摘　　要：从二个独立的直角坐标系出发 ,分析中插缓和曲线点位坐标计算的完整模式 ,说明中插缓和曲线有别于一般缓和曲线的两种基本关系 ,指出有效选用连接参数m值在准确计算中插缓和曲线完整点位坐标避免曲线断链的重要作用 。In accordance with two independent rectangular coordinate systems, this paper discusses the complete coordinate formula of the middle spiral curve, the two groups' basic relation which is different to the general one and the significant intentions for averting chain breaking, which comes from the line parameter selected to compute the right coordinate of the curve points. And thus, it explains the coordinate transformation technology and its effects with free measurement stations for middle spiral curve.
