术语“平板仪”的详细信息

英译术语:

plane table

汉语语境:

长沙马王堆三号汉墓于 1973年12月进行了考古发掘工作，第一次发现了三幅绘在帛上的地图。第一幅属于地形图，第二幅为驻军图，第三幅是城邑图。这一重要发现引起了国内外地图、历史地理学者的极大关注。这不仅是我国已发现的最早的地图，而且在这些地图上真实地反映了当时的政治、军事、测绘技术的情况。经过不少学者考究，《九章算术》、《周髀算经》所述直角三角形计算与按比例绘制地图之法，是古地图测绘的数学基础。而测绘工具包括方向器“司南”、工具“规”、“矩”等。武汉大学王克陵教授结合历史文献中的有关记载，对“规仪”的结构和使用方法进行了推测，认为它就是早期的平板仪。

英语语境:

An archaeological excavation was done on the No.3 Han Tomb at Mawangdui, Changsha in December 1973. Three silk maps, topographical map, garrison map and city map, were respectively discovered for the first time. Meanwhile, this important discovery attracted great attentions of map scholars and historical geographers at home and abroad, since the three maps were not only the earliest ones ever discovered in our country but also the true reflection of politics, military, surveying and mapping technology at that time. After careful research, quite a few scholars thought that the methods of right triangle calculation and scaling a map described in Arithmetic in Nine Sections and Zhoubi Mathematical Guide were the mathematical basis of ancient map surveying and mapping. Surveying and mapping tools included the direction-indicating instrument Sinan as well as instruments, like “gui”, “ju”(bevel gauge), etc. Through relevant records in historical documents and a discussion of the structure and method of use of “gui”, Wang Keling, a professor of Wuhan University, infers that it is no other than the ancient plane table.
