然而电子显微镜采用电子束而不是光。

But electron microscopes use beams of electrons, instead of light.

只有相对原始状态的材料才拥有兰德曼所需要的研究对象，因此他的研究小组必须使用利用电子束表面成像的扫描电子显微镜(下图)去寻找最好的珍珠层。

Only relatively pristine material has the goods Landman is after, so his team USES a scanning electron microscope (below), which utilizes a beam of electrons to image surfaces, to find the best nacre.

扫描电子显微镜是通过扫描聚焦在物体上的电子束来工作的。

The microscope works by scanning a focused beam of electrons across an object.

If de Broglie is correct, let's irradiate the nickel crystal with a beam of electrons where the wavelength of the beam of electrons is identical to the wavelength of the x-rays that were used and see what we get.

如果德·布罗意是正确的，那么镍晶体放出,电子光束,电子束的波长,和原来讲过的X光的波长是相等的,再看看得到了什么。
