摘　　要：在用水做电介质的静电场描绘实验中,如果用直流电源,理论值和实验值偏差较大;如果用交流电源,理论值和实验值则吻合较好。自制了静电场测试仪器并进行实验测试,分析了误差产生的原因,提出了根据实际情况对理论值进行修正的方法。结果表明,采用本文提出的静电场测试仪和修正方法,可以使理论值和实验值较好地吻合。When water was used as the dielectric media in the experiment of describing Electrostatic Fields,different results would be given out if we use different power source. There was a visible difference between experimental data and theoretical value when DC power source was used. However,experimental data and theoretical value are in good agreement when AC power source was used. A kind of Electrostatic Field tester device was made and applied to actual measurement. The deviation was analyzed according to the experimental conditions and a method was put forward to modify the theoretical value. The experimental results showed that the proposed correction method could make the theoretical value and experimental value in good agreement.
