In addition, an adjustable resistor is connected in series in the series loop of the sensing unit and the inclusive unit to realize the fine regulation to the power frequency impedance.
此外在所述感性单元和容性单元的串联回路中串入一可调电阻，实现对工作频率阻抗的精细调整。

Be the adoption of redundancy optimization, self-designed adjustable installation structure of loop coder, redundancy switching and fault warning functions of the loop coder were developed.
采用冗余优化，自行设计实施活套编码器可调式的安装结构，开发出活套编码器的冗余切换和故障报警功能。
