    I don't know why the circuit which is attached to this post, doesn't
    work as differential amplifier in "Pspice software" when both of the AC voltage sources are "1v " ?

    A differential amplifier amplifies the differential (difference) signal between the two inputs. It ignores common-mode signals (same phase), which is what you appear to be applying. Invert the phase on one of the sources (by 180° or by inverting the connection) and you should see an output.
