The static frequency modulation characteristic of electric network is the foundation of frequency stability of the electric network that determined by frequency modulation.
由一次调频决定的电网静态调频特性，则是电网频率稳定性的基础。
2
Frequency modulation does not allow static to creep in.
频率调制不允许静电干扰混入。
3
The results clearly show conduction losses are the function of semiconductor static characteristic, power factor, modulation depth and load current.
