time-scale

基本解释

But there can be no general rules, nor standard time-scale.
但是不可能存在普适的规则，也不存在标准的时间表。
Then, through solving the slow time-scale problem by optimal control theory, the optimal reduced-order reference trajectory is obtained.
然后，应用最优控制理论得出慢时间尺度上的解，并将其作为降维后的最优参考轨迹；
Furthermore, the tracking law in the fast time-scale model is designed using the feedback linearization methodology from nonlinear geometric control theory.
在此基础上，利用非线性微分几何反馈线性化方法，设计快时间尺度制导指令，实现对参考轨迹的跟踪。

"For the very first time, a large-scale solar power plant, the largest of its kind in the entire nation, will deliver electricity produced by the sun to the citizens of the Sunshine State.

When Greek and Italian debt yields started to spike we witnessed the rare event of a human-time-scale criticality.

Combine this with a short time-scale—ideally agile proponents seek to deliver a working bit of software every few weeks—and you have an accelerated, informal version of the iterative model.
ECONOMIST: The software-development industry
In this tight, discreet narrative, which drifts from one memory to another as if love had its own time-scale, the author movingly describes how Jim freed the narrator from the phantoms of her past and the righteousness of her family and friends.
