用绳正法拨正曲线,在计算拨道量后需要对计划正矢、拨道量进行修正。修正方法可大致分为三类:半拨量法(中央点法)修正的设计正矢是线型,拨道量修正成为梯型;图解法是用图修正拨道量,修正的设计正矢也是线型的;电算法将曲线分成若干段,采用不同的设计正矢,以控制过大的拨道量。

Use the ropes positive method to allocate a positive curve, after calculating the amount of dialing, you need to correct the plan positive vector and dialing amount. The correction methods can be broadly divided into three categories: the half-dial method (central point method), the correction of the design positive vector is a linear type, the correction of the dial amount is a ladder type, the graphic method is a method of correcting the amount of set- Is also linear; electrical algorithm will curve is divided into several sections, using different design positive vector, in order to control the excessive amount of dial.
