烽火台是我国古代防御工程体系的组成部分,也是我国古代军事通信的重要手段。我国烽火台的出现早于长城,在军事要地以及交通不便、人烟稀少的边疆地区有众多的烽火台。烽火台汉代称事还,唐时称烽台,明朝称烟墩、墩台,史书上林峰除。另外,还有称狼烟台和烽堆的。尽管名称不一,但其功能都是用烟或火两种方法传递军情的。作为军队耳目和联络信号的烽火台,是设五在山顶或高处,每隔一两千米用土石堆砌的台子。据《明史卷.第gi卷》记载,绵延千余里的高大边墙就有峰堆三万余处。烽火台上“广积粮草,昼夜轮流看望。遇有急警,昼则举烟,…  相似文献

In 1858 Dr. Brown-Séquard arrived in London. During his stay there, he was appointed physician at the National Hospital for the Paralysed and Epileptic (now the National Hospital), and was elected Fellow of the Royal College of Physician's of London, as well as Fellow of the Royal society. During this time he also published his 'Course of Lectures on the Physiology and Pathology of the Central Nervous System' an early exposition of what is now know as 'his' syndrome. During his time in London, Dr. Brown-Séquard made many well-known acquaintances, amongst others Charles Darwin, T.H. Huxley, and Louis Pasteur. Three years after his appointment as physician at the National Hospital, he left London. Increasingly, he was to abondon fashionable practice to concentrate on his study of what are now known as the endocrinal glands. In this way, he became a pioneer of the study of endocrinology.  相似文献

Abstract

This paper examines how CCTV-assisted bird-watching mediates people's relationship with a particular representation of an animal world. By focusing on people's interpretations and responses to CCTV camera technology at three bird-watching sites around Scotland, it is argued that the use of CCTV technology represents a qualitatively different mode of engaging with birds which has bearing on how this mediated animal world appears in and to people's everyday lives. It is asserted that the spatial relations invoked in the act of looking at birds through a CCTV lens inscribe a conceptual hyper-separation between see-er and seen that serve to normalise a vision of humanity inherently separate from and dominant over the wildlife on screen. As a technologically mediated way of seeing, the paper explores the use of CCTV cameras as inscribing particular ‘ways of being’ that serve to define and limit people's conduct towards the birds on view. By drawing attention to the conservation discourses that support, and are supported by the use of CCTV-assisted bird-watching, it is argued that the notion of ‘keeping an eye on nature’ is embedded in a cultural agenda that assists with the construction of nature as tele-visual commodity.  相似文献
