摘　　要：For a physically acceptable quantum system,its dynamical evolution is generally governed by a Hermitian Hamiltonian.A Hermitian Hamiltonian ensures a real spectrum and guarantees that the evolution is described by a unitary operator.However,in 1998,Bender and Boettcher[1]demonstrated that,Hermiticity is not a prerequisite for achieving a real spectrum.
