Abstract ：An
measurement accuracy ofthe auto source balance circuit is negligible. And the method can greatly improve the
convergence
constructed
for high precision capacitance transmissiononly by the auto source balance method. The bridge can transmit
capacitance with an uncertainty of 3×10 (k=1) at 1592Hz.

发展起来的技术[1] 。
由于感应耦合比率器件具有高准
交流电桥法是电磁测量技术的一个重要部分 。用
高稳定性及很强的抗干扰性能等一系列优点，
交流电桥法进行阻抗的测量属于比较（差值）测量法。
因此感应耦合比率臂电桥得到了迅速的发展和推广。
它比直接测量阻抗具有更高的准确度，仍是目前最准
结合交流阻抗的两端对或四端对定义
