The secant modulus is linear with axial stress. 而其割线(SEC)模量与轴向应力则呈线性关系;
The pulse envelope we obtained is a hyperbolic secant function of time. 所得脉冲包络为时间的双曲正割函数。
So the secant modulus from zero stress can not describe the deformation property of the practical rock mass. 因此,从原点计算的割线(SEC)模量不能反映实际岩体的变形特征。
By means of the theory elastic wave, this paper demonstrates direct field's being offset under fluid-fluid matrix by secant integral in well. 本文利用弹性波理论对流体&流体模型下直接场被井内流体割线(SEC)积分抵消进行了证明。
A secant is defined as line passing through two points of the curve. 割线(SEC)的定义是一条通过曲线上两点的直线。
