匹配阻抗 meaning in English

matched impedance
matching impedance

Through the monitoring on the frequency performance and square - wave response performance of manganese - zinc ferrite coil with different sizes . , different ratios of winding and different matching impedances , the result shows that manganese - zinc ferrite coil with proper ratio of winding and matching impedance can effectively restrain the interference and damage which the over - voltage and large - current signals of the power system do to the on - line monitoring system
通过对不同尺寸、不同匝数比和不同匹配阻抗下的锰锌铁氧体线圈的频带性能、方波响应性能测试实验，结果表明：适当匝数比和匹配阻抗的锰锌铁氧体线圈可以有效地抑制系统过电压和大电流信号对在线监测系统干扰和破坏。
