where we could have dinner and it was free of charge, that kind of thing.
我们可以在那里吃晚餐，而且完全免费，诸如此类的。
-
Next time maybe we'll charge it up before class.
下一次或许我们,会在课前把它充上电。
-
So, an energy deficit, accelerating charge, the accelerating negative charge, because it's the negatives that are orbiting the positive center.
能量的损失，加速电荷，加速的负电荷，因为这是负电荷,围绕在正电荷中心的周围。
-
That means that it's harder to make a market for it, so the dealer wants to charge more.
这意味着,这样的品种市场很小,所以中间商要收取更多的费用
-
It's proportional to the electric charge of either object.
而与物体的带电量成比例
-
I don't mean they dig in the ground, but they supervise it; they think about it. They are like people who are in charge of a plantation, their own plantation,I mean.
他们亲自开垦土地,但是他们亲自监督,他们出谋划策,他们就像是,自己种植园的负责人
-
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

It's your own decision to eat Okay. The man is in charge of his dietary destiny.

-
ve something like, recent study shows of 30,000 Canadians have gone for other countries for health treatments, even though they got it free of charge in Canada, ve get to pay for it somewhere else, and they go.
有大约，You’,最近调查显示是3万加拿大人,去别的国家,寻求医疗，即使在加拿大有免费的，他们在别处得付费，and，they’,他们还是选择出去。
-
So, if we compare the sulfur to the oxygen, the oxygen it turns out is more electronegative and that is what holds the negative charge in this molecule.
因此，如果我们来比一下硫和氧，氧应该有更高的电负性,而在这个分子中它确实有负的电荷。
-
And let's say our second electron now is really far away, such that it's actually not going to shield any of the nuclear charge at all from that first electron.
距离原子核非常非常近,我们说第二个电子处于非常远的位置,这样它不会对第一个电子,感受到的来自原子核的电荷量有任何屏蔽作用,我们最后要说的是。
-
It bears a negative charge and the value of minus 1.6 times 10 to the 19 coulombs.
电子是带负电荷的，并且,负电的值为1。6乘以10到19，库伦。
-
And what if I took a unit charge and I multiplied it times unit voltage, one volt?
如果我取个元负荷,让它乘上个电压单位，一伏特？
-
It turns out, and we're going to get the idea of shielding, so it's not going to actually +18 feel that full plus 18, but it'll feel a whole lot more than it will just feel in terms of a hydrogen atom where we only have a nuclear charge of one.
结果是我们会有,屏蔽的想法,所以它不会是完整的，但是它会比原子核电荷量,吸引力要大很多,只有1的氢原子的。
-
So, if I've got positive charge uniformly distributed, look at the choice. It's a brilliant experiment.
所以如果按照正电荷是均匀分布的假设来说，就会是这样的，这是一个聪明的实验。
-
Most companies do splits because that might close the-- you might have been thinking about investing in Google but you could still--you could just say, I want to buy ten shares or five shares and the broker will do it for you, but they might charge a higher commission.
大部分公司会分割,因为这样会关闭...,比如你想投资谷歌,但是你可以说,我想买十股,或者五股,经纪人会照办,但是会索取更高的佣金
-
If you bring a plus charge near a plus charge, if my body m, has a plus charge and another plus charge is there, it'll feel a force due to that.
如果让两个正电荷靠近,如果一个物体 m 带正电荷,在这里有另一个正电荷,它就会感受到力的作用
-
The first is this the z effective, or how much charge is actually in the nucleus that's felt, Z or the I guess we would say the z, how much the charge is on the nucleus that holds it close together.
第一个是有效核电量，或者说实际感受到的核电荷量，又或者我想我可以说就是，使它们保持在一起的,原子核的电荷量。
-
So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.
那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。
-
It still has positive charge, and there is nothing saying another chloride could not stick to it.
它仍然具有正电荷，不能说明另外一个氯,不能固定在上面。
-
We'll get to oxidation number in the second half of this course, but it's not in any way the same idea as formal charge.
我们会在课程的后半部分讲到氧化数，但它和形式电荷完全不是同一个概念。
-
