在不同饱和度下测试了纵、横波速和衰减Ｑ值，发现了它们随饱和度变化的不同规律．对实验结果进行了理论分析和计算，提出了相应的影响机理，给出了很好的拟合曲线． The longitudinal and transverse wave velocities and the attenuation Q values ​​were tested under different saturations, and the different rules of their changes with the saturation were found. The experimental results are analyzed and calculated theoretically, and the corresponding influence mechanism is proposed, and a good fitting curve is given.
