如果人体组织和电极之间的有效接触面积保持不变，那么高频电流强度扩大一倍将会使电流密度增大一倍，并产生四倍的热量。
Doubling hf-current results in a doubling of current density and a fourfold heat provided that the area of effective contact between the tissue ang the electrode remains constant.
使用陶瓷纸作电极的电池也因此能够快速充电，但在高电流密度时同样会快速放电。
Batteries with ceramic paper electrodes could therefore be charged quickly, but also discharged quickly to allow for high current densities.
讨论了电极活化条件、电流密度、电解液温度等因素对电解还原反应的影响。
