即使消费性电子商品也受到影响，例如全球定位系统必须考虑时间延滞，以修正人造卫星上时钟的速度。
Even consumer electronics is affected-the Global Positioning System must allow for time dilation, which alters the rates of clocks on its orbiting satellites.
本文利用比较方法讨论延滞系统解的整体存在性问题，得出延滞系统解的整体存在性的若干判别准则。
In this paper, we use the comparison method to discuss the global existence of solutions of a delay-differential system. Some criteria for the global existence of RFDE are given.
