Because there are ions moving back and forth, there's a current that flows and there's a electrical potential that's generated.
由于离子的进进出出,就产生了电流流动,并且形成了电势差
-
The flow of information is really a flow of electrical potential and it goes in one direction only.
信息流实际上就是电势差的流动,并且流动是单向性的
-
And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.
电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。

It turns out the electrical potential or electricity that you can measure on the surface of the body reflects things that are happening deeper inside like the beating of your heart.
人们已经证明在体表测量得到的电势能,或者电信号,能够表征,像心跳这样,身体较深处的变化
-
Rather than by forming an image or a picture you put electrodes on the surface of the body and measure the electrical potential as a function of position on the body.
它并不对人进行直接的造影,而是将电极放到身体表面,通过测量该位置电势能,表征该部位的生理状态
-
Well, the mechanism that the cell uses to transmit information along itself, along this process which goes from my brain to my fingers, for example, is through an electrical signal called an action potential.
神经细胞沿突起,将信息从我的大脑传递到,手指的机制是,举例来说,是通过一种称为动作电位的电信号的作用
-
So, there's a continuum of electrical connection in the heart that allows an action potential to sweep across the surface of the heart and for the heart to beat in a coordinated fashion.
所以 心脏细胞有电偶联的连结组织,以使动作电位平稳在细胞表面传递,保证心脏的协调性跳动
-
They carry a potential, that is, if you could - if you had a tiny, tiny electrical meter, you could one put one electrode on one side of the cell membrane, on the extracellular side and one on the intracellular side and measure, you would measure a potential difference; just like a battery you would measure a potential difference.
它们带有电势,就是说,如果你能有一个足够小的电位计,可以把一个电极放在细胞膜一侧,假设放在细胞外的一侧,另一个电极放在细胞内侧并测量,你能测到一个电势差,就像电池那样能测到电势差
