为了克服银-氯化银的三分量传感器测得的测量值与电场发生器标准值存在的误差,设计了传感器支架和外加测量体影响电场测量值的实验.在电位和电流连续的条件下,运用麦克斯韦方程组,计算了规则球形测量体引起的电场畸变,并进行了实验验证.实验结果表明,测量体引起的电场畸变不可忽略;测量体处于电极内部会增大测量的电场,处于外部时将降低测量的电场;当测量体离测量电极比较近时,影响较大,反之,影响较小.

In order to overcome the errors occurred between the measured value by Ag-Agcl three-component sensor and the standard value of electric field generator, this paper designs an experiment on the sensor bracket and extra measurement body affecting the electric field’s measured value. In this paper, the electric field distortion caused by regular spherical measurement body is calculated, by using the Maxwell equations under the condition of continuous potential and current, and proved by experiments. Experimental results show that the electric field distortion can not be neglected, the measurement body inside the electrode would increase the measured electric field and lower the measured one while the body being outside; the effect is greater when the body is more approaching to the electrode, and conversely, the effect is less.
