So we don't have any trouble with negative times.
所以此处负根对我们不构成干扰
And it turns out the second solution, with negative energy, was when the theory is telling you, hey, there are particles and there are anti-particles, and the negative energy when properly interpreted will describe anti-particles.
结果,后来证明,第二个根,也就是能量为负的那个根,正是理论的关键,世界上既有粒子,也有反粒子,负能量就是用来解释反粒子的
Mr.Medvedev said he wants to make special mention that potential negative consequences from decisions (to go through with the NATO exercises) will completely and thoroughly be the responsibility of officials who adopt them.

So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.

So when I get back, I associate the flag with a very negative, that was the yonder side of American democracy.
之后,我就总会把国旗和负面的东西联系在一起,那也是美国民主的另一面。
So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.
那么,如果我们考虑的是第二个例子,也就是氰离子,那么现在我们讨论的是一个净电荷量为负一的分子。
There is a blunting in this activation, and this blunting is correlated with this schizophrenic self-reported lack of desire negative symptorms.
这部分的活动被关闭了,而这种关闭活动的结果和精神分裂症患者,缺少欲望症状的报告相符。
On the positive side,when we cultivate these things, it also helps us deal much better with the negative when dead arises.
在积极的一方,当我们注重培养这些情感因素,就会助于我们更好地处理,消极因素。
I want to conclude with problems, which may sound kind of negative but this is--I don't shrink from negativism.
我想以保险业的缺陷作为本课总结,它可能听起来有点否定意味,但这是,我并不讨厌否定
But it's also possible-- actually compatible with accepting that fact-- there are two additional possibilities, that there might be some negative interaction effects.
但同样也有可能-,事实上与接受这个事实一致-,有另外两种可能性,可能会产生负面的相互影响。
But in the real world when dealing with humans, but even when dealing with animals, we don't actually always use primary reinforcers or negative reinforcers.
但当我们在现实中训练人类,甚至是训练动物时,我们实际上并不总是用到初级强化物,或是负强化物。
All the energies are negative because it is a bound system. I start up here with n equals one.
所有能量级都是负数,因为它是一个束缚系统,在这里我从n等于1讲起。
This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.
所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。
Another way to say that it's going to be less, so you don't get confused with that the fact this is in the numerator here, there is that negative sign so it's less energy but it's a bigger negative number that gives us that less energy there.
另一个方式去说它将会变得很低实用,你们不用在这里的计算器的事实感到迷惑,这里有一个负号实用,它是更少的能量,但它是一个更大的数字,这里了它给了我们更少的能量。
You've got a positive charge here with a negative charge around it.
正电荷在这儿,负电荷在周围。
So we end up with a formal charge on carbon of negative 1.
因此最终我们得到碳的形式电荷量是负一。
They're not bad, bad, they're not nightmares, but most dreams are from a scale of one to ten with five and a half in the middle they're on the negative side.
说它们不好,并不是说它们是噩梦,如果用1到10来评分,5。5为中间分值,大部份梦都是在5。5分以下。
On the other hand, if the balance from here on out would've been negative, then it's good for me that I died now instead of being kept alive with a life not worth living.
另一方面,如果从现在开始计算其结果是负数,那么我现在死去就是好事,因为我不用不值地活着。
The finding is that if your race or your group has a negative stereotype associated with it in any particular domain, being reminded of it serves as a stereotype threat and hence damages your performance in all sorts of domains.
他们发现如果你的种族或群体,跟一个消极的刻板印象有关,随便在什么领域上,如果别人在你面前提前,就足以构成刻板印象威胁,从而影响你在这个领域上的表现。
And shielding is a little bit of a misnomer because it's not actually that's the electron's blocking the charge from another electron, it's more like you're canceling out a positive attractive force with a negative repulsive force.
屏蔽有一点点用词不当,因为它事实上不是,电子阻挡了来自另一个电子的电荷,它更像你在用一个负排斥力,抵消一个正吸引力,但是屏蔽是考虑这个问题,的很好的方式。
They also help us deal with the negative.
积极心理学还帮助我们处理消极情绪。
So what we are doing: we cultivate the positive; we are strengthening our,metaphorically speaking, " psychological "engine"; and we are better able to deal with the negative to zero, not to mention the fact that we are also able to become happier.
所以我们在做的是,培养积极性;,按那个比喻来说,我们正在增强,心理“引擎;,我们能够更好将负值转化为零,更别说还能变得更快乐。
And since we have two bars that are together like this, once they're both loaded up with electrons there's going to be negative charges that repel, so the electrons will want to get as far away as possible, and they're on their slow way to doing that, to getting as far away from each other as possible.
因为我们有两个棒像这样在一起,一旦它们加载了电子,就会因为有负电荷而排斥,所以这些电子就会,互相离开的尽可能远,它们的这个过程很慢,离开的尽可能远。
Convention, OK, this negative sign is just a pure convention. You just got to use it all the time. If you use an old textbook, written when I was taking thermodynamics, they have the opposite convention, and it's very confusing. But now we've all agreed on this convention, and work is going to be with the negative sign here.
系统对外界做功的符号为负,这就是我们,在本课中的规定,纯粹出于统一符号的需要,有些教科书中,可能会使用相反的符号规定,注意不要混淆了,这门课上,我们将一直使用。
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。
And it turns out that if we have a, for example, for s, a very large z effective or larger z effective than for 2 p, and we plug in a large value here in the numerator, that means we're going to end up with a very large negative number.
结果是如果我们有一个,举例来说对于s一个很大的有效电荷量或者,比2p大的有效电荷量,并且我们将一个较大的值代入计算器,那意味着我们最后会得到,一个非常大的负数。
