应用引入变量卡诺图化简逻辑函数

SIMPLIFICATION OF LOGICAL FUNCTION BY ENTERING VARIABLE IN KARNAUGH MAP

引入变量卡诺图，使多变量卡诺图得以简化，为多变量逻辑函数应用卡诺图化简提供了方便.

A simplification of logic function by Karnaugh map can be very object and very easy to get the simplifing logical function. But when variable's numbers are more than five in logical function, the Karnaugh map is no practical value because it's structure is too complex to use.The entering variable in karnaugh map can simplifing more varable Karnaugh map, so it gives a convenient for simplification of logical function by Karnaugh map.
