沿地面或靠近地面传播的表面波能量。通常以较低的速度,较低的频率和较高的振幅为特征。地滚波经常掩盖有用的反射信号。源和地震检波器模式,频率滤波,f-k滤波和叠加可用来消除它。通常是一种修改的[[Special:MyLanguage/Dictionary:Rayleigh_wave|''Rayleigh wave'']] (q.v.),地滚有时称为伪瑞利波。参见图[[Special:MyLanguage/Dictionary:Fig_R-3|R-3]]
Surface-wave energy that travels along or near the surface of the ground. It is usually characterized by relatively low velocity, low frequency, and high amplitude. Ground roll tends to mask desired reflection signals. Source and geophone patterns, frequency filtering, ''f''-''k'' filtering, and stacking are used to discriminate against it. It is usually a modified [[Special:MyLanguage/Dictionary:Rayleigh_wave|''Rayleigh wave'']] (q.v.), and ground roll is sometimes called <b>pseudo-Rayleigh waves</b>. See Figure [[Special:MyLanguage/Dictionary:Fig_R-3|R-3]].

沿地面或靠近地面传播的表面波能量。通常以较低的速度,较低的频率和较高的振幅为特征。地滚波经常掩盖有用的反射信号。源和地震检波器模式,频率滤波,f-k滤波和叠加可用来消除它。通常是一种修改的Rayleigh wave (q.v.),地滚有时称为伪瑞利波。参见图R-3
