  further on than we are, time as well; maybe spin even.
  比现在快 也可以加上时间甚至自旋
• 
  
  But that function has to be such that HΨ/Ψ is the total energy,
  但是函数HΨ/Ψ一定是总能量
• 
  
  and the total energy is the same,
  并且总能量是相同的
• 
  
  no matter where the particle is, right,
  无论粒子在哪里 对吗
• 
  
  because the potential energy and the kinetic energy cancel out.
  因为势能和动能可以相互抵消
• 
  
  It's like a ball rolling back and forth.
  它就像一个来回滚动的球
• 
  
  The total energy is constant but it goes back
  总能量是个常数
• 
  
  and forth between potential and kinetic energy, right?
  但是在动能和势能间相互转化 对吗
• 
  
  Same thing here. No matter where the particles are,
  同样的事情是 无论粒子在哪里
• 
  
  you have to get the same energy.
  必定有相同的能量
• 
  
  So Ψ has to be such that
  因此Ψ是这样的
• 
  
  when you calculate the kinetic energy for it,
  当你计算它的动能
