三国时期吴蜀夷陵之战,是一个决定双方强弱、动摇三分局面的大战役。战争的起因是:公元219年,孙权乘蜀魏交兵襄樊、南郡空虚之机,派吕蒙偷袭江陵,擒杀关羽,全据荆州。公元221年,刘备“耻关羽之没”,率众四万余人伐吴,吴以陆逊督师五万御之,两军对垒于夷陵。最后,陆逊以火攻破蜀兵四十余营,“备夜遁,仅得入白帝城。其舟船器械水步军资,一时略尽”。弄得实力大伤益州疲惫,蜀汉政权严重削弱。在刘备起兵之前,“群臣谏者甚众,汉主皆不听。广汉处士秦宓 相似文献

三国时期,孙权继承父亲孙坚和哥哥孙策打下的基业,据有江东,建立吴国,史称“东吴”,孙权就是吴国的开国皇帝。这样一来,孙权就成了当时吴国最高层的领导人。但是,作为一个国家的最高领导人,孙权这个人的性格中有着好几个重大的缺点,这些缺点对于吴国各项事业的发展产生了消极的影响。 相似文献

繁昌汤家山西周墓是一座高等级的吴国墓葬。通过对长江下游西周至春秋时期吴国墓葬的等级规模和出土青铜器的比较研究,汤家山西周墓与丹徒烟墩山、荞麦山西周墓和北山顶、青龙山春秋墓属同一等级的墓葬,皆为吴王之墓;根据汤家山西周墓主身份和墓地位置推测,《左传》记载的"鸠兹"应为西周晚期的吴国都城。 相似文献

This article examines how the practice of learning geography, and the arenas in which knowledge-making takes place, can be usefully positioned within changing histories of the discipline. It contends that networks of action – understood through the intersection of social sites, subjects and sources – present a conceptual framework and narrative focus for the re-consideration of specific episodes from geography's past. The interventions made here are informed and illustrated by a 'small story' about the doing of geography. Based on different personal accounts, the story revives a series of events, encounters, dialogues and images dating back to the winter of 1951 at Glenmore Lodge, Scotland. This educational institution in the Cairngorm mountains offered children from urban areas the opportunity to learn field studies and the skills of 'outdoor citizenship'. Initially, the focus falls on Margaret Jack, a 14-year-old field-course participant. Her learning experiences are traced through personal letters, a diary and a field journal dating from that time, and her recent recollections of this event. Margaret's account dovetails with the story of her field studies instructor, Robin Murray. Robin's role is traced through his learning experiences as a geography undergraduate at Aberdeen University, and the recent recollections of Catriona Murray, his wife. 相似文献

The Knowledge of Debt: Law, Media Technique, and Everyday Experience in Liberal Capitalism. Performing an object such as ‘the economy’ hinges on practices of formatting knowledge. The article proposes to look at such instituting moments in connection with social conflicts over the legitimate rules of exchange. This is exemplified by way of recounting the story of the codification of Swiss bankruptcy law in 1889. In order to homogenize the legal procedures of debt collection and bankruptcy, two subject categories were instituted: ‘merchants’ and ‘non-merchants’. These different categories were thought to account for the diverging temporalities and spaces of credit exchange in everyday economic life. The introduction of the commercial register, a media-technical apparatus, enabled a formal distinction between ‘merchants’ and ‘non-merchants’. However, this boundary was contested and proved to be porose. 相似文献

Shells of two species of freshwater bivalve (Unio willcocksi Bullen Newton and Etheria elliptica Lamarck) from the predynastic Gerzean (Nagada II) Decorated Tomb at Hierakonpolis, Egypt have given dates of 5000±90 bp for the tomb, and 12,900±120 bp for an episode of Nile terrace accumulation (correlated here with the Sahaba-Darau aggradation event). The archaeological and geological significance of these results is discussed, together with an outline of problems associated with radiocarbon dating of shell. Comparisons are made with the few other radiocarbon dates available for the Predynastic period in Egypt and possible reasons for the presence of shells in the tomb are considered. 相似文献

The later post-glacial history of a valley in the chalk escarpment near Brook, Kent, is described, based on molluscan stratigraphy, archaeological evidence and radio-carbon dating. Differences in size and colour banding, respectively, of fossil and living representatives of two species of land snails, Pomatias elegans (Müller) and Cepaea nemoralis (L.), are correlated with climatic change during the post-glacial period. The problems of the use of fossil shells of these species as samples for radiocarbon dating are discussed. 相似文献

A Singapore-based economic geographer explores and analyzes the spatially uneven evolution of the Internet industry in China, arguing that the country's immense regional disparity in the provision of Internet services is best explained by the interplay of place- and path-dependence. The author demonstrates how the highly uneven regional endowments in relevant industrial and entrepreneurial resources have led to the substantial and persistent regional imbalance within China's emerging "new economy." His initial survey of the country's 100 leading Internet content providers (firms), identified from a listing of ca. 11,700 commercial websites, is selectively augmented to reflect an increase of over 70 million Internet users in 2007, reaching a total of 253 million in June 2008, and thus overtaking the United States as the world's largest Internet market.

This paper discusses the 1911 International Exposition in Rome and illustrates how this patriotic celebration of the fiftieth anniversary of the Italian Sate utilized symbolic landscapes of architecture and archaeology to promote nationalist sentiments of italianità and romanità centered on the young capital of Rome. Through modern art exhibitions at the Valle Giulia, scientific conferences at the Castel Sant’Angelo, archaeological exhibits on the Roman Empire in the Baths of Diocletian, and regional Italian pavilions in the Piazza d’Armi, exposition officials offered a complex representation of Italian national identity that was modern yet ancient, cosmopolitan yet bucolic, European yet regional, and imperial yet developing. 相似文献

Alexander the Great died in 323 B.C. from an unknown cause. By elucidating the nature of his death, we can better interpret various aspects of Alexandrian history. Alexander’s death may have ensued from the sequelae of a congenital scoliotic syndrome. It would therefore be of significance to note that one of the greatest leaders in history who conquered much of the then known world may have been suffering from a physical disability. 相似文献

Der Denkstil der Chemiker. Der Aufsatz diskutiert die Tragfähigkeit des Begriffes “Denkstil”, wie er von Alistair Crombie eingeführt und Ian Hacking aufgegriffen wurde, für das Verständnis dessen, wie das Fach Chemie historisch seine Identität ausgeprägt hat. Obwohl weder Crombie noch Hacking den Begriff “Denkstil” in Bezug auf einzelne Disziplinen verwendet haben, erscheint im Fall der Chemie seine Anwendung besonders vielversprechend, weil er hier hilft, ein zentrales Problem zu thematisieren – nämlich die Frage, wie es Chemikern trotz wechselnder Gegenstandsbereiche und theoretischer Umbrüche gelang, eine eigenständige und stabile Identität auszubilden. Nach einer Einführung in den Begriff “Denkstil”, argumentiert der Aufsatz, dass die Beständigkeit der Chemie als eines Faches wesentlich in ihren Laborpraktiken gründet, die ihrerseits wiederum die spezifische Art der Fragen bestimmten, die Chemiker in ihren Forschungen stellten bzw. die Form der Antworten, nach denen sie suchten. Folgende Merkmale kennzeichnen diesen “chemischen Denkstil” (1) eine spezifische, im Herstellen begründete Form des Wissens, (2) die Befassung mit einzelnen Stoffen und Materialien statt mit Materie im Allgemeinen und (3) eine Beobachtung von Natur besonders im Hinblick auf Transformationsprozesse. The Chemists' Style of Thinking. This paper discusses the relevance of the notion of “styles of scientific thinking” introduced by Alistair Crombie and revisited by Ian Hacking, for understanding how chemistry shaped its identity. Although neither Crombie nor Hacking applied this notion to individual disciplines, it seems appropriate to use it in the case of chemistry because it helps to address a puzzling issue: how did chemists manage to shape an identity of their own, despite shifting territories and theoretical transformations? Following a presentation of the notion of style, I will argue that the stable identity of chemistry is rooted in laboratory practices, which determined the specific questions that chemists put to nature as well as the answers to their questions. The “chemical style of thinking” is characterized by i) a specific way of knowing through making, ii) the concern with individual materials rather than matter in general and iii) a specific commitment to nature. 相似文献
