For an asymmetric beam-splitter a new kind of entangled state 
is introduced, we then derive the integration
measure with which such states can make up a complete and orthonormal
representation in two-mode Fock space. We then show how to use in finding new squeezing operator and new
squeezed state, whose generation can relies on the asymmetric beamsplitter.
