摘要:

This paper describes two case studies involving an optical emission spectrometer used for measuring the chemical composition of steel. The first case study describes the design and analysis of an experiment for estimating some key components of variance in spectrometer measurements. The results of this experiment motivated several subsequent investigations, including the second case study: an investigation into causes of instability of the spectrometer.
