【Abstract】 Based on the phenomenal process of electrical conductivity of CuCr alloys, a 3-D unit net model is put forward. By this model, the influence of the ratio of components and its density upon the conductivity is studied. The results approves the effectiveness of the model by comparing it with typical experimental value.更多还原
