摘要 利用瞬发γ中子活化分析(PGNAA)技术的煤炭成分在线检测系统(MJA),对不同的煤炭样品进行实验测试,通过对不同重量煤样的实验谱进行分析研究,提出了容重补偿模型,利用修正函数校正了样品重量变化对测量结果的影响。经实验验证,模型切实可行,能满足生产现场要求。 The influence of the sample weight(or thickness)was investigated on the coal online measuring system(MJA)based on prompt gamma neutron activation analysis(PGNAA)technology.A series of the coal samples with different weights were tested and the experimental spectra were analyzed.An amended method was proposed to correct for the influence of the sample weight.Experimental results indicate that this method is feasible,and the measurement results can satisfy the request.
