The communication link for the primary 1 pilot relay system will be by means of fiber optic cable which is in the scope of New Transmission Facilities.
采用新传输设备范围内的光纤电缆来连接初级保护1引线保护系统通信。
Relay valves convert a sustained air flow from a three-way pilot valve into a momentary pulse or bleed, which shifts a control valve and then closes.
延迟阀可调节从三通控制阀到瞬间脉冲或放气阀的空气流量，放气阀或瞬间脉冲改变控制阀，然后关闭。
Second, channel estimation algorithms of two-hop OFDM cooperative communication system with single relay are discussed, which are mainly based on block pilot.
其次，讨论了两跳单中继多载波协同通信系统的信道估计的问题，主要是基于辅助块状导频的方法；
