exchange currents meaning in Chinese

互换流

Through compare the exchange current scheme with the direct current scheme , we have chosen the direct current scheme , go on detailed parameter calculate and the selecting type of the equipment
经过对直流方案和交流方案的比较，选择了直流方案，并进行了详细的参数计算和设备选型。
But the comprehensive properties were improved remarkably . with the addition of carbon nanotubes , the polarization of charging process decreased , the plateau of discharge became flatter and the migration of potential of peaks value of cyclic voltemmograms reduced . for the other hand , the exchange current increased , ohm resistance and electrochemical reaction resistance of the electrodes decreased , the diffusion resistance of hydrogen and the resistance of adsorption decreased , too
掺入碳纳米管对储氢合金电极的容量影响较小，但其电化学性能却有较大的改善，主要体现在：充电的极化减小，放电平台更加平稳、循环伏安曲线的峰值电位随扫描速度增大的迁移量减小，交换电流密度增大，电极的欧姆电阻、电化学反应、扩散电阻和吸附电阻均减小。
