在大量的非过渡金属和合金中,非晶态超导体的声子谱参数λ,和2>与霍耳系数R_H之间存在着一个经验关系:在RH=-3.5—-4.0×10-11m3/As之间存在着λ,和2>的最大值。上述声子谱参数与相应的液态金属的霍耳系数RHL之间也存在着一个和上述类似的经验关系。最后讨论了非晶态超导体的转变温度Tc的提高问题。It is found that there is an empirical correlation between phonon spectrum parameters λ, 〈ω〉,〈ω2〉 and the Hall coefficients RH in a variety of nontransition metals and alloys; there is a maximum of λ,〈ω〉 and 〈ω2〉 as RH =-3.5--4.0×10-11m3/As. There is also a similar empirical correlation between λ, 〈ω〉, 〈ω2〉 and Hall coefficients RHL of responding liquid metals. Finally, the question of raising Tc of amorphous superconductors is discussed.
