摘要：

We compare the forces generated by various angle-dependent potentials and by ab initio band-structure calculations with a limited number of k points. In cells with 32 and 54 atoms we find substantial errors for all of the angle-dependent-force models, as well as for the band-structure forces with very few k points. © 1990 The American Physical Society.
