能量

• The energy contained in light comes in little packets .
  光蕴含的能量是一小份一小份的。
• The result in either case is an energy deficiency .
  不论哪种情况结果都会导致能量损失。
• There is no doubt they are responsible for solar energy .
  这就是太阳的能量，毫无疑问。
• All these energies may be interconverted without loss .
  各种能量可以无损耗地互相转换。
• Energy can be converted from one form to another .
  能量可以从一种形式转变为另一种形式：
• An electron in the innermost orbit has the least energy .
  最里面的轨道上的电子能量最低。
• This energy is then dissipated by dry frictional resistance .
  这种能量被干摩阻力所耗尽。
• No reference is made to molecules or to molecular energy .
  没有涉及各个分子或分子的能量。
• Energy is the flame of life .
  能量是生命之火。
• The law of conservation of energy also takes a simple form .
  能量守恒定律也获得简单的形式。
