當電極反應處於平衡時，電極反應的兩個方向進行的速度相等，此時的反應速度

當電極反應處於平衡時，電極反應的兩個方向進行的速度相等，此時的反應速度叫做交換反應速度。相應的按兩個反應方向進行的陽極反應和陰極反應的電流密度絕對值叫做交換電流密度，

結果 (英文) 1:

When the electrode reaction is in equilibrium, the speed of the two directions of the electrode reaction is equal. The reaction speed at this time is called the exchange reaction speed. The corresponding absolute value of the current density of the anodic reaction and the cathodic reaction carried out in two reaction directions is called the exchange current density,

When the electrode reaction is in equilibrium, the two directions of the electrode reaction proceed at the same speed, and the reaction speed at this time is called the exchange reaction speed. The absolute value of the corresponding current density of anode reaction and cathode reaction in two reaction directions is called exchange current density.
