用扫频仪测量天线的输入阻抗时，在同轴传输线与天线间应按平衡—不平衡变换器。
When using frequency sweep meter to measure the input impedance of antenna, the balanced - unbalanced transformer must be connected between coaxial transmission line and antenna.
在电力变换器中，不平衡会产生不希望的直流波动以及交流侧无特征的谐波。
In power converters, unbalances generate undesirable DC ripple and non characteristical harmonics in the AC side.
