本文利用top-down技术中的控制图法进行原子荧光法测定土壤中砷的不确定度评定。top-down技术应用基础为实验室必须具备一个良好的内部质量控制体系。
In this paper, the uncertainty of arsenic in soil was determined by atomic fluorescence spectrometry using the control chart method of top-down technique. top-down technology is based on the laboratory must have a good internal quality control system.
