摘要：
First results on quark-hadron duality in the spin sector from the HERMES experiment are reported in the range 1.2 less than or equal to Q(2) less than or equal to 12 GeV2 and I less than or equal to W-2 less than or equal to 4 GeV2. A complete set of measurements of the generalised GDH integrals for the deuteron, proton and neutron is also shown in the same 0 2 range and in the full W-2 range.
