1
那我一定穿越时空的阻隔，划条公垂线向你冲来，一刻也不愿逗留。
Then I must through the barriers of time, draw a male vertical to you came on at a moment, also not the wish to linger.
2
两条异面直线的距离也不必要找出公垂线段，只需利用向量的射影性质来解即可。
Two different surface straight lines distance not essential discovers male hangs the line segment, only must solve using the vector projective property then.
3
该方法利用空间两异面光轴公垂线估计交会点位置，克服了常规算法中的模型误差。
The method estimates intersecting point by means of optical axis public vertical line of two different planes in space.

公垂线
一条直线同时垂直于两条或两条以上线段或直线，这条直线就是被垂直的线段或直线的公垂线。然而，如同两条异面直线的公垂线夹在异面直线间的部分，这才被叫做公垂线段。
