能级

• Thus the second-lowest energy level of the particle in a cube is threefold degenerate .
  于是立方体中的第二最低能级是三重简并的。
• The energy separation between these two levels was calculated in problem 10-17 .
  这两个能级之间的能量差在习题10-17中已经计算过。
• This fact is often expressed in the physics jargon as "energy levels repel each other. "
  用物理术语来说，这一事实常称为“能级的相斥”。
• The rotational levels of the ground vibrational level may be depopulated by radiation .
  基态振动能级的各转动能级的粒子数可能因幅射而减少。
• for nondegenerate(δ)levels, there is no element of choice in the wave function.
  对非简并的（）能级，波函数没有选择的余地。
• In other words the whole spectrum of levels is just like that of an alkali turned upside down .
  换句话说，整个能级谱恰好就像是上下颠倒的碱金属能级谱一样。
• Bound indicates that a particle in one of these levels will remain attached to the force center .
  束缚是指位于这些能级中某一能级上的粒子将总是受到力心的约束。
• Differences between the energy levels of molecules are the sources of energy for all living cells and organisms .
  所有活细胞或生物体能量的来源是分子能级的差别。
• The smallest energy transitions are between rotational levels; the next smallest between vibrational levels .
  在转动能级之间的能量跃迁最小，其次是振动能级之间的跃迁。
• For the moment, we shall only be interested in the levels that arise from excitations of the outer electrons .
  就目前而言，我们将只对由外层电子的激发所形成的能级感兴趣。
