摘要

Recently studies of flux relaxation of YBCO in the wide time window have been successful. One also meets the problem of parameter uncertainty in nonlinear fitting. In this Letter an analytic solution of the flux equation of motion of the vortex glass or the collective pinning model is obtained by inversion. The comparison of the calculated results with experimental data shows a satisfactory agreement. The problem of parameter uncertainty is solved successfully. The comparison results clearly support the vortex glass or collective pinning model. An empirical relaxation law (called here the ArcG law) is suggested and discussed.
