摘要
本文提出了纯金属电阻率与声子浓度及声子平均动量的平方成正比的统计模型，由此简化模型．给出了纯金属电阻串的一个解析表达式，理论与实验规律相符，即在高温时，电阻率与温度Ｔ成正比，低温时与Ｔ￣５成正比．
A statistical model for the electrical resistivity of ideal metals is proposed that the elec-trical resistivity of a ideal metal is directly proportional to the phonon concentration and the square ofthe phOnon mean momentum. The temperature dependence obtained from the theoretical formula arecoincident with the experimental facts that the electrical resistivity is directly proportionaI to tempera-ture T at high temperature and to T^5 at low temperature.
