铁质南唐永通泉货和南北宋铁币的正电子湮灭与其它测量分析

RESEARCHES ON SOUTHERN TANG IRON“YONG TONG QUAN HUO”COINS AND SOME SONG IRON COINS USING PAT AND OTHER TECHNIQUES

采用正电子湮灭技术和金相显微以及扫描电镜能谱技术对南唐永通泉货铁钱和若干南北宋铁钱进行了研究。结果表明，早在南唐时期，我国铁币冶铸技术已达到一定水平，且在宋代有所改进。测试表明，正电子湮灭技术结合其它测试方法。

PAT and other techniques have been used to study the composition micro structure and defects of the iron coins minted in the Southern Tang Dynasty and the Northern and Southern Song Dynasties.The results show that the iron coin mint technique had reached a fairly high level as early as the Southern Tang Dynasty and that some improvements were made during the Northern and Southern Song Dynasties.They also show that PAT can be used to study ancient iron coins and make an appraisal of them.
