Conduction emission is an electromagnetic emission transmitted on power or signal lines and a primary form of electromagnetic interference at low frequencies.

传导发射是沿电源线或信号线传输的电磁发射，在低频范围内，传导发射是电磁干扰的主要形式。

This charge transfer is due to the mechanical release or closure of the contacts, the contact-to-coil capacitance, and the stray capacitance between signal and relay drive lines.

这种电荷转移是由于触点的机械释放或闭合、“触点-线圈”电容以及信号和继电器驱动线路之间的寄生电容引起的。

Even so, there are a great many absorption lines of other sorts that can lead to confusion, with different lines potentially masking the signal depending on whether Mars is coming or going.

即使是这样，还需要有大量的其它各类能够导致混浊的吸收光线，并且是能够潜在地屏蔽因火星的移动而产生的信号。

It's like 'inverting' the signal on odd lines, or shifting it in time by 180 degrees of the color waveform frequency.

Power companies and networking startups have spent years touting a technology called broadband-over-power lines, or BPL. In those systems, the utility sends a data signal across existing wires at a much higher frequency than electricity, so the two signals don't interfere.
