The ∧^(0) polarization is analyzed with the experinental data in S+Pb collisions at energy 200GeV per nucleon,which were produced at SPS of CERN.The snall.polarization rxalue and thecorrelation betrween the transverse polarization and transverse momentum were obtained in Feyn-man parameter x_(F)>0,r_(F)<0 and all xp.The results show that the non-polarization of lamb-da appears in the vegion of larger transterse momenta,say,at 1-2 GeV/c in P_(T).The originsof polarization reduction are discussed.
