To lower the operation frequency I use fixed capacitors in parallel with the variable capacitor.
为了降低操作频率,我用固定电容器,可变电容器并联。

Instead timing circuits use a fixedcapacitor and a variable resistor if it is necessary to vary the time period.
相反定时电路使用固定电容器和可变电阻如果有必要更改的时间期限。

The research on SSSC at home and abroad is reviewed. Finally, the differences between SSSC and fixedcapacitor compensation as well as controllable series compensation are compared.
