7Be在灰色黄土正常新成土土壤颗粒中的分布

摘要

[Objective] The research aimed to study the absorption ability of 7Be in different grade soil particles. [Method] The mechanical composition of the soil sample was analyzed and 7Be distribution in different grade soil particles of Loess Plateau was determined. [Result] There was different 7Be amount in different grade soil particle. [Conclusion] The regular of 7Be amount in soil was clay > silt >sand.%[目的]为了分析不同粒级土壤吸附7Be的能力.[方法]通过对土壤样品的机械组成分析,分析不同粒级土壤颗粒中7Be的分布.[结果]不同粒级土壤颗粒中7Be的分布不同.[结论]7Be含量在不同粒级土壤中的分布规律为黏粒＞粉砂粒＞砂粒.
