On the basis of the studies above, the minimum power supply frequency favorable to uniform glow discharge was formulated.

在此基础上，根据大气压下有利于均匀辉光放电的放电条件，最终推算出有利于均匀辉光放电的最小电源频率。

In this process, the supply frequency of the motor is not changed; it is always identical to the relevant mains frequency.

在此过程中，电机的供应频率是不变的。它总是与相关的主频率相同。

To keep power flowing reliably, grid operators must smooth out supply and demand on a second-to-second basis (known as frequency regulation), an hourly basis (intermittency), and on a daily, weekly, and annual basis (meeting peak demand).
