The data that defines an SVG path element consists of a series of coordinate values defining points, and additional control characters preceding a point.

定义 SVG 路径元素的数据由一系列定义点的坐标值及在点之前的附加控制字符组成。

To do this, the monotone curve is firstly drawn, and then without finding the coordinate of the inflexion point, the NC machining path can be obtained by the method of automatic direction control.

Secondly, the meshing path of the contact point of SCMW is deduced based on the meshing function of space curve and the space coordinate transformation.

其次，本文在前期研究建立的空间曲线啮合方程基础上，结合空间坐标变换，推导出空间曲线啮合轮的啮合轨迹；

In discussion several times this morning with Secretary Tom Ridge, the effort is heavily under way to coordinate an understanding of exactly where the orbiter path had taken it from West Texas toward the Kennedy Space Center here in Florida, and to make sure that the material on the ground is secured so that the investigation can begin promptly.

However, overall success of interventions in changing the long-term path of a currency is less certain--and they only seem to work when nations coordinate their efforts--highly unlikely in this environment.
