Probing of spin degree freedom:test the dynamic of SM.Λ/(Λ)transverse polarization(TP)significantly observed at BESⅢ in J/Ψ or continuum processes.In the case of absence of polarized beam,TP provide us with a powerful tool to study the CP violation in s-/c-hyperon decays.Polarized beam in the future super-tau charm facility(STCF)help to improve the precision.
