The Application of The Property of Minimum Root of Graph's Adjoint Polynomal

本文用国的伴随多项式最小根的性质，给出了关于图的伴随唯一性的两个已知重要结果的简化证明。

n this paper,we make use of the property of the minimum root of graph's adjoint poly-nomal,to give the simple prove of two known important results about the adjoint uniquenessof graph.
