附加电阻 meaning in Chinese

added resistance
additional resistance
ballast resistor

The error reasons of low resistance measurement are studied , the theory of removing line resistance error proves to be right with time - domain analysis method and frequency - domain analysis method , and the results proved to be true by the experiment datum with the statistics method
研究了低电阻检测时产生系统误差的原因，分别用时域和复频域两种方法分析了在低电阻检测时消除附加电阻误差的原理；并通过两组实验数据用数理统计的方法验证了附加电阻误差影响已经被消除的结论。
