The car real driving cycle usually is a velocity-time curve based on times.
乘用车实际行驶工况通常可表示为基于时间的一段时间-速度曲线。
If you were thinking of a velocity field, that would measure how much fluid is passing through the curve in unit time.
想象一个速度场，它能够度量，单位时间内流体的量。
The curve of evapotranspiration is the typical unimodal sort, but for the difference with the amplitude , velocity , the size and time of the maximum evapotranspiration.
不同天气情况下，作物蒸发蒸腾量的日变化曲线基本相同，都是典型单峰型，变化的幅度、变化速率、峰值出现的时刻以及峰值的大小有差异。
In this paper, it studies the algorithm of S-curve with a constant velocity duration in detail, which takes time optimal into account. A simulate example is taken to test each switching point.
文中着重对S曲线加减速算法进行了深入的研究，推导出以时间最优为目标、具有恒定速度段的S曲线加减速的计算公式，并通过仿真进行验证，得出加速度曲线的各个时间转折点。
