众所周知高合金钢的X射线荧光光谱分析的准确度,在很大程度上取决于基体影响的校正,而大分析范围的基体校准方法虽然很多,但是各有其优缺点。De Jongh模式的优点,可以采用理论校正系数,因此只要少量标准钢样做校准曲线,这类系数的优点在各文献中已有报道,理论《系数是专为某一定成份而计算出来,所以仅对某一成份范围分析有效,对比较大范围的分析时,必须把它分成:条校准曲线,以达到更好分析准确度,例如分析高合金钢(Ni 0—40%) (Cr 6—25%)(Mo 0—5%) (Nb 0—3%)(W 0—6%),Ni的校准曲线可以分成Ni(0—25%)和Ni(25—40%)二条。
It is well-known that the accuracy of X-ray fluorescence spectrometry of high-alloy steel largely depends on the correction of substrate influence, while the matrix calibration method of large analysis range has many advantages but each has its own advantages and disadvantages. The advantages of the De Jongh mode are that the theoretical correction factor can be used. Therefore, as long as a small amount of standard steel is used as the calibration curve, the advantages of such coefficients have been reported in various literatures. The theoretical "coefficient is calculated for a given component and therefore only When analyzing a range of components, when comparing a wide range of analyzes, it must be divided into: a calibration curve to achieve a better analysis of the accuracy of the analysis, for example, high alloyed steel (Ni 0-40%) (Cr 6-25 (Mo 0-5%) (Nb 0-3%) (W 0-6%). The Ni calibration curve can be divided into Ni (0-25%) and Ni (25-40%).
