摘　　要：针对输入电流相移产生的相角测量误差,提出了基于参考电阻的淡水鱼阻抗测量方法.通过串联参考电阻,利用被测鱼体电压信号与参考电阻电压信号相位的差值来确定鱼体阻抗.把测量结果与Agilent 4294A分析仪测试结果进行比较,鱼体阻抗幅值最大相对误差为0.45%,相位角的最大相对误差为4.44%,说明该方法测量精度较高.For the phase angle measurement errors resulted from phase shifts of input current, the series reference resistance method is presented. The measured fish impedance related to series reference resistor can be acquired through the corresponding relationship between the reference resistance and the measured fish voltage. Compared with the Agilent 4294A analyzer, the method can improve the higher measurement accuracy of freshwater fish impedance.
