Abstract：
We show that the recent WMAP data can impose a generous upper bound on the effective masses of electron, muon and tau neutrinos defined in the kinematic measurements:2, +< m>u2+2t = m12 + m22 + m32<0.5eV2, or a<0.71eV ( for a = e, u,t) . When current neutrino oscillation data are taken into account, we obtain (m)?< 0.24eV and u=t< 0.24eV, Thus there is no hope to kinematically detect u and t in any realistic experiments.
