secant line

基本解释

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。
A new damping estimation method, the secant line method, was presented, that is based on the distance of neighbor peaks and valley of oscillation.
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。
Especially, as com-pared with the 0.618 method and the parabolic function-fitting method, the double-secant line method makes the efficiency of the unidimensional search raise obviously.
特别是双割线法与0.618法和抛物线插值法相比。可使一维搜索的效率明显提高。
