为了保证低泄漏电流和低介电吸收，反馈电容器应当由合适的介电材料(如聚苯乙烯、聚丙烯或聚四氟乙烯)制成。
To ensure low leakage current and low dielectric absorption, the feed back capacitor should be made of a suitable dielectric material such as poly styrene, polypropylene, or Teflon.
如第2.3.2节所述，电容器的容抗随着频率的增加而降低，这就会增加反馈电流表的增益。
As discussed in Section 2.3.2, the decreasing reactance of the capacitor with increasing frequency will increase the gain of the feedback ammeter.
