- The natural logarithm of this ratio is called the logarithmic decrement. 此比率自然对数称为对数的减量。
- However, when the MR dampers are not voltage strengthened, the measured logarithmic decrement is smaller than 0.03. 而当MR阻尼器无电压输入时对数衰减率值小于0.;03，无法满足拉索减振要求。
- The logarithmic decrement of the cable is then calculated from the free decay curve of the displacement data. 通过人工激振拉索后，测得拉索的振动波腹点位移衰减时程曲线，计算得拉索的对数衰减率值。
- The Logarithmic Decrement method was employed for the damping calculation.Frictional damping at the supports of the board/retainer system was determined as well. 至于系统阻尼则以对数递减法求取，而支撑部份所引发之摩擦阻尼也加以计算。
- The studies show that compared with the conventional logarithmic decrement method, this method need not to determine the baseline, and is insensitive to baseline drift and low frequency interference. 研究表明，与传统的对数衰减法相比，新方法无须确定基线，估计结果对基线漂移和低频干扰不敏感。
- Appling conception of modal separation the first two order modes of the rotor-bearing system were obtained by research the free vibration displacement response for getting the logarithmic decrement. 运用模态分离的概念，通过求自由振动位移响应的对数衰减率而得到转子轴承系统的最低一、二阶模态的模态阻尼，亦称系统阻尼。
