摘　　要：讨论了基于dj图和降维dj图计算逻辑函数的一阶布尔偏导数和二阶布尔偏导数的图形方法.实例表明该方法具有直观、简单等特点,并且它能给出布尔偏导数的最简CRM式.The methods of calculating Boolean partial derivative of a logic function are discussed. The graphic methods of calculating first-order, second-order partial derivative by using dj-map and reduced-dimension dj-map are proposed. The minimized OR-Ceincidence expression of Boolean partial derivative can be gained directly from dj-map and reduced dimension dj-map by using these methods. The examples show that the methods have the features of intuition, simplicity, easy mastery and so on. The discussion is helpful to expand the application area for dj map and perfect the research on OR-Coincidence algebra system.
