  if you compress the bond the energy goes up.
  压缩键能量也上升
• 
  
  And that's the wavefunction
  那就是表示
• 
  
  for the position of the hydrogen atom. Right?
  氢原子位置的波函数
• 
  
  Now suppose we increase the mass and instead of
  现在假设我们增加质量
• 
  
  talking about a hydrogen atom we talked about a carbon atom
  用碳原子替换氢原子
• 
  
  which had say fourteen, depending on which isotope we're using --
  比如用碳14那么质量就变为14
• 
  
  suppose we went to fourteen. How is that going to change things,
  质量增加到14那情况会如何变化呢
• 
  
  if we have mass -- can we use the same function,
  如果质量变为14
• 
  
  if we use mass of fourteen?
  还能用同一个波函数吗
• 
  
  Notice that we're using the same potential.
  注意我们仍使用同一个势能
• 
  
  So the kinetic energy at any point
  所以对于这两种情况
• 
  
  is going to be the same for the two.
  动能在何时都是相同的
