摘要：

Precise experimental results, combined with theoretical predictions, indicate that seismic energy loss caused by grain boundary friction is important only at low confining pressure and at strains greater than about 10-6. Since these conditions are generally not encountered in seismology, frictional attenuation is not importantin situ. Other mechanisms such as fluid flow must dominate seismic attenuation in the upper crust. © 1979 Nature Publishing Group.
