But since then, scientists have figured out that if you blend several metals that mix with each other freely, but can't easily crystallize together, usually because they have very different atomic sizes, the mixture crystallizes much more slowly.

但是在那时以后，科学家们便发现如果你将几种可以任意混合的金属混合在一起，它们便很难在一起结晶，这往往归因于它们的原子大小不同，它们的混合体结晶就慢了很多。
