土壤侵蚀示踪稀土元素的中子活化分析技术
- Title:
- INAA of Tracing REE Applied to Studies of Soil Erosion
- Keywords:
- soil erosion; REE tracer method; INAA
- 摘要:
- 介绍了应用REE示踪法研究土壤侵蚀的中子活化分析方法。试验结果表明，与REE示踪法相结合的中子活化分析技术，用以定量地测定各种不同地形部位的相对侵蚀量，具有较高的精确度及灵敏度，其相对误差均小于15%。室内外试验分析结果证明了该方法为土壤侵蚀的量化研究提供可靠的分析手段。
- Abstract:
- INAA techniques of tracing REE applied to studies of soil erosion has been introduced in this paper. Experimental results have showed that this method can be used for precise determination of soil erosion arnounts on different topographical parts with a relative error less than 15% while it be used with the REE tracer method together. It also provide a reliabIe way for quantitative study of soil erosion.
