According to the chirality of the weakcharge the origin of parity nonconservation in the weak interactions is reasonably explained.
根据弱荷的手征性，合理地解释了宇称不守恒的原因。

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。

It can charge all kinds of mobile phones directly under sunshine, it also can charge with discharging from its built-in battery in any places with weak sunshine or without sunshine.
