电线路通电时，周围产生一个可以影响临近线路的电磁场，随着频率的升高，其影响也越强。
When a current flows through a wire, an electromagnetic field is created which can interfere with signals on adjacent wires. As frequency increases, this effect becomes stronger.
结果表明：随着发音频率的升高，环甲肌及甲杓肌的电活动逐渐增强。
The result showed that:As the frequency increased, the activity of CT and TA was increased.
结果表明，孔径抖动引起的孔径误差随着高速数据采集系统输入信号频率的升高而增大，由此将引起系统信噪比的下降。
The jitter error brought in by the aperture jitter increases as the frequency increase of the input signal in high speed data acquisition systems, thus it degrades the system's SNR.
