说明：  PCB上的任何一条走线在通过高频信号的情况下都会对该信号造成时延时，蛇形走线的主要作用是补偿“同一组相关”信号线中延时较小的部分，这些部分通常是没有或比其它信号少通过另外的逻辑处理；
(PCB on the alignment of the adoption of any one case of high-frequency signal will cause the signal when the delay, snake-like alignment of the main role is to compensate for " the same group of related" signal line delay smaller pieces, these parts are usually yes or no less than other signals through a separate logical treatment )
