvious roughness expressed by linear structures. The latter are made of parallel ridges and trenches with an average depth of 15–20 μm. Burnishing leads to a lower topography and a lower roughness compared to the smoothed surface section. VSI quantifies the spatial distribution of the surface building blocks, which consist of phyllosilicate aggregates of variable size. The statistical treatment of the roughness data obtained by VSI shows that the surface topography provides significant information on the pottery processing and a clear qualitative and quantitative discrimination between different surfaces. VSI supports the reconstitution of the chaîne opératoire for traditional ceramic pottery and the recognition of the surface finishing techniques.     

Quantifying Interpolation Errors in Urban Airborne Laser Scanning Models

Airborne laser scanning (ALS) is becoming an increasingly popular data capture technique for a variety of applications in urban surface modeling. Raw ALS data are captured and supplied as a 3D point cloud. Many applications require that these data are interpolated onto a regular grid in order that they may be processed. In this article, we identify and analyze the magnitudes and spatial patterning of residuals from ALS models of urban surfaces, at a range of different scales. Previous research has demonstrated the effects of interpolation method and scale upon the nature of error in digital surface models (DSMs), but the size and spatial patterning of such errors have not hitherto been investigated for urban surfaces. The contribution of this analysis is thus to investigate the ways in which different methods may introduce error, and to understand the uncertainty that characterizes urban surface models that are devised for a wide range of applications. The importance of the research is shown using examples of how the different methods may introduce different amounts of error and how the uncertainty information may benefit users of ALS height models. Our analysis uses a range of validation techniques, including split-sample, cross-validation, and jackknifing, to estimate the error created in DSMs of urban areas.     

从青铜器纹饰看中国传统装饰美感

中国青铜器的发展主要经历了夏、商、周三个历史时期,其间青铜器的装饰风格从凝重庄严转向了朴实、简洁,同时青铜器的社会功能也从祭祀用的礼器逐渐转变成实用器具。青铜器的纹饰则由庄重的饕餮纹、夔纹到富有韵律的窃曲纹、环带纹,再发展为清新的蟠螭纹、宴乐纹、攻战纹等。     

Scanning electron microscopy of wood replaced by iron corrosion products

Remains similar to wood in superficial appearance are sometimes observed on the surfaces of corroded iron objects from archaeological deposits. Examination of this material in a scanning electron microscope suggests that deposition of iron corrosion products has occurred within the cell spaces. Subsequently the wood may have decomposed, leaving behind internal cell casts which mirror the original structure.

Non-invasive Archaeology of Skeletal Material by CT Scanning and Three-dimensional Reconstruction

The remains of an ancient Sumerian skeleton, approximately 7000 years old, were investigated using the techniques of stereolithography. The very fragile and delicate skeletal material was recovered in a block, thus retaining it in the soil matrix. The excavated block was CT-scanned and the skeletal material was rendered in three dimensions. This formed the basis for a stereolithographic model of the mandible, which was used for physical and dental anthropological studies. Skeletal remains may thus be made available for research without having to remove them from the local matrix, which may be an advantage in an archaeological or palaeoanthropological setting. © 1997 by John Wiley & Sons, Ltd.
