| 摘 要： | 本文采用 Prigoginc 提出的耗散结构理论,对铝电解中阳极效应的特征进行了分析.认为,阳极效应是一种远离平衡态的耗散结构,它的“阈值”是冰晶石熔液中的 Al_2O_3浓度,进而提出,阳极效应的发生是因为产生超熵的结果,并认为各种熄灭阳极效应方法的共同特点是瞬间引进正熵流.

| Abstract: | The dissipation structure theory by Prigogine is used to discuss the characte-ristics of anode effect in aluminium electrolysis.Such an anode effect is regar-ded as a dissipation structure away from equilibrium state with a thresholdvalue defined as the concentration of alumina in cryolite melt thus deducingthat the anode effect results from super entropy.Introducing instantaneouslythe positive entropy flow into the system is a commonly used way to variouscases of quenching anode effect. |
