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。

The space charge layer formed during point discharge process is not enough to prevent the leader from marching, and can not prevent the forming of upward leader, either.

人工尖端放电形成的空间电荷层既不足以阻止先导的继续推进，也不能防止产生上行先导。

OLETs rely on three layers of material, with the bottom layers carrying a charge, the middle layer (the meat in this high-tech sandwich) emitting photons when excited by the bottom, and the top layer selectively letting those photos through.

Light falling on to this layer creates an electric charge.

That charge, in turn, affects the third layer, which is made of liquid crystals.
