This proved not only the wave nature of X-rays but also the three-dimensional periodicity of a crystal.

这不但证明了X射线的波动性，还确定了晶体的三维周期性。

Because of quantum wave nature, cold atoms tunneling through a laser beam can obviously have a completely different feature from that of a classical particle (hot atom).

量子力学波动性使得冷原子穿越一个激光束时明显地展现出与经典粒子(热原子)不同的结果。
