I was in electrical engineering major, because there was no computer science.
专业是电子工程，因为当时没有计算机科学这个专业。
-
Over there, I studied for my Master's, where I got a Master's in Electrical Aerospace Engineering.
在那儿，我攻读了宇航电气工程硕士。

They're producing electrical signals in the brain they're not recording from the brain, but it's not that big of a difference.
它们只能向大脑发出信号,而不能记录反馈大脑的信号,但是这两者技术要求差别不大
-
But I can equate the amount of mechanical energy in the electron to the amount of electrical energy that was imparted through the electrodes.
但我们可以把电子中机械能量数量,和通过电极传送的,电子能量数量等同起来。

I don't know if you know how a spark plug works, but for the electrical current to fly into operation in a spark plug, the two points of contact have to be gapped.
我不知道你们是否知道,火花塞是怎样工作的，在电流通入火花塞中使它运转之前，两个接触点之间需要有空隙。
-
If you will buy stock in an electrical utility which has a guaranteed revenue stream, because no matter how bad the economy gets, a lot of people still use electricity, you don't expect it to fluctuate a lot.
如果你在有着,保障性年收入的电气供应股票投资，因为不管经济变得怎么查，人们还得用电，它不会降多少。
-
You bring somebody in the sleep lab, you put electrodes on their scalp and you see what these-- what sort of electrical activities you get in the brain.
把人叫来睡眠实验室，把电极贴在他们的头皮上,你就能看到-,他们有什么脑电活动。
-
I studied electrical engineering and computer science, graduated in 1986 from Princeton.
我的专业是电子工程,及计算机科学，1986年从普林斯顿大学毕业。
-
Now, if you're an engineer, and you use the ideal gas law to design a chemical plant or a boiler or an electrical plant, you know, a steam plant, you're going to be in big trouble.
比如说锅炉，蒸汽机,我们会遇到一个大问题：,我们设计的机器将无法运作，因为对大部分实际气体。
-
and then specialized in the aerospace industry, continuing in the electrical engineering field.
后来专攻宇航工程专业，以便继续电气工程领域的研究。
-
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
-
So, in order to have fast transmission you do that by transmitting electrical signals; that happens pretty quickly.
所以 为了使信号迅速地传播,细胞使用电信号,它速度非常快
-
We've found that stimulation, electrical stimulation deep in the brain can help patients that have Parkinson's Disease and can reduce the tremors and loss of muscle control that many patients with Parkinson's Disease use.
我们已经发现,这种脑部深层的电刺激,可以缓解帕金森氏症患者的症状,如震颤和肌肉丧失控制,许多帕金森氏症患者都使用这种疗法
-
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
-
This is a mechanism by which an electrical signal comes here, it gets translated into a chemical signal, the chemical diffuses across the gap and reinitiates a - an electrical signal in the next cell and that's one way that it happens.
这就是电信号产生的机理,电信号翻译成化学信号,化学物质扩散过突触间隙,重新激起下个细胞中的电信号,这是一种方式
-
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
-
If you put the electrodes in the right position and you measure in the right way you can detect the electrical activity of the heart and record it on a strip recorder like this one shown here, or display it on a computer.
如果将电极放置正确,并采用正确的方式检测,就能检测到心脏的电活动,并将它记录在像这样的长图记录仪上,或者显示在电脑上
-
So, when the value of the average valence electron energy lies between 11 eV and 13 eV, we have these elements that are neither fish nor fowl, and you'll see in a little bit their unique electrical properties.
所以，当平均价电子能,在11eV到13eV之间时，这些元素介于金属和非金属之间，你们将进一步,看到它们独特的电性质。
