中子活化分析在当代无机痕量分析计量学中的作用  Ⅱ.参量法NAA——相对法NAA的理想辅助方法

Role of Neutron Activation Analysis in Metrology of Modern Inorganic Trace Analysis Ⅱ.Parametric NAA——an Ideal "Back-up" Method for Relative NAA

摘要: 简单介绍了k0 NAA原理,分析了k0 NAA结果的溯源性和不确定度,及其作为相对法NAA辅助方法的可贵特性。指出k0 NAA的同时使用进一步加强了相对法NAA的比较基准法地位。

Abstract: The principle of k_0-NAA is briefly introduced. The traceability and uncertainty of k_0-NAA results are analyzed. The valuable characteristics of k_0-NAA as a "back-up" of relative NAA are described. The concurrent use of k_0-NAA will greatly strengthen the position of relative NAA as a primary ratio method.
