Instead of forcing people to install expensive charging stations in their garages, the batteries are compact enough to take with you indoors – charge wherever you like.
电池小巧且易于携带,这就使得车主不用在车库里安装昂贵的充电设备。 你想在哪充电都行。
This classic parable provides the audience with a moral that resonates with all of humanity: If you put monkeys in charge of society, don't be surprised when everything explodes.
这部经典预言式影片向观众传递了这样一种与所有人性特质产生共振的道德观:如果你让猴子来统治社会,当世界爆炸时,就别那么吃惊。
In the meantime, you can be duly impressed with how much charge you can shuffle around when you build up static.
同时,当你建立一个静电场时产生了多少电荷这一问题将给你留下深刻的印象。
So if you have some charge in the nucleus, but you also have repulsion with another electron, the net attractive charge that a given electron going to feel is actually less than that total charge in the nucleus.
所以如果在原子核中,有一些电荷但是你也有来自,另一个电子的排斥力,那么一个给定电子的,吸引电荷感觉到的事实上,小于原子核中的总电荷。
Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.
通常一开始把电离能最低的原子,放在中心位置就很好了,如果你发现电荷没有分开,那么这个结构就没问题了,但是如果你发现有很多分开的电荷,比如这种情况,有负二,正二和负一,那么你会想要说等一下,从形式电荷来看这很不好,让我去看看其它可能的选择。
