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，等效全向的輻射,向各個方向，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.
于是，它們呈放射狀移動——從巢穴向所有可能的方向遷移——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,如果我將法向量平移至球面,那么它將以原點為心向外放射。

er is a vector at each point of length one pointing radially away from the center.
r 是一個模長恒為 1 的矢量,方向沿半徑向外
