beam trace

基本解释

When exert a sine signal, the trace of electron beam on screen also changes along sine signal.
当水平方向偏转电压为正弦信号时，屏上电子的扫描轨迹也按正弦规律变化。
The conclusion is that the trace of electron beam on screen is in accordance with the voltage signal which exert on the level voltage plant.
研究结果表明，屏上电子的扫描轨迹随时间的变化规律与外加偏转电压信号的时间变化规律是一致的。
In this paper, we derive the mathematical formula of the trace unidirectionally etched with the grit beam on the surface of graphite pot for making pyrolytic graphite grid.
