摘要 分析了一维具有分片常系数的特征值问题集中质量有限元方法,证明了离散特征值具有如下意义的单调性:设网格Jh′是网格Jh的任意加密,λ1′和λ1为相应的近似特征值,则有λ1λ1′. This paper carries out the analysis of the lumping mass finite element method for the one dimensional eigenvalue problem with the pieeewise eonstant eoeffieient. It is proved that the discrete eigenvalue admits the monotone property in the sense that λ1≤λ1′ provided that Jh′ is a refinement of J′ and λ1′ and λ1 are assoeiated diserete eigenvalues on them.
