摘要： 多晶体β"-铝的超声吸收的测量揭示出低温下存在着吸收峰[1].这种吸收峰是平宽而非对称的,不同于Debye理论得到的对称峰.形成这种超声吸收峰的原因常常归结为一种连续弛豫现象,即假定存在一个弛豫时间分布g(τ),这时每单位波长的超声吸收系数α由所有弛豫时间的贡献决定.

Abstract: A new interpretation of the broad asymmetrical attenuation peak observed experimentally in the superionic conductor β"-aluminium is given on the basis of the infrared divergent theory which was developed for the excitation and de-excitation processes of the correlated states in the conductor. Both true and apparent excited energies have been obtained rather simply.
