顺电体，例如NPO，中由于不存在自发极化的机制，因此观察不 到老化现象。老化速率受电容器“电压状态”的影响。元件在高温（低联系欧阳：15217057671 0755-2 9120592 QQ：2355274968 可获得免费寄样服务，随时欢迎您的来 电

低。从理论上讲，高温下的电压负荷会促进极化畴的的弛豫。当然， 如果实际温度超过了居里点，电压效应则会消失。
How To Understand Aging
Ceramic capacitors made with ferroelectric formulations display a decay of capacitance and dielectric loss with time. This phenomenon, called aging, is reversible and occurs due to the crystallographic changes of ferroelectrics with temperature.
