摘要：

We show that using measurements of the longitudinal sound velocities in UPt3 in conjunction with the results of a model for the double superconducting transition in an unconventional superconductor it is possible to derive a number of thermodynamic parameters. The values derived for these parameters differ considerably from those obtained from direct measurements. This suggests that there are possibly other factors not considered in present theory which influence the ultrasound velocity in UPt3.
