摘　　要：阐述了自然伽马能谱峰源的原因及其校正方法,并以岩芯样品的测量为例,具体介绍自然伽马能谱峰源校正的应用。实验证明,这种峰源校正的方法,提高了能谱分析的精度。The peak shift is an important reason for mistakes which are made in radioactive el- ement analysis. The GAMMA energy spectral device is used to measure natural GAM- MA energy spectrum. The paper provides the reason for the peak shift on the natural GAMMA energy spectrum and a method for correction. Moreover, the measurement of the standard rock core example describes in detail the application of correction for the peak shift on natural GAMMA energy spectrum. The method for correction is of signifi- cance in raising the accuracy in energy spectral analysis.
