连续谱效率法是一种不用同时测量标样的电子探针定量分析方法。谱仪的x线探测效率是事先由连续谱的精确测量数据得到的,并且经过少数几种稳定易得的标准样品的标定。本文阐述了这种方法的原理,并列举了一些观测结果。 The continuous spectrum efficiency method is an electron probe quantitative method that does not require simultaneous measurement of standards. The x-ray detection efficiency of the spectrometer was previously obtained from accurate measurements of the continuous spectrum and was calibrated with a few of the most readily available standard samples. This article explains the principle of this method and cites some observations.
