First, we study the relation between the translational temperature of the molecular beam and the temperature of the beam source chamber;

首先，我们研究了超声分子束的纵向平动温度和中心速度与束源温度的关系；

Just in the sense that if we look at the contribution of the translational energies at room temperature, they're going to be the same.

他们平动能的贡献，在室温，是一样的。
