接地信号 [jiē dì xìn hào]
ground signalling
- 通过将天线建造在低导电性的地点，并且将馈线/天线的终端接地，信号被迫深入地球，使得地球本身成为一个有效的辐射单元。
By building the antenna at a location with a poor effective conductivity of the ground, and by grounding the ends of the feedline / antenna, the signal is forced deep down into the earth, making the earth itself the effective radiating element. - 摘要对小电流接地系统中可能构成虚幻接地的主要故障进行了分析，提出了在小电流接地系统中发生接地信号时鉴别真假接地的判断方法，为防止这方面的误判断提供了参与依据。
The faults that might cause "virtual ground" in the small current grounding system are analyzed, and the methods for discriminating the true ground fault when the ground signal is sent out in the small current grounding system are proposed. - 非平衡的方式中，屏蔽线也用于传输信号，这意味着连接两端都不可能真正地接地，事实上，信号电流也许就不存在。
With unbalanced interconnects, the fact that the shield carries signal current means that it cannot be truly "grounded" at both ends or there would, de facto, be no way for signal current to exist.
