ACP 1 (AcousticConcentration Profiler) has been success fully applied to sediment observations in West lake .
声学泥沙浓度剖面测绘仪在杭州西湖淤泥探测中得到成功应用。

With the concentration of the polymer solution increasing, acoustic velocity of the polymer solution decreases, and the polymer density decreases too, but the apparent viscosity increases.
随着聚合物溶液浓度的增加，其声传播速度减小，其密度值也逐渐减小，但其表观粘度值逐渐增大。

At present, electric resistance, chloride ion concentration anomaly, chloride ion profile and acoustic impedance logging data can be used to predict the gas hydrate saturation.
