摘要翻译：
我们给出了含有少量缺陷的非金属晶体自由能的严格计算。低温超前贡献为$\protoT^2$。这进一步给出了一个线性的低温比热，就像眼镜所显示的那样。这些结果还表明，与玻璃中发生的情况类似，几乎完美的晶体的长波长光谱不足以确定其低温行为。

英文摘要：
We provide a rigorous calculation of the free energy of a non-metallic crystal containing a small concentration of defects. The low-temperature leading contribution is found to be $\propto T^2$. This further gives a linear-in-$T$ low-temperature specific heat as that exhibited by glasses. These results also show that, similarly to what happens in glasses, the long-wavelength spectrum of a nearly perfect crystal does not suffice to determine its low-temperature behavior.
