Standard calculation of the polarization of final electron for pure initial state may be reformulated as a problem of looking for the complete polarization axis of produced state. It gives method for calculation of polarization applicable for both final and intermediate state fermions. We discuss modification of the energy and spin projectors in theory with parity violation. The obtained projectors are used to give the most accurate parametrization of t-quark resonance curve and simultaneously for its off-shell polarization.
