我们从微观和热力学角度重新考虑与肮脏的 II 型超导体中涡线运动相关的热流，并表明卡罗利和 Maki 之前使用的热流算子 ${{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}_{0}}^{h}$ 必须替换为 ${\stackrel{\ensuremath{\rightarrow}}{j}}^{h}$存在恒定磁场 $H:{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{h}={{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}_{0}}^{h}+H{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{M}$，其中${\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{M}$ 可称为磁化电流。然后，我们重新计算在所有温度（以及高场区域）下与单个涡线 ${S}_{D}$ 相关的熵，该熵在低温下像 $T$ 一样消失。
We reconsider microscopically and thermodynamically the heat current associated with the motion of vortex lines in a dirty type-II superconductor and show that the heat-current operator ${{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}_{0}}^{h}$ employed previously by Caroli and Maki has to be replaced by ${\stackrel{\ensuremath{\rightarrow}}{j}}^{h}$ in the presence of a constant magnetic field $H:{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{h}={{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}_{0}}^{h}+H{\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{M}$, where ${\stackrel{\ensuremath{\rightarrow}}{\mathrm{j}}}^{M}$ may be called the magnetization current. We then recalculate the entropy associated with a single vortex line ${S}_{D}$ at all temperatures (and in the high-field region), which vanishes like $T$ at low temperatures.
