1·A new damping estimation method, the secant line method, was presented, that is based on the distance of neighbor peaks and valley of oscillation.

摘要提出利用相邻波峰和波谷之间距离估计阻尼比的割线方法。

3·A secant is defined as line passing through two points of the curve.

割线的定义是一条通过曲线上两点的直线。

4·It indicated that, whether double-line method or single-line method, the relation curves between secant modulus and pressure for unsoaked samples and soaked samples under the sam…

割线模量差与初始含水量的关系曲线按指数形式进行拟合比较合理。
