The flavor transition mechanisms of supernova neutrinos as they propagate outward from the deep inside of a supernova are yet to be determined. We study the time-evolution patterns of different neutrino flavors in various flavor transition scenarios. With simulation data of supernova neutrinos, we calculate the neutrino event rates at LArTPC for different flavor transition scenarios. Using the calculated event rates of v e Ar in liquid argon detector, we calculate the ratio of cumulative time distribution up to tpb = 100 ms in several supernova neutrino simulations. We show that the time evolutions of cumulative ratios are effective in determining whether the MSW oscillations really occur.
