| 摘 要： | 逐点比较法是一种最常用的直线插补算法，而在其插补过程中，最关键的问题就是偏差值的计算．鉴于以往教材中所提供的偏差公式都存在着很大的局限性，本文经过重新推导，得出了新的具有一般性的偏差计界公式，又经实例验算，证明该算式是完全正确的．从而为正确解释绘图机直线插补过程提供了数学基础．

| Abstract: | Point-to-point method is one of algorithms that are widely used in a line inteoplation, and the deviation calculation involved in thes method holds an important position in the course of interpolation. In view of the faCt that the old formula has a rather limitation in use, a new and general deviation calculation formula for a line interpolation is put forward by reasoning in this paper, after that, the author gives an exampl e to test and verify the formula and reaches a few significant conclusions on it. |
