Abstract: The effect of imaginary potentials on energy spectrum of PT symmetry system is studied.

The conclu- sion of this paper can gives a supplement to the paper named “The properties of energy

spectrum in a non-Hermi- tian system with PT-symmetry”.

Key words: PT-symmetry, non-Hermitian system, energy spectrum, symmetry broken
