摘　　要：研究了一个无损测量原子质心动量的精确可解模型，详细分析了无损测量的条件及无损测量的动力学过程。文中分析表明，绝热极限是实现此类模型无损测量的必要条件。最后针对此模型讨论了量子无损测量与表象之间的关系。An exactly-solvable model for quantum non-demolition measurement (QNDM) of the momentum of atomic mass-center is studied with the discussions about the conditions and the dynamic process for this QNDM. It is shown in this paper that the adiabatic conditions are necessary for the realization of this kind of QNDM. Finally, the relations between the QNDM and the picture in quantum mechanics is analyzd for this model.
