That is we make animation file when you put the current to the coil of the field, getting established magnetic field.
即通过制作动画效果,当你将电流,输送到线圈上，形成磁场。
-
It's like electricity, you know, like the feeling of seeing that many people in the stadium
就像电流一样，那种在体育场看到超多人的感觉，
-
In an aqueous solution, he passes electric current and causes silver ions to deposit and form metallic silver.
在水溶液中，他接通电流，这得银离子,沉淀，并形成金属银。
-
We can actually see spatially all the details in the field animated as you turn the current on and off.
我们能看到,所有细节的空间动画分布,就在你打开电流和切断的时候。
-
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
-
Your computer works on wires and electricity but your brain uses tissue and tissue is extremely slow.
你的计算机依靠电线与电流而得以运行,但你的大脑应用的则是组织,而组织的反应则是相当缓慢的
-
We know that charge is equal to the integral of current times the time. And he knows the current, he knows how much time and then he weighs this.
我们知道电量等于电流,对时间的积分，他知道电流，他也知道时间，然后他测量这个。
-
This is on the basis of the integral of the current times the time.
这是根据电流对,时间的积分。
-

到达轴突末梢的电流变化,刺激了神经递质的释放
-
And he measures how much charge is required.
他也测量出了需要多少电流。
-
Because it's a gel electricity is going to move through the gel because there are ions in it the same way - for the same reason you don't drop an electrical device into the bathtub because charge moves through water that has ions in it.
由于凝胶中存在离子,电流会通过凝胶,同样--,因为同样的原因你不会把电器扔进浴缸里,因为水里也有离子,所以水可以导电
-
You turn on your lamp, it happens pretty fast because current can flow very quickly through wire or through a charged - a solution of ions.
你打开灯 灯马上就亮了,电流可以迅速通过,电线或者带电荷的--电解质的溶液
