track line meaning in English
架空线。
Examples
- Track line of sounding
测深航线 - Multiple - track line
多线铁路 - Double track line
双线铁路 - In this paper , the problem of calculating movement of piece is simplified to the problem of finding track line segments between vertices and edges , hence the time complexity is much reduced , and special cases such as inner cavity and inner nfp ( no fit polygon ) can also be tackled
摘要将多边形滑动碰撞问题转化为顶点和边之间的轨迹线提取问题，从而降低了时间复杂度，并可统一处理边界空腔和内部靠接临界多边形问题。 - The main principles of this new approach are : 1 ) find out the track line segments for vertices of one polygon to another polygon ' s edges ; 2 ) get the enclosing polygon and internal clockwise loops that was formed by the track line segments , finally the result polygons are the final nfps
该算法的基本原理是： 1 )求解多边形顶点相对于另一多边形的轨迹线； 2 )求解轨迹线集合所形成的外包多边形和内部顺时针环，得到的多边形即为临界多边形。
