摘　　要：针对目前用模拟法描绘静电场实验中所采用的直流电源及导电纸进行静电场的模拟描绘所存在的一系列缺陷 ,介绍一种适合于水槽法进行模拟描绘 ,输出为30 0 0 Hz,0～ 1 0 V,采用交流比较式测量电路 ,直流检流计检流 ,仪器误差较小 ,具有稳定工作性能的交流信号源 .Taking into consideration of serial defects existing in the experiment of “Simulated Static Electric Field Tracing” where DC power source and conductive paper are employed, a cistern method for simulated tracing is introduced where the output frequency is 3 000 Hz, output voltage 0 10 V, and an AC comparison measuring circuit and a DC galvanometer are adopted. Therefore, the instrumentation error is less and the AC message source operates with a stable performance.
