potential shift meaning in Chinese

电位偏移
势移

The optimal cp potential shifted to negative direction in seamud containing active srb , - 1030 mv ( vs . saturated cu / cuso4 electrode , cse ) or lower potential was needed . accordingly , the cp current density was about 11 ma / m2
在srb存在下，最佳阴极保护电位移向更负的值， - 1030mv （相对铜/硫酸铜电极， cse ）甚至更低的电位是需要的。在- 1030mvcse保护电位下，保护电流密度约为11ma / m2 。
