Abstract：
The neutrino and antineutrino deep inelastic scattering of unpolarized and polarized A and A productions can provide a clean separation of unpolarized and polarized fragmentation functions of a quark into a A, for both light-flavor quarks and antiquarks and also for strange quarks. One can systematically measure or check the various flavor and spin dependent fragmentation functions by combining with A and A productions in polarized electron deep inelastic scattering. Such measurements can provide crucial tests of different predictions concerning the spin structure of hadrons and the quark-antiquark asymmetry of the nucleon sea.
