摘　　要：探讨了"哪些图由它的Laplace谱确定?"的问题,利用同谱证同构的方法,证明了具有特殊结构的路Pn,星K1,n,圈Cn,毛毛虫W等,各自由它们的Laplace谱确定。The problem on“what graphs were determined by their Laplace spectra” was discussed. By using the properties of cospectral graphs, some graphs with special structure were proved, such as the path Pn, the star K1,n, the cycle Cn and larva W, are determined by Laplace spectra, respectively.
