  So that's a pretty complicated thing.
  这是个相当复杂的公式
• 
  
  So if we want to get our heads around it,
  所以如果我们想要理解这个
• 
  
  we'd better simplify it.
  我们最好简化它
• 
  
  And oh also there's a minus sign;
  这里有一个负号
• 
  
  it's minus, the constant is negative that you use.
  它是负的 你使用的常数是负的
• 
  
  Okay, now let's simplify it by using just one particle,
  现在我们来简化它 只用一个粒子
• 
  
  so we don't have to sum over a bunch of particles,
  所以我们不用为整群粒子求和
• 
  
  and we'll use just one dimension, x; forget y and z. Okay?
  我们只用一个维度x 忽略y和z
• 
  
  So now we see something simpler.
  所以我们可以看到简单些的公式
• 
  
  So it's a negative constant times one over the mass of the particle,
  是一个负常数乘以一个粒子的质量分之一
• 
  
  times the second derivative of the function,
  乘以波函数的二阶导数
• 
  
  the wave function, divided by Ψ.
  再除以Ψ
