摘　　要：地面伽马能谱测量是一种常见的地质勘探方法,其在现代地质勘探工作中有广泛的应用,但在实际测量中,其测量值会受到外界随机干扰的因素的影响。通过熵平均滤波处理,可以对测量中的随机干扰起到一定的压制作用。Ground gamma spectroscopy is a common geological exploration method,which has been widely used in modern geological exploration work.However,in actual measurement,its measured value will be affected by factors of random interference from the outside.Through the entropy averaging filtering process,it can suppress the random interference in the measurement.

关 键 词：地面伽马能谱测量 随机干扰 熵平均法
