adj.平移的(直线的)
The spacing of translational energy levels is very small. 平动的能级间隔极少。
The laws of physics are symmetrical for translational displacements. 物理定律对平移是对称的。
Relative coordinates are invariants for translational coordinate systems. 相对坐标与平移坐标系无关。
This curvature of the flow field alters the pressure distribution and the aerodynamic forces from their values in translational flight. 流场的弯曲使压力分布和空气动力与直线飞行时的值相比发生了变化。
The energy of an atom or mulecule is discribed 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。
