本文介绍加速器质谱计用于测定天然物质中超微量同位素~(10)Be及其在地球科学中的应用。环绕样品~(10)Be的测定可用于研究大气和海洋中发生的各种传输作用过程;大陆沉积物~(10)Be分布及迁移直接与黄土(或土壤)的堆积和侵蚀有关。~(10)Be是一种反映各种地球化学作用过程的理想的示踪剂。
This article describes the use of accelerator mass spectrometry in the determination of trace amounts of isotopes of natural beings (10) Be and its applications in geosciences. The measurement of ~ (10) Be surrounding the sample can be used to study various transport processes occurring in the atmosphere and the ocean. The distribution and migration of ~ (10) Be in the continental sediments are directly related to the accumulation and erosion of loess (or soil). ~ (10) Be is an ideal tracer to reflect the various geochemical processes.
