什么是共同的切线斜率？
在曲面数字化方面，提出基于曲面曲率和被测点切线斜率的自适应采样规划。
During digitizing, the adaptive sampling planning method based on the curvature of surface and the slope of tangent line of measured point is proposed.
一个给定点的导数不过就是一条切线的斜率轻吻了那个点。
A derivative at a given point is just the slope of the tangent line that kisses that point.
我们知道fx和fy是,曲面上两条切线的斜率。
We know that f sub x and f sub y are the slopes of two tangent lines to this plane, two tangent lines to the graph.
