然而，要使用电容器就必须明白其特性：包括电容值、额定电压值、温度系数以及泄漏电阻等。
However, to be useful, they must be characterized for capacitance value, voltage rating, temperature coefficient, and leakage resistance.
界面层的存在使介电系数、自发极化、矫顽电压、漏电流都与薄膜的厚度有关。
Dielectric constant polarization coercive voltage and leakage current have relations with the thickness of thin films because of the interface layer.
