为了揭示波函数时域衍射的物理本质，采用密度矩阵的矢量模型方法，研究线性啁啾脉冲光场作用下二能级系统波函数的时域衍射效应；讨论光场啁啾因子对时域衍射效应的调制作用；分析不同啁啾因子作用时，量子系统粒子布居转移和时域衍射效应的动态演化过程。在布洛赫矢量表象下，对时域衍射效应的物理作用机制给出了清晰的描述。

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.
