摘　　要：分析了逻辑函数的OC展开式与RM展开式,利用异或运算和符合运算的性质,推导了dj展开系数与bj展开系数的关系.在此基础上提出了基于折叠异或以及基于重心的实现dj图和bj图相互转换的两种图形方法,并对这两种方法作了比较.通过实例显示,这些图形方法具有直观、有效等特点.The OR-Coincidence（OC） expansion and the RM expansion of logical function are analyzed and then the relationship between the dj expansion coefficients and the bj expansion coefficients is deduced by the use of the properties of Exclusive-OR（XOR） and OC operations. Based on it, two graphic transformation methods between dj map and bj map based on the folding XOR and the center of gravity, respectively, are proposed and compared. Their advantages such as intuition, effectiveness and so on are shown by the use of examples.
