对于各种环境演化过程和环境演化事件，只有将其置于时间标尺之上才有确切的意义，也才能从中找出规律性的东西。
Only on the time scale will various processes and affairs of environmental evolvement have their own exact meanings, which can bring us some laws at present.
你可以使用PageUp和PageDown键来以帧为单位移动时间标尺，另外，如果想要更快移动，加按Shift。
Also to refine that you can use the Page Up and Page Down keys to move frame by frame within the timeline, and adding shift to the mix moves you 10 frames either way.
之所以有这样矛盾的观点，这是因为“标尺”和“时钟”——它们标志着事件所在的时间和空间，它们对于不同的观察者来说是不一样的。
These contradictory versions arise because rulers and clocks—the things that mark time and space—are not the same for different observers.
这些原则还能帮你实现行动平衡，它们可以作为标尺帮你决定行为是否失衡，你是否把太多的精力和时间投入到了某一个方面。
They also help you achieve balance in your actions, acting as a gauge to determine when you're lopsided and have been spending too much time and energy in one area.
时间轴顶端的标尺会指出时间，单位为秒（与秒数的各部分）。
The header at the top of the Timeline indicates time in seconds (and parts of seconds).
结果针对人体的目标拾取运动特征的研究，提出截止目标尺度的概念，推导出人体的目标拾取运动的时间计算方程。
Result the conception of final target size was put forward, an equation for calculating the movement time of target acquisition was obtained, and a new definition of index of difficulty was given.
