英文摘要：
In this paper, we examine the structure of strongly regular graphs with parameters $λ= 1$ and $μ= 2$. In particular, we provide a complete classification of induced subgraphs of order seven and determine their relative frequencies. These findings contribute to a finer understanding of the local structure of such graphs and may be useful in related combinatorial and algebraic investigations.
