摘　　要：用加速器质谱测定１０Ｂｅ同位素，研究深海沉积物和多金属结核中１０Ｂｅ同位素的含量分布，获得相关的地质年代、沉积速率和生长速率。A method for determination of 10 Be isotope by accelerator_mass spectrometry was developed. Concentration and distribution of 10 Be in deep sea sediments and polymetallic nodules were studied. More useful information about deposition rates of deep sea sediments and growth rates of polymetallic nodules were obtained from the study.
