摘　　要：It is proved that the additive inverse eigenvalue problem is equivalent to a polynomial system. By studying the system we obtain some new sufficient conditions on the solvabitity, and some numerical methods. Some numerical examples are presented.It is proved that the additive inverse eigenvalue problem is equivalent to a polynomial system.
