arc length

基本解釋

Well, so in particular,how do you relate arc length and time?
尤其是你怎麼把弧長和時(shí)間聯(lián)系起來？
But, in this case, if you are moving back and forth, it would make more sense to have the arc length first increase, then decrease,increase again, and so on.
在這種情況下，如果在來廻運(yùn)動(dòng)，第一次增長的弧長更有意義，接著減少，再增長，諸如此類。
I mean, that would be sneaky-freaky, but you could have a negative arc length that gets 0 closer and closer to zero, and gets to zero at the end of a trajectory, or anything you want.
這也許有點(diǎn)怪怪的，但隨著距離0點(diǎn)越來越近，可以得到負(fù)的弧長,在軌跡終點(diǎn)達(dá)到，或者你想去的地方。

He piggybacks this unit directly on top of a scope, allowing him to produce never-before-captured wide-field images, like his striking, ghostly picture of Barnard's Loop-a huge arc of gas that covers the length of the constellation Orion.

弧長
The fuzzy arc length controller is established with arc voltage as the input and wire speed as the output, based on the MATLAB software.
