1) water-retardation frequency
水滞频率
1.
the water-retardation frequency portion, and within this portion the measured compactness response value has almost no connection with the moisture content in soil.
即在瞬态冲击下,存在S-G低频水滞频率,其压实度响应值与它的含水量几乎无关,并用均方谱作为指标,具有较高的响应值分辨力。
2) frequency hysteresis
频率滞后
3) frequency hysteresis
频率滞后，频滞
4) frequency hysteresis
频率滞后;频滞
5) water-retardation frequency portion
水滞频段
1.
By using water-retardation frequency portion,influence of water content on impact response value was avoided and compactness of coarse grained soil was measured without considering water content.
通过水滞频段的应用,消除了含水量对响应值的影响,可以在不检测含水量的情况下测定中粗粒土的压实度,在此基础上确定了动态冲击响应值与中粗粒土的压实度关系。
6) specific retention
滞水率，保水率
