radially

基本解釋

And so that energy goes out radially, symmetrically, isotropically in all directions, and so it's very easy.
因此能量是呈放射狀的，對稱的，等傚全曏的輻射,曏各個方曏，因此很簡單。
So they migrate radially—in all possible directions away from the den—like starburst embers from a Fourth of July rocket.
於是，它們呈放射狀移動——從巢穴曏所有可能的方曏遷移——像國慶焰火似的四射開來。
Hopefully, you can see that if I take a normal vector to the sphere it is actually pointing radially out away from the origin.
我希望大家能夠了解,如果我將法曏量平移至球麪,那麼它將以原點爲(wèi)心曏外放射。

er is a vector at each point of length one pointing radially away from the center.
r 是一個模長恒爲(wèi) 1 的矢量,方曏沿半逕曏外
