交流电桥法测量电化学体系的阻抗,是交流阻抗技术中的一种经典的方法。它需要的仪器简单,测量数据准确,因此在某些需要较准确测量结果的地方有应用价值。但是,交流电桥法在应用上也有局限性,例如,由于分布电容、电感以及主要是市电噪声干扰,测量的频率范围一般在20～20K Hz。这对于许多电化学体 The AC bridge method to measure the impedance of the electrochemical system is a classical method in AC impedance technology. It requires simple instrumentation and accurate measurement data, so it has value for applications that require more accurate measurement results. However, the AC bridge method has its limitations in application. For example, the frequency range of measurement generally ranges from 20KHz to 20KHz due to distributed capacitance, inductance, and mainly noise from the mains. This is for many electrochemical bodies
