摘　　要：We study ^（87）Rb Bose-Einstein condensation（BEC） loading into the pulse of the one-dimensional（1D） optical lattice experimentally.The lattice is turned on abruptly,held constant for a variable time,and then turned off abruptly.The measurement of the depth of the optical lattice is obtained by Kapitza-Dirac scattering.The temporal matter-wave-dispersion Talbot effect with ^（87）Rb BEC is observed by applying a pair of pulsed standing waves（as pulsed phase gratings） with the separation of a variable delay.We study ^（87）Rb Bose-Einstein condensation（BEC） loading into the pulse of the one-dimensional（1D） optical lattice experimentally.The lattice is turned on abruptly,held constant for a variable time,and then turned off abruptly.The measurement of the depth of the optical lattice is obtained by Kapitza-Dirac scattering.The temporal matter-wave-dispersion Talbot effect with ^（87）Rb BEC is observed by applying a pair of pulsed standing waves（as pulsed phase gratings） with the separation of a variable delay.
