To explore the physical mechanism and the essence of the quantum diffraction in time-domain, the wave function diffraction in time-domain of a two-level system under the pulse field with a chirped frequency is investigated by means of the density matrix equation and the Bloch vector model. The modulations of the quantum diffraction by the chirped factors are discussed. The dynamic evolution process of the population transfer and the effect of the quantum diffraction with different chirped factors are analyzed. The interaction mechanism and the physical process can found a clear description in the Bloch vector picture.
