基于作者最近发展的晶态合金电阻理论,本文对Cu3Au电阻率的温度系数随长程有序度增加而增大的现象给出一个解释,用一个简单的模型赝势计算Cu3Au的ρT及(dρT/dT),所得结果与实验资料一致。In this paper, an explanation for the increase in temperature coefficient of electrical resistivity of Cu3Au with increasing degree of long-range order is given on the basis of a recent theory of resistivity for crystalline alloys proposed by the author. The ρT and dρ/dT of Cu3Au calculated by using a simple model pseudopotential appear to be in relatively good agreement with experimental data.
