  So it's just you sort of push buttons
  你只需要按几下按钮
• 
  
  and you get where the atoms are in the molecule --
  就可以知道分子中原子的位置
• 
  
  at least that's the hope --
  至少我们希望如此

  and it costs about $200,000.
  它的价格大约是20万美金

  Okay, so there's a little thread there that has a crystal on,
  这边有一根小线 晶体就在它上面
• 
  
  but you need a magnifying glass to see it.

  You won't see it with your eyes; it's a tiny, tiny crystal. Okay?

  So here's an x-ray tube.
  这是x射线管
• 
  
  X-rays come down the pipe there,
  x射线经过管路
• 
  
  hit the crystal and get scattered,
  打到晶体上 然后发生散射
• 
  
  and are detected by this CCD detector. Okay?
  并由CCD检测器进行检测
• 
  
  And then from that information, those scattered rays,
  根据这些信息 也就是这些散射射线
