Abstract: We mainly study the isomorphism, isomorphism group, homomorphism, center and normalizer of some special Lie subalgebras h₁, h₂, h₄, h₅ and h₁₀ of extended infinite dimensional Lie algebras Schrodinger-Virasoro. Firstly, we construct the isomorphism of Lie subalgebra h₁, and obtain that its isomorphism group is isomorphic to integer plus group. At the same time, we construct and prove that the Lie subalgebras h₄ to h₅ are isomorphic, and the isomorphism group is isomorphic to non-zero complex group \bfC^*. Finally, it is proved that the center C (h₁₀) = 0.
