摘　　要：介绍了一种应用于脉冲快热中子分析技术中的新解谱方法。此方法采用 9 道计数的和去寻找元素特征γ峰的峰位,利用相对误差的最小值确定特征γ峰的左右边界。利用此方法,已经使测量精度达到了煤质分析的要求,并且研制出脉冲中子煤质快速分析仪。A new method of data processing used in pulse fast thermal neutron analysis technology is introduced. In this method, the sum of the counts of nine channels was used to search the position of the characteristic gamma-ray peak of the specific element to confirm the boundaries of the γ peak with the least relative error. By using this method, the measurement precision has reached the requirement of coal analysis, and a pulse neutron coal fast analyzer has been developed.

关 键 词：特征峰峰位 特征峰的面积 相对误差
