In this paper, a region approximation idea that means using a "fat curve" with a width to approximate the offset curve is proposed, and a complete set of algorithms to approximate offset curve using disk Bézier curve are given and implemented. In the algorithms, the optimal and uniform approximate curve of the offset curve as the central curve of the Disk Bézier curve is found by using Remez method, and then the upper optimal and uniform approximation principle is proposed to compute the error radius function of the Disk Bézier curve. Thus, the whole Disk Bézier curve can be obtained. In the end of this paper, the approximate effect of the Disk Bézier curve is not only analyzed and assessed, but also some specific examples are provided.

space curve：空间曲线

相贯线是相交两立体表面的共有线,一般是封闭的空间曲线(space curve),特殊情况下也可能是平面曲线(plane Curve)或直线(straight line). 因相贯线是两立体表面共有线,所以求相贯线的实质是求两立体表面共有点的投影. 先求特殊点,
