不稳定电流
The flow is unsteady in current time and forecast period.
在目前和水位预报期内均为非稳定流运动.
The output current and voltage zero regulation are achieved through the close cycle control of the unsteady flow of thyristor and the pressure regulating device by means of the thyristor digit trigger composed of monolithic computers processors and by the use of PIB regulating technique.
用单片机组成晶闸管数字触发器,并结合PID调节技术,对晶闸管变流、调压装置进行闭环控制,实现输出电流、电压无差调节。
