北京地区出土磬折“匽”刀的理化测试研究

The Analysis and Researches on "Qingzhe Yan" Coins Excavated in Beijing

本文用现代实验手段分析了北京地区出土的27枚磬折“匽”刀和4枚尖首刀。通过对检测结果和有关文献的研究,指出:先秦燕国磬折“匽”刀基本上是以铅为主的铅铜(Pb-Cu)二元合金,并对磬折刀中的少量锡和战国时期燕国大量用铅铸币的原因作了初步的探讨。

This article gives an analysis on the result of the researches on the 27'Qingzhe Yan' coins and 4 'Jian Shon' coins excavated in Beijing by meansof modern experimental measures. Testing results and the study of historicaldocuments indicate that they were ancient Chinese coins before the QinDynasty (221-207 B. C.), and that the 'Qingzhe Yan' coin is essentially analloy of lead with copper containing mainly lead. The causes of the lowercontent of tin and high content of lead in these ancient coins are alsodiscussed.
