• Thus each orbit may be called, alternatively, an energy level .
  因此，每一个轨道也可以交替地称作一个能级。
• Only two of the electrons in the second level reside in hybrid orbitals .
  第二层仅仅两个电子处于杂化轨道中。
• I fell back into my old routine, and took up my real part again .
  我又回到旧轨道上去，扮演起我擅长的角色了。
• And now each side was trapped on a collision course it could not alter .
  现在各方已经陷入无法改变的冲撞轨道。
• the function (1s＋) is a hybridized atomic orbital.
  函数（1s）是一个杂化的原子轨道。
• The shape of a real 2p orbital is two separated, distorted ellipsoids .
  实2p轨道的形状是两个分开的变形的椭球。
• This classification is the analogy of our previous picture of stable orbits .
  这种区分类似于前面的稳定轨道图形。
• The space shuttle can orbit at altitudes of up to 965 kilometers .
  这架航天飞机最高能在965公里的高度作轨道运行。
• The concepts of penetrating and non-penetrating orbits must be modified .
  必须修改贯穿式轨道和非贯穿式轨道的概念。
• The major semiaxis a and p of the relative orbital motion are known .
