摘　　要：Two-mode Fock space, as a Hilbert space spanned by two-mode occupation number state vectors, is widely used in quantum mechanics and quantum optics. In this work we derive some new operator identifies in this space which can help us to prove a completeness relation in the two-mode Fock space. Let a(a^+) and b(b^+) be annihilation (creation) operators of two-mode
