区间速度【overall speed】指的是车辆驶过某一区间,全行程内单位时间运行 ( 包括停车时间 ) 的距离。
即使我们的测值表明在不同区间速度相同,也许只能说只是在测值取得时所用的精度的条件下,这一运动才是匀速的。
Even if our measurements show the same velocity over different sections, it may be asserted that the motion is uniform only with the deGREe of accuracy that the measurements were made with.
当两个变量的比值互相影响时,如有了一个确定的速度,它可被理解为当分母在其区间内变化时分子也相应地变化。
When the ratio of two changes is involved, as it is in determining a velocity, it is understood that the change in the numerator "takes place during" the interval of the denominator.
为进一步改善控制品质,提出了区间轨迹方法,通过调整轨迹参数可以在响应速度与模型准确性之间进行选择与平衡。
To further improve control performance, zone trajectory method was proposed and a parameter was provided to trade off the response performance and model accuracy.
