Those reflections centre on the implications of the life and work of one of the past centuries most unusual intellectual figures Joseph Needham (1900-1995).  相似文献

王立达[1]说,"癌"是日本人创造的汉字.王说曾为一些学者所继承,如胡新化[2]等.然而,据黄金贵[3]、何华珍[4]考证,"癌"字最早见于宋东轩居士<卫济宝书>(1170年).<卫济宝书>是一本外科专著.其中卷七有"痈疽五发"之说:"一曰癌"、"二曰瘭"、"三曰疽"、"四曰痼"、"五曰痈",且附有图示.  相似文献

2006年5月20日,世界上规模最大的混凝土大坝——三峡大坝耗时3080天,终于全部建成了。国内的英文报刊和英文图书几乎都将“三峡大坝”英译为the Three Gorges Dam,初看似乎还可以,但仔细推敲起来就显得有些不足。三峡大坝应归类为地名,地名通常由专名和通名组成。“三峡”是专名,“大坝”是通名,值得探讨的是通名“大坝”。[第一段]  相似文献

It is shown that one can calculate the Hubert-Arabie adjusted Rand index by first forming the fourfold contingency table counting the number of pairs of objects that were placed in the same cluster in both partitions, in the same cluster in one partition but in different clusters in the other partition, and in different clusters in both, and then computing Cohen’s κ on this fourfold table. The author thanks Willem Heiser, Mark de Rooij, Marian Hickendorff and three anonymous reviewers for their helpful comments and valuable suggestions on earlier versions of this article.
