均匀三次B样条曲线插值，给定若干点求出曲线(Uniform three times B spline curve interpolation, given a number of points to find the curve)

通过四重节点办法算出控制点坐标，根据控制点拟合通过型值点的3次B样条曲线(The coordinate of control points is calculated by four nodes method, and the 3 B spline curve of the control point is fitted through the value point of the type)
