Ion flow

原声例句
经济学人(汇总)

Strong connections, with lots of ion flow, indicated that social experiences were rewarding.

离子流多的强力连接表明社会经验是有益的。

经济学人(汇总)

Conversely, weak connections (those with little ion flow) indicated that social experiences were not triggering a reward.

相反,连接薄弱(离子流较少)表明社会经历没有触发奖励。

经济学人(汇总)

That, though, happens only when the ion flow is balanced by a flow of electrons through an external circuit between the electrodes.

然而,只有当离子流被通过电极之间外部回路的电子流平衡时,这种情况才会发生。

电流 Electric current

(重定向自Ion flow)
一缕一缕铜丝共同组成传导电流的电线。
根据安培定律,电流会产生磁场。
简图表示出常规电流的流向和电子的流向。正电荷(红线)从电源的正极移动到负极,而电子(绿线)则从负极移动到正极。

电流(英文:Current)是指一群电荷的流动 。电流的大小称为电流强度,是指单位时间内通过导线某一截面的电荷,每秒通过1库仑的电荷量称为1安培。安培是国际单位制七个基本单位之一。安培计是专门测量电流的仪器。

大自然有很多种承载电荷的载子,例如,导电体内可移动的电子、电解液内的离子、电浆内的电子和离子、强子内的夸克。这些载子的移动,形成了电流。有一些效应和电流有关,例如电流的热效应,根据安培定律,电流也会产生磁场,马达、电感和发电机都和和此效应有关。

Electric current 电流

(重定向自Ion flow)
A simple electric circuit, where current is represented by the letter i. The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's Law.
The electrons, the charge carriers in an electrical circuit, flow in the opposite direction of the conventional electric current.
The symbol for a battery in a circuit diagram.
According to Ampère's law, an electric current produces a magnetic field.

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.

The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.
