而且有种X光衍射的技术。

And there is a technique known as X-ray diffraction.

最后计算分析了多矩孔菲涅尔衍射的光强分布。

At last the light intensity distribution of Fresnel diffraction at several rectangular apertures is calculated and analyzed.

这是一个极不错的数字，还没有到衍射的极限。

This is an excellent figure, not that far from diffraction limited.

And the result is a diffraction pattern that produces a series of rings.

得到的衍射图案是,一系列光圈。

And at first this was done by Davidson and Germer, and they were American scientists who tried diffracting electrons from a nickel crystal.

这个实验首先是由，美国科学家Davidson和Germer完成的,他们尝试从镍晶体中衍射电子。

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 of x-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？
