本文根据卡诺图的对称性,提出了简化逻辑函数的对称原则来代替过去所遵循的相邻原则,从而扩大了卡诺图法的应用范围,使之由一般只用于四变量以下逻辑函数的简化而能用于任何多变量逻辑函数的简化,这就大大减少了对于复杂的液压回路逻辑设计的困难。

According to the Karnaugh map symmetry, this paper proposes a symmetrical principle to simplify the logic function to replace the adjacent principle which was followed in the past, thus expanding the application scope of the Karnaugh map method, which is generally applied to the following four logic functions Simplification can be used for the simplification of any multivariate logic function, which greatly reduces the difficulty of designing a complex hydraulic circuit logic.
