这两种离子在电路中向相反方向流动。
利用相反的电荷，电极就会复位，进而断开电路。
Apply the opposite charge and the electrode flips back, breaking the circuit.
当时渔船底部进水，不断上升的水位使电路系统短路，巨大的船体开始转向相反的方向。
The ship flooded from the bottom up, and when the rising water shorted out the electrical system, the massive boat shifted into reverse.
这样就会接通电路，打开晶体管。利用相反的电荷，电极就会复位，进而断开电路。
This closes the circuit and turns the transistor on. Apply the opposite charge and the electrode flips back, breaking the circuit.
相反定时电路使用固定电容器和可变电阻如果有必要更改的时间期限。
Instead timing circuits use a fixed capacitor and a variable resistor if it is necessary to vary the time period.
相反，集成电路能够将多电子元件功能集中到一块芯片上。
By contrast, integrated circuits combine the functions of multiple electronic components on one chip.
在极性电路中，空号脉冲促使环路电流向传号脉冲相反的方向流动。
In a polar circuit it causes the loop current to flow in a direction opposite to that for a mark impulse.
图示电路的输出等于两个输入电压的乘积除以10，相位相反。
The circuit as shown gives an inverting output whose magnitude is equal to one-tenth the product of the two analog inputs.
相反，如果其他一些电压或电路中的电流通过一个理想电流源的电流决定，它被称为从属或控制的电流源。
Conversely, if the current through an ideal current source is determined by some other voltage or current in a circuit, it is called a dependent or controlled current source.
电路板相反两侧上的走线必须彼此垂直，这样有助于减小电路板上的馈通效应。
Traces on opposite sides of the board must run at right angles to each other. This reduces the effects of feedthrough on the board.
因为两臂的直流电路相等而方向相反，所以在变压器铁心中有效直流磁通是互相抵消的，所以不再需要巨大的直流元件。
Since the DC current on each side is the same, the effective DC in the transformer core is cancelled, so there is no need to provide for a large DC component.
