摘　　要：研究了煤中铁含量变化对煤灰分测量的影响和铁补偿方法测量煤灰分的基本原理。推导了铁补偿方法测灰的数学方程和多元函数常系数的回归拟合方法。借助于平衡滤光片的闪烁探测器建立了一套测灰装置。The effect o0f varying iron concentration on measuring the ash content of the coal and the basictheory of the measuring by compensation for variation in iron concentration in the ash is discussed,The mathematical formula of the measuring has been derived and the regression analysis methed hasbeen established for constants of multivariables function. A measuring device has been complected bymeans of the scintillation detector with balanced filters.Experiment results are discussed.
