摘　　要：壳层模型是原子核结构研究领域最为成功的模型之一,制约其广泛应用和发展的主要原因就是对于某些原子核,其组态空间太大.原子核配对壳模型的提出,使得利用壳模型讨论中重质量原子核的性质成为可能.介绍如何在原子核配对壳模型中引入Lanczos算法,以便未来利用该模型讨论中重原子核的相关性质.Nuclear shell model is one of the most successful model in nuclear structure theory. Because the model space increases dramatically with the increase of the valence nuclei, it is cannot be used extensively. Nucleon-pair shell model makes it possible to study the properties for medium-heavy nuclei in the framework of the shell model. The lanczos method is introduced in the Nucleon-pair shell model, and the properties for medium-heavy nuclei can be studied within the nucleon-pair shell model.
