采用特制的Ｆｅ－Ｓｉ、Ｆｅ－Ｍｎ合金系列标样，用电子探针测定了钢或铁基合金中低含量的Ｓｉ和Ｍｎ元素，与用纯元素作标样、经ＺＡＦ修正的结果相比较，提高了分析准确度．
Using special Fe-Si, Fe-Mn alloy series of standard samples, the content of Si and Mn in steel or iron-base alloy with low content of Si and Mn was measured by electron probe, compared with the result of ZAF corrected by pure element , Improve the analysis accuracy.
