摘　　要：主要研究了几类图族伴随多项式第四项系数的规律,此结果有助于进一步讨论这些图族补图的色唯一性、色等价划分.In this paper,the properties of the fourth coefficients of adjoint polynomials of four classes graphs are given,and a new method for classifying graphs is also abstained.These results are beneficial to study the chromaticity and chromatic equivalents classify of the complements of these graphs for us.
