引脚围绕网格交叉点成矩形，在引脚图层通过最小金属宽度的一半指向所有四边。
缩短型和伸长型的算法思想可以概括为求编程轨迹在加工侧等距线的交点。
他是你感知世界里无可取代的全部，但他也是你未知世界里永无交集的一点。
前方交会解算像点坐标，一个很好的程序，希望大家喜欢！
1·Intersection point closure is one of the difficulties in the processing.
交点闭合是本次处理的难点之一。
2·Special consideration is paid on the compatibility of free surface and body surface conditions at the intersection point.
对于自由面和摇板交点处自由面条件和物面条件的相容性作了专门的考虑。
3·Throught the 3-D compensation spatial correction for 2-d migrated stacking section, the 3-D compensation method makes two migrated stacking section closed in the intersection point.
三维补偿法是通过对二维叠偏剖面的三维补偿空间校正，使两条叠偏剖面在交点闭合。
4·Translate the intersection point B(0, b) to the origin. (M1)
平移交点B（0，b ）到坐标原点，写出平移矩阵M1。
1·Exposure latitude: its lower limit is at the intersection point of the two curves, with an exposure time of 15 units for the example below.
地理纬度：其下限暴露在交叉点的两曲线，与一个曝光时间15个单位为下面的例子。
