常見例句雙語例句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(duì)稱的,等效全向的輻射,向各個(gè)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(dòng)——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(diǎn)為心向外放射。原聲例句er is a vector at each point of length one pointing radially away from the center.r 是一個(gè)模長恒為 1 的矢量,方向沿半徑向外耶魯公開課 - 基礎(chǔ)物理課程節(jié)選 返回 radially
