The displacement current mechanism is operative only for capacitors under reverse bias or very weak forward bias conditions which maintain a space-charge layer .
位移电流的机理只对反向偏压或要维持空间电荷层所需要的非常弱的正向偏压条件下的电容器才有用。

Owing to the complexity in bias tire structure and material properties, it is both economical and exact to model the tire by using layer elements and solid elements.
由于斜交轮胎复杂的几何结构和材料特性，选用层单元和体单元的组合可以既经济又准确地对轮胎进行模拟。
