There's a time lag between infection with HIV and developing AIDS.
从感染艾滋病病毒到发展成为艾滋病病人有一定的时间间隔。
He cautions, "There always is a reputational lag. It will take some time before improvement is noticed, and even more time before people actively seek you out for the important work."
他强调，“总会有一个名誉恢复的间隔，所有的进步在被注意前总要有些时间，如果要人们重新认识你来提供你重要的工作则需要更多的时间。”
The interval of the time lag is identical of each lane controlled and when the input is a random sign, we can adopt quadratic function of optimum control and separation theorem.
当受控对象各控制通路中滞后时间间隔都相同，且输入为随机信号时，可采用二次函数型最优控制定律和分离定理。
