For vortex-liquid phase,the E-J relation could be described according to the Kim-Anderson model:U=U0(1-J/JC).While for vortex-glass phase,the electric field decays verydramatically with decreasing current density,so it is difficult to be observed with theinstrument has limited precision.In the intermediate current region,the E-Jrelations of the both phases could be fitted in terms of a phenomenological model:U=(U0/μ)[μ-1],it was concluded that the sign of μ-value changes fromnegative to positive when the temperature decreases lower than the glass-transitiontemperature Tg,meanwhile,the activation energy U enhances dramatically.Whilein the large current region,Zeldov's logarithmic model was suitable for fitthing theE-J curves of the both phase.Moreover,there was no abrupt change of U or thecharacteristic current density IC.However,the effective radius of vortex line variesremarkably around Tg.

对于涡旋液体相，小电流区的E-J关系可以用计及反跳的Kim-Anderson模型U＝U0(1-J/JC)来描述，而对于涡旋玻璃相，小电流区的电场随电流密度减小而迅速衰减，以致很快脱离了实验测量精度的范围；在中等电流区，两相的E-J关系可以用共同的唯象过渡模型U＝(U0/μ)[μ-1]来拟合，得到在玻璃转变温度Tg两侧μ值由正到负的变化，同时激活能U在Tg以下迅速升高；在较高电流区，两相的E-J关系可以很好的用Zeldov对数模型来描述，拟合结果表明U在Tg两侧的趋势没有明显变化，但是涡旋线的有效半径发生了显著变化。
