The viscosity coefficient of pore fluid in saturated sandstone has an obvious effect on the attenuation, modulus, and velocity dispersion in low frequency range.
饱和砂岩中扎隙液体的粘滞系数对饱和砂岩的衰减、模量和速度色散的影响在较低频段是明显的。

In low field range, the change of current with time can be simulated by attenuation of power index, and the attenuation coefficient intends to decline with the increase of the applied electric field.
