But for now let's simply say that we have a diffraction which we know occurs only by wave-like behavior and it involves the use ofx-rays. Why x-rays?
但现在让我们来简单假设一下，我们知道，只波才发生衍射，而且衍射涉及了X光的使用，为什么是X光？

In this widely used technique, x-rays are directed through crystals of a protein, and its structure deduced from the pattern of diffraction of the beam.
利用这项广泛应用的技术，X射线直接从一个蛋白穿过，它的结构可以通过光束的衍射类型推断出来。

As the x-rays pass through and bounce off of atoms in the crystal, they leave a diffraction pattern, which can then be analyzed to determine the three-dimensional shape of the protein.
