当曲线状态不算十分紊乱,特别是缓和曲线正矢状态较好时,现场往往采用简易计算法计算拨道量。采用本文建议的步骤,可使计算得到进一步简化。算出正矢逆差(设计正矢—实测正矢)后,第一次先不考虑编号为偶数的点,而只将奇号点的正矢拨到设计状态,拨动量等于该点的正矢逆差。第二次则不考虑奇号点,而只将偶号点的正矢拨到设计状态,显然,其拨动量等于该点的正矢逆差加上其前、后点第一次拨动量之和的一半。由于第二次拨动,使得已经拨到设计状态的奇号点的正矢又发生了变化,为恢 When the curve state is not very disorder, especially when the positive curve of the relaxation curve is good, the field calculation method is often used to calculate the amount of dialing. Using the steps suggested in this article, the calculations can be further simplified. Calculate the positive vector of the deficit (design positive vector - measured positive vector), the first time without considering the number of even-numbered points, and only the positive point of odd-numbered points allocated to the design state, the dial is equal to the amount of positive vector Deficit. The second does not consider odd-numbered points, and only the positive of the even-numbered points allocated to the design state, apparently, its call-out amount is equal to the point of positive-deficit plus its before and after the first call to move Half of the sum. Due to the second toggle, the positive vector of odd-numbered points that have been allocated to the design state has changed again
