摘要：
Neutrino scattering on the nucleon, and charged lepton scattering on the nucleon provide information on the parton (quark and gluon) distributions in the nucleon. Unpolarized parton distributions represent how the nucleon's linear momentum is shared with quarks and gluons. Recently, the spin structure of the nucleon has also been studied. Polarized parton distributions show how the nucleon spin, 1/2, is constituted by quarks and gluons. Neutrino-nucleon elastic scattering can contribute to the study of the strangeness-quark spin in the nucleon.
