彭头山等遗址陶片和我国最早水稻遗存的加速器质谱~(14)C测年

本文介绍用加速器质谱碳十四测年(Accelerafor-mass-spectrometry—~(14)C)方法,简称AMS—~(14)C方法,直接测定古代陶片中各种含碳组分的年龄,并报道对湖南彭头山和胡家屋场两遗址陶片和我国最早水稻遗存的测年结果。这是北京大学考古系与牛津大学考古与艺术史研究实验室合作的成果。陶片的碳十四测年国内外还很少有系统的研究,它提供了新的可能,也提出了新的问题。     

三百红军遭残害 凶手竟是毒泉水

三百红军遭残害　凶手竟是毒泉水掌征美５８年前,中国工农红军冲破了国民党数十万大军的重重封锁与围追堵截,爬雪山、过草地,历经千难万险,终于征服了长征路上最后一道天险─－六盘山。然而,就在这胜利在望之际,却发生了３００多位红军将士暴死身亡的大奇案。１９３...     

香港地区青铜时代考古及有关问题的探讨

早在20年代初,就有港英政府的官员、医生、传教士等外籍人士在香港从事考古调查与发掘工作。从1921年到1996年的75年中,香港考古工作不断取得新的成绩。学者们对这个地区自史前时代到历史时期各个阶段的物质文化发展,已经有了比较系统的认识。在香港,青铜时代的遗址已发现90个(图一),其中近半数得到试掘或发掘,积累了丰富的资料。近10年来,香港、深圳、珠海、中     

David Hartley's psychobiological associationism and the legacy of Aristotle

The idea that there are certain "laws" of learning (similarity, contrast, contiguity) can be traced to Aristotle. He maintained that external stimuli cause small movements in the vessels to the dominant heart, the vestiges of which can be linked to one another. Aristotle's laws of learning were incorporated into the writings of Hobbes, Locke, and Berkeley, men who said nothing about the physiological correlates of mental associations. This left the door open for David Hartley to combine mental associationism with the Newtonian idea that sensations can cause minute particle vibrations in the nerves. Hartley's amalgam of psychology, philosophy, and neurology was first presented in 1746, as a "trial balloon" at the end a little-known monograph on a treatment for kidney stones. It was repeated three years later in his better-known Observations on Man. In many ways, modern psychobiological connectionism can be traced back to Hartley's Conjectures of 1746, in which Aristotle's original thoughts were modified with then current ideas about functions of the mind and the nervous system.     

战国古币的铅同位素比值研究——兼说同时期广东岭南之铅

一、引言中国所产铜、铅、锡等用于青铜生产的金属矿产原料,因各地地质条件不同,在品种和质量方面常有不同。在古代冶铸技术的历史条件下,这种差异常常使各地的青铜产品带有自己的特点。如《考工记》所载:"烁金以为刃,……郑之刀、宋之斤、鲁之削、吴越之剑,迁乎其地弗能为良,地气然也。……吴越之金锡,此才之美者。"希望今后有机会对春秋时期的青铜器物进行系统的比较实验研究,以作进一步之验证。
