摘　　要：本文研究了定义在正则度量树Γn上满足δ'-型顶点条件的Schrödinger算子的谱结构。文章首先给出了正则量子树分解后得到的量子线图上的算子所满足的顶点条件与正交多项式的关系,然后根据L2(Γn)的空间分解定理和正交多项式根的性质得到了Γn上算子的谱结构。In this paper, we study the spectral structure of Schrödinger operators with δ'-type vertex condi-tions on regular metric trees. We first give the relationship between the operators with δ'-type vertex conditions on the quantum graph after the decomposition of the regular quantum tree and the orthogonal polynomials;then we get the spectral structure of Schrödinger operators on regular metric trees by the space decomposition theorem and the roots’ properties of orthogonal polynomi-als.
