| 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触发器圆满地解决一次变化。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。

| Abstract: | 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 JKflip-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. |
