• 
  
  So the kinetic energy is positive. Okay?
  所以动能为正
• 
  
  At these places, the potential energy is higher than the total energy.
  而在这些区域 势能高于总能量
• 
  
  So the kinetic energy is negative and
  所以动能为负
• 
  
  the thing is curving away from the baseline. Right?
  而且曲线背着基线弯曲
• 
  
  And now we know something about this point.
  现在我们可以对该点作判断
• 
  
  If the potential energy is a continuous kind of thing,
  如果势能是连续的
• 
  
  then, although we couldn't tell by looking at the wave function,
  尽管从波函数中无法判断
• 
  
  it's curving away from the baseline, but very slightly,
  这一点还是略微背着基线弯曲的
• 
  
  right? It's negative kinetic energy there,
  所以动能为负
• 
  
  and also on the right here is negative kinetic energy.
  同样这里也是负动能
• 
  
  And here we know, just by continuity,
  同样根据连续性
• 
  
  that at this point it must've been positive kinetic energy,
  在这一点动能为正
