Query: Two Contrastive Boson-Pair Coherent States in Deformed Boson Scheme   Two types of boson-pair coherent states, which were proposed independently by
the present authors, are investigated. Main conclusion is as follows : Although
the two states are superposed contrastively in terms of the boson-pairs, the
expectation values of the boson-pair operators for these states are the same as
one another with high accuracy.
