摘　　要：由于主从JK触发器对解决一次变化并不太理想,使用方面受到一些限制,而维持阻塞D触发器完全解决了一次变化问题。本文在维持阻塞D触发器组成电路的基础上,增加了三个基本逻辑门构成的JK触发器圃满地解决一次变化。改进后的触发器,具有保持、置0、置1、翻转四种功能,是一种很理想的电路。Because of its low efficiency in the area of first - 218 variation, master-slaveJKflip-flop＇ s usage was limited to some extent, while maintaining block D flip-flop can solve this problem perfectly well. Based on the basic circuit of maintaining block D flip-flop, the paper discusses how to solve this problem with JKtlip-flop by adding another 3 logic gates in this paper. The improved flip is an ideal circuit with the four function of presetting to 1, presetting to 0, maintaining, turning over.
