radially

基本解释

And so that energy goes out radially, symmetrically, isotropically in all directions, and so it's very easy.
因此能量是呈放射状的，对称的，等效全向的辐射,向各个方向，因此很简单。
So they migrate radially—in all possible directions away from the den—like starburst embers from a Fourth of July rocket.
于是，它们呈放射状移动——从巢穴向所有可能的方向迁移——像国庆焰火似的四射开来。
Hopefully, you can see that if I take a normal vector to the sphere it is actually pointing radially out away from the origin.
我希望大家能够了解,如果我将法向量平移至球面,那么它将以原点为心向外放射。

er is a vector at each point of length one pointing radially away from the center.
r 是一个模长恒为 1 的矢量,方向沿半径向外
