平动 meaning in English
[物理学] translation; translational motion
Examples
- The spacing of translational energy levels is very small .
平动的能级间隔极少。 - Often translation and rotation occur simultaneously, as in the case of a rolling drum .
通常平动和转动同时发生，例如，圆筒的滚动。 - The roller supports at a and b prevent transition in the vertical direction but allow rotation .
A和B处的辊轴支承不允许沿竖直方向平动，但允许转动。 - The energy of an atom or molecule is described in terms of translational rotational vibration and electronic energy .
原子或分子的能量，按平动转动振动和电子能来描述。 - In the most general case, a single force acting on a body produces a change in both its translational and rotational motions .
在最普遍的情况下，单一的力作用在物体上，使物体的平动和转动都发生改变。
