从双色激光场中运动原子的受激跃迁速率和激光场对原子的辐射压力关系出发，讨论了运动原子在驻波场中的速度聚集效应产生的原因及其与多光子过程的关系。给出了聚速效应出现的条件，预言了极值聚速速度的存在。通过简单的变换，将驻波场中原子速度聚集效应的相应结论推广至双色激光场。
Based on the excited transition rate of the moving atoms in the two-color laser field and the relationship between the laser field and the radiation pressure of the atoms, the reasons for the velocity accumulation effect of the moving atoms in the standing wave field and their relations with the multiphoton process are discussed. The conditions for the occurrence of the polyact effect are given, and the existence of the exponential velocity is predicted. By simple transformation, the corresponding conclusion of the atom velocity aggregation effect in the standing wave field is generalized to the two-color laser field.
