摘　　要：图形化简法是逻辑函数化简的有效工具。bj图和dj图分别是RM展开式、CRM展开式的图形表示。通过对RM展开式、CRM展开式系数关系的分析,提出了2种bj图和dj图的图形转换方法,并对各种方法予以实例说明。对于5变量以下的逻辑函数,这二种方法具有简单、直观等特点。Mapping methods have significant application in the simplification of logic function. The RM expansion, CRM expansion and their relative maps-bjmap and dj-map-are introduced. By analyzing the features of relations between the RM expansion and CRM expansion, new graphic methods of transform between bj-map and dj-map are proposed. Then some practical examples using these graphic methods are given. It is shown that the methods have many advantages, such as simplicity, intuition and so on.
