熵平均法在放射性数据处理中的应用研究

Study on the Application of Entropy Average Method in Radiation Data Processing

本文阐述了消除放射性数据局部干扰的方法和必要性以及熵平均法对放射性数据局部干扰消除的基本原理和方法。通过熵平均法在某剖面数据的应用,可以看出对局部突跳点干扰处理中,熵平均法的效果要好于多点圆滑法,较好地压制了干扰而突出了异常信息,熵平均法对于γ测量随机影响的消除起到了较好的效果,使地面γ测量得到了较好的应用。

This paper briefly describes the method and necessary for local disturbance elimination,basic principle and the entropy average method for local disturbance elimination in radiation data.Through the entropy average application in the profile data,it is showed that entropy average method can suppress more local disturbance and weaken less the abnormality than multi-point smoothing method in local disturbance elimination.These results indicate that the entropy average method is effective for random influences elimination of ground γ measurement and show more prospects in other application of γ measurement
