We have shown that a local-density-dependent term, F[ρ(r)] ρ(r), of the pion-nucleus potential with a nuclear density, ρ(r), can be transposed to a conventional density-linear term, F(ρe) ρ(r), with an effective nuclear density, ρe, which is close to ∼ 0.6 ρ(0) for most π- bound states. The presently found relations, \it generalized Seki-Masutani relations, for the density-quadratic term, the medium-modified isovector term and the double-scattering isoscalar term of the s-wave pion-nucleus interaction assure that the constant parameters in the conventional pion-nucleus potential are interpreted as being effective ones in the light of density-dependent effects.
