tangent length

基本解释

This paper presents two kinds of new methods for setting out circular curve: free angle and tangent length method.
介绍了测设和检验圆曲线的两种新方法：任意角夹角法和任意切线长支距法。
Crack length estimated by unloading tangent and secant compliances are approximately equal to the traction-free segment of crack and the measured crack length respectively.
分析表明，根据卸载切线柔度估计的裂纹长度近似地等于裂纹的无表面力段长度，根据割线柔度估计的裂纹长度等于测量的裂纹长度；
At any knots, the nearly arc length are precise for the resulting nearly arc length parametric curve, and it has the unit tangent same as that of the real arc length parametric curve.
所作近似弧长参数化曲线在插值节点处，近似弧长是精确的，并且具有与精确弧长参数曲线同方向的单位切矢。
