一种材料的德拜温度的测定被认为包含一些模糊性，因为德拜温度取决于温度和测量方法。然而，在O K的极限下，弹性连续体的德拜近似对实际晶体是有效的，并且由低温热容、弹性常数和中子非弹性散射得到的德拜温度变得很一致。本文综述了测定德拜温度的各种方法，以及德拜温度与成分的关系。利用各种材料的数据，讨论了德拜温度与材料的等温压缩率、熔点、扩散常数、热膨胀系数和生成热等物理性质之间的关系。
The determination of the Debye temperature for a material is thought to include some ambiguity, since the Debye temperature is dependent on temperature and the method of the measurement. At the limit to O K, however, the Debye approximation of an elastic continuum becomes valid for real crystals and the Debye temperatures obtained from the low temperature heat capacity, the elastic constant and the neutron inelastic scattering become in good agreement. Various methods to determine the Debye temperature, and the temperature and composition dependences of the Debye temperature have been reviewed. Correlations between the Debye temperature and physical properties of materials such as isothermal compressibility, melting point, diffusion constant, thermal expansion coefficient and heat of formation have been discussed using the data of various materials.
