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。
2
The acoustical properties and specific heat of sample at low temperatures were studied, and the temperature dependences of modulus, sound attenuation and specific heat were obtained.
对其低温的声学和比热容性质进行了研究,得到了样品模量和声衰减以及随温度变化的规律。
3
The attenuation peak and the imaginary modulus peak shift to higher temperatures when the frequency increases which are thermal relaxation phenomena.
