The closed expressions with a parameter of the Bogoliubov unitary transformation are derived. The reduced Hamiltonian of the quantum Bose fluid is diagonalized in the original particle number representation. The manifestation of nonclassical character in the two mode radiation is extended to the quantum Bose fluid. Finally, the eigenstates of the Hamiltonian are established to be the squeezed boson pair number states with a nonclassical character.
