Time deviation due to propagationdelay can be tolerated.
允许存在传输延迟所引起的时间漂移。
2
The timedelay and pulse width also depend on propagation distance.
脉冲时间延迟和脉冲宽度还随传输距离发生变化。
3
Continous observations of the propagationdelay variation of BPM standard time signal were carried out in real time at Wuhan Ionospheric Observatory by a digital display system.
