In order to achieve the simplest sequential logic circuit in the process of obtaining JK driving equation using the next state Karnaugh map. In this paper, the characteristics of JK flip-flop are analyzed, and the problem of the traditional method of JK flip-flop drive equation is proposed, and the improved method of JK driven equation is proposed by using the next state Karnaugh map. And through the example, the process of the design of sequential logic circuit is described. The pro-posed method is feasible.%在应用次态卡诺图得到JK驱动方程时，为了达到时序逻辑电路设计最简化。论文在分析JK触发器的特性，及求取JK触发器驱动方程的传统方法中存在的问题，提出了用次态卡诺图求取JK驱动方程的改进方法。并通过示例说明利用该方法进行时序逻辑电路设计的过程。由此得出所提出的改进方法是可行的。
