  Using the way of deriving infinitive sum representation of density operator
as a solution to the master equation describing the amplitude dissipative
channel by virtue of the entangled state representation, we show manifestly how
the initial density operator of a single-mode squeezed vacuum state evolves
into a definite mixed state which turns out to be a squeezed chaotic state with
decreasing-squeezing. We investigate average photon number, photon statistics
distributions for this state.
