摘要：

We investigate the Q(2) dependence of inclusive electron-proton scattering F-2 structure function data in both the nucleon resonance region and the deep inelastic region, at momentum transfers below 5 (GeV/c)(2). From these data we construct moments of F-2, down to momentum transfers of Q(2)approximate to0.1 (GeV/c)(2). The second moment is only slowly varying with Q(2) down to Q(2)approximate to1 (GeV/c)(2), which is a reflection of duality. Below Q(2) of 1 (GeV/c)(2), the Q(2) dependence of the moments is predominantly governed by the elastic contribution, whereas the inelastic channels still seem governed by local duality.
