| 摘 要： | The analytical expressions of eigenstates and eigenenergies are demonstrated using a parameter A without theassumption of Bethe ansatz for two kinds of five-mode mixing models. It is found that the parameter can bedetermined by the roots of a simple polynomial. We also illustrate the exact analytical expressions of eigenstatesand energies without any unknown parameter.
