The thermodynamic critical field of superconducting state, the jump of the specific heat at Tc and the behaviors of the specific heat below Tc have been calculated by using the modef and the gap equations given in Ref 1 . It is shown that the critical values of the thermodynamic quantities are qualitatively in agreement with the experimental results,and the behaviors of the specific heat are in accordance with those results of CeCu2Si2 and UBe13 at all temperatures.
