二极管是一种只允许电流单向流动的元件。
A diode is a device which only allows current to flow in one direction.
电网和电动车之间的电流不一定是单向的。
The flow of energy between the grid and electric cars need not be one-way.
LED是单向导电的发光体，如果有反向电流，则称为漏电，漏电电流大的济南发光字，寿命短，价格低。
LED is a single direction of the light-emitting body, if there is a reverse current, then known as the leakage, the leakage current of Ji 'nan light emitting, short life, low price.
当电池放电时，锂离子和电子将自发地做单向运动，从而产生电流释放能量。
When the battery is discharging, both ions and electrons travel spontaneously in one direction, creating a current and releasing energy.
由于负向电流可以腐蚀削减铸层表面微观突起的生长高度，因此周期换向脉冲电流微电铸与单向正脉冲电流微电铸相比更易获得较好的铸层均匀性。
Because the height of micro tips on cathode surface can be eroded by the negative current, surface finishing is better in the micro-electroforming by periodic reverse pulse current than pulse current.
