摘要：

We present a next-to-leading order QCD analysis of the presently available data on the spin structure function g(1) including the final data from the Spin Muon Collaboration. We present results for the first moments of the proton, deuteron, and neutron structure functions, and determine singlet and nonsinglet parton distributions in two factorization schemes. We also test the Bjorken sum rule and find agreement with the theoretical prediction at the level of 10%. [S0556-2821(98)07117-3].
