• 
  
  The total energy is lower than the potential energy.
  总能量小于势能
• 
  
  The difference is negative. Okay?
  它们的差别是负值
• 
  
  So the kinetic energy, if that's the difference,
  如果动能是势能和总能量之间的差别
• 
  
  between potential and total, is negative.
  那这个差别就是负值
• 
  
  You never get that for p=1/2mv2. Yes?
  根据动能公式不可能得到这个结果
• 
  
  Does this violate that Ψ has to remain finite?
  是因为函数Ψ违反了有限的规定吗
• 
  
  Does it violate what?
  违反了什么
• 
  
  That Ψ has to remain finite?
  其必须有限
• 
  
  No. You'll see in a second.
  不是 过会你就会明白
• 
  
  Okay, so anyhow the constant potential energy
  总之该情况下恒定的势能
• 
  
  is greater than the total energy for that.
  比总能量高
• 
  
  Now, how about if it were minus exponential, e-x?
  那如果是e的-x指数呢
