【Abstract】 This paper is to make the first accurate measurement and investigation of bronze arrows which are of the largest in number of actual combat weapons unearthed from Qin Terracotta Warrior and Horse Figure Pits,according to the geometric parameter including size, form, surface roughness and surface quality. Based on the above the structure function manufacture technology and geometric accuracy of the bronze arrows and relative systems of product management and mechanical technology in Qin Dynasty are analyzed and discussed. Especially the statements such as the grinding technique application and the manafactured size distribution fitt to the normal distribution in the Qin Dynasty are put forwared in this paper.更多还原
