说明：  此程序是根据《微型计算机控制技术》(第二版)清华大学出版社 第三章数字控制技术——3.2插补原理中的3.2.1逐点比较法的直线插补，3.2.2逐点比较法圆弧插补编写的。其中的变量定义，原理依据均来源于此，如有疑问，请参考书中的讲解。尤其是例子，以下两个程序的第一个运行图均与例题中的一致。
(This procedure is based on " micro-computer control technology" (second edition), Tsinghua University Press, Chapter III digital control technology- 3.2 Interpolation Principle 3.2.1 by-point comparison method of linear interpolation 3.2.2 point by point comparison France circular interpolation written. One of the variable definitions, are the principle basis from this, if in doubt, please explain the reference. Example, the following two procedures to run the diagram are consistent with examples.)
