摘要
研究建立了电荷积分基线补偿法 ,并应用于谱仪放大器中 ,有效地补偿了峰位随计数率的漂移。在X射线荧光分析应用中 ,当谱仪通过的计数率为 2 0 0 0～ 12 0 0 0s 1时 ,银峰的漂移降低到0
A charge integration baseline compensation method has been established and applied to the design of the spectroscopy amplifier, and the peak drifts of spectrums due to the change of count rates are efficiently decreased. In the application of X fluorescence analysis, the drifts of the peak of silver are reduced to the range less than 0.1 % while the throughput rates of the system are increased from 2 000 s -1 to 12 000 s -1 .
