摘　　要：本文研究深海锰结核中10Be的加速器质谱法分析。提出了NaOH和EDTA分离纯化-BeO制样一加速器质谱法测量10Be的分析程序。研究结果表明，该法回收率较高，分离效果较好，按该法制备的BeO靶能较好地满足加速器质谱法对测量10Be的要求。利用该法测得北太平洋两个锰结核的生长速率分别为2．7mm／Ma和1．5mm／Ma。这些结果与其他研究者所测数据相比，非常一致。This paper describes the analytical method of 10Be in deep-sea manganese nodule samplesby accelerator mass spectrometYy. This method was successfully used in the determination of10Be concentration of two manganese nodules collected from the North Pacific. Growth rateswhich were determined by 10Be method for two manganese nodules from two stations were2. 7mm/Ma and 1. 5mm/Ma, respectively. The results are in reasonably good agreementwith those obtained in other nodules by other investigators.
