In Kasner space-time, we calculate the interference phase and oscillation length of the mass neutrinos in some special cases and find that the phase along the null is equivalent to the half phase along the geodesic in the high energy limit. When the parameter a in line element fulfils a=0, the interference phase is the same as that in Schwarzschild space-time. Research on this subject has impact on cosmology.
