And these rings are indicative of the crystal structure of nickel and can be explained only by invoking wavelike properties of light.

这些光圈,表明了了镍的晶体结构,而且只能通过,光线中波的特征来解释。

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。

There is no way that you could irradiate a crystal of nickel with a single beam of x-rays and get that circular ring pattern if the electron beam were behaving as a particle beam only.

没有什么其他的途径,可以让镍晶体发射,单束X光来,继而得到环状图案,如果电子束,是以粒子束形式出现的。

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。

They took a crystal, this is a single crystal of nickel that has regular planes of atoms, and those planes are spaced on the order of an angstrom or less apart, and they irradiated this with x-rays.

他们取了个晶体,一个具有规则原子平面的，镍晶体,这些面间距差不多也是一埃或者更少，它们放射出X射线。
