摘　　要：根据PT-对称量子系统中PT-内积和原内积之间的关系,给出PT-对称量子理论中纯态的刻画以及PT-对称量子系统中混合态的一个刻画,研究PT-对称量子系统中态的演化,并给出其为酉演化的充要条件.Firstly, we gave characterization of the pure state in the PT-symmetric quantum theory based on the relationship between the PT-inner product and the original inner product of PTsymmetrie quantum system. Secondly, we gave the characterization of the mixed state in the PT-symmetric quantum system. Finally, we studied the evolution of state in PT-symmetric quantum system, and gave a necessary and sufficient condition for the unitary evolution.
