【摘要】 在介绍铅同位素考古优越性的基础上，进一步将数理统计方法应用到古滇铜鼓的铅同位素考古中．讨论了铜鼓和矿料据同位素比值的概率分布，并对万家坝型铜鼓及其矿料来源，云南万家坝型、石寨山型和广西麻江型铜鼓的铅同位素比值进行了分布检验，得到了一些有价值的结论．研究表明数理统计在铅同位素考古中的应用，能够解决测试数据分散性、相同性（相近性）和交叉性的问题，可以揭示出科技考古数据没有直接表示出的某些潜信息，从而得到科学的结论．因此具有广阔的应用前景．更多还原

【Abstract】 On the basis of discussing advantage of the archeology with lead-isotopes analysis, the mathematical statistics is used to the ancient-Yunnan bronze drums archeology with lead-isotopes analydsis. The probability distribution of the ratio of lead-isotopes of bronze drums and mine material is researched.The test of distribution of ration of lead-isotopes of Wanjiaba, Shizhaishan and Majiang bronze drums is performed, and some valuable conclusions are obtained.更多还原
