如果Γi(α)∩Γ1（β）在每个i和∂(α, β) = i时停留在Δ和α， β λ Δ，则图Γ的测地封闭诱导子图Δ被定义为强封闭。我们研究了高度正则图（如距离正则图或距离双正则图）中强封闭子图的存在条件。
A geodetically closed induced subgraph Δ of a graph Γ is defined to be strongly closed if Γi(α) ∩ Γ1(β) stays in Δ for every i and α, β ϵ Δ with ∂(α, β) = i. We study the existence conditions of strongly closed subgraphs in highly regular graphs such as distance-regular graphs or distance-biregular graphs.
