摘　　要：本文主要介绍了用^（２１０）Ｐｂ─^（２１０）Ｂｉ法测定海洋现代沉积速率和数据处理方法的研究。该方法测定的结果与^（２１０）Ｐｂ─^（２１０）Ｐｏ法和阴离子交换－ＥＤＴＡ纯化－硫酸钡镭沉淀－α计数法（简称^（２２６）Ｒａ法）以及厦门大学海洋系经研究改进的分离、纯化^（２１０）Ｐｂ的离子交换法的测定结果相当吻合。The marine recent sedimentation rates introduce mainly the studies of determined by the￣(210)Pb─￣(210)Bi method and the studies of the radiation determination and data are introduced mainly.The results are in good agreement with that obtained by the￣(210)Pb─￣(210)Po method,the method of anion-exchange─EDTA purification radium barium sulphate preciptation─αcounting (called￣(226)Ra method)and by the method of the developed ion exchange by Xiamen University through the separation and purification of￣(210)Pb.
