摘要：

We show in this paper that care must be exercised when applying Kohler's rule to the magnetoresistance of some conductors, including high-T-c superconductors, where the density of charge carriers might change with temperature T. The rigorous form of Kohler's rule is used in corroboration with other transport data, such as the Hall coefficient. The result suggests that a single relaxation rate offer a reasonable explanation on the normal-state in-plane transport processes of high-T-c superconductors. (C) 2001 Elsevier Science B.V.
