We measured the variations of quasiparticle tunneling current It of the detector junction of a Pb-I-Pb-I-Pb junction with the injection current Ii in the range Vtt and Ii is approximately parabolical, after the appearance It increases much faster. The difference △It = It-It0, where It0 is the tunneling current in equilibrium state, decreases with the decrease of temperature.
