另外，影响电容器音色品质的因素，常以逸散因素（Dissipation Factor, DF）和电介质吸收（Dielectric Absorption, DA）为主要讨论的对象。这两项均是电容器的耗损，DF的倒数就是Q（品质因素）。

为使电流测量时的电介质吸收影响减到最小，用来做对极小的电流测量的绝缘体，应避免施加大于数伏的电压。
To minimize the effects of dielectric absorption on current measurements, avoid applying voltages greater than a few volts to insulators being used for sensitive current measurements.
空气几无吸收任何能量，因此空气不算是电介质，本质上不会产生失真作用。
Air absorbs next to no energy, so air is hardly a dielectric at all, causing virtually no distortion.
采用光电流效应研究了CO 放电介质中的共振自吸收，测量了气体压力、组份和温度对自吸收的影响。
Using the method of OGE, the resonance self-absorption in CO discharge medium has been studied. The dependence of the self-absorption on pressure, componen and temperature has been measured.
