正如前一章所示，许多固体是由形成紧密排列的假球形颗粒组成的。这样布置的自由空间约占总容积的26%。现在让我们看看当我们熔化这样一种固体，例如铜，会发生什么。实验表明，其体积增加了3%。更具体地说，是空闲空间从26%增加到29%。原子将有一定的空间从它们原来的位置移动，这样母体晶体的理想秩序就被破坏了。
As was shown in the previous chapter, many solids are composed of pseudospherical particles forming close-packed assemblies. The free space in such an arrangement amounts to about 26% of the total volume. Let us now see what happens when we melt such a solid, e.g., copper. Experiment shows that its volume increases by 3%. More specifically, it is the free space that increases from 26 to 29%. The atoms will now have some room to budge from their proper places, and so the ideal order of the parent crystal is destroyed.
