基于光顺曲线设计需求，一条曲率单调且曲率正负不变的三次平面H-Bézier螺线段被构造。由于此螺线具有起点曲率为零的特性，它可以替代回旋曲线作为道路设计中的缓和曲线。同时螺线还含有形状参数，故它具有曲线形状可调性的优点。最后，利用此H-Bézier螺线，构造了两直线间满足G2连续的缓和曲线。

Based on the requirement of fairing curves design, a planar cubic H-Bézier spiral with monotone curvature of constant sign is discussed. Since this spiral segment has zero curvature at the beginning point, it is suitable for applications such as highway design where the clothoid has been traditionally used. And since the spiral also contains a shape parameter, it has the advantage of adjustable curve shape. Finally, G2 continuous transition curves between the two lines are constructed by the use of the H-Bézier spirals.
