When the effective phonom spectrum is calculated from the electron tunneling spe-ctrum by invertion of strongly coupled superconducting energy gap equation, the electron density of states must be measured under the condition T→OK. Otherwise the error of the electron density of states and the deviation of effective phonon spectrum from the real one will be very large. In this paper a method is given for correcting this temperature effect, and the above-mentioned difficulty can be overcome. The correct effective phonon spectrum, andλand μ* values can be obtained by this method using electron tunneling spectrum data measured even at T/Tc=0.22.
