An external circuit provides a path for the electrons to return to the p-type material, producing an electric current along the way that continues as long as light strikes the solar cell.

此时接上一条外线电路，电子便通过线路流动到p层。只要光束持续地撞击太阳能电池，就会有持续的电流。

By means of Lagrange multiplier method, this method distributes the slack to the operator nodes in the data path, thus, efficiently reduces the energy consumption of design circuit.

应用拉格朗日乘数法，将空闲时间分布到数据通路的各个操作节点上，从而有效地降低了设计电路的能耗。

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground.

请勿接触任何会为通向被测电路的共用侧或电源地的电流提供通路的物体。
