摘要
成分的影响是核分析的主要问题。理论计算和分析表明,由Fe_2O_3含量变化所产生的误差,是双能γ射线穿透法测量煤炭灰分的主要误差。根据误差随成分及灰分变化的规律,可进行补偿,以修正Fe_2O_3和H_2O的变化对测量的影响。
The effect of constituent variations is the principal problem for nuclear analysis. Theoretical calculations and analyses show that the error caused by variation in content of Fe2O3 in the ash is the main error by dual energy r-ray transmission techniques for measuring the ash content in the coal. According to the variation of error with the constituents and ash, compensation methods can be established to correct the effect of Fe2O3 and H2O variations on practical measurement.
