The geometric meaning of the parameter is the mono increasing distance along the curve path.

这里三次样条函数中参数几何意义是沿曲线路径单调增长的距离。

The advantage of the proposed spline functions is easy splitting of given curves according to the curve path distance.

这种插值曲线的优点是容易按距离对插值后的曲线作任意分割。

P1 If we have a curve c, from a point p0 to a point p1 then the line integral for work depends only on the end points and not on the actual path we chose.

如果曲线c，起点为P0，终点为1，那么计算所做功的线积分，只与端点位置有关，而与我们选择的路径无关。

The included app's well-designed interface shows an animation of your putts and displays a curve indicating the path of your stroke, which can be overlaid against that of a previous, model putt you've chosen.

Global Hawk can pick out objects as small as a truck with its synthetic aperture radar, which uses the plane's flight path to simulate the curve of a radar dish several hundred meters long.
