Whether that result is positive or if is a flat result or something in between - something that we're not quite sure what it is - it is the first ever anti-retroviral containing product.

And, we're going to look at what happens as the chloride ion moves from infinity in towards the positive ion.

and you know, we're all trying to make the... trying to interact with the audience in a positive way,
而且你知道，我们都试着以一种积极的方式与观众互动，

"We're looking for concrete steps. And we take it as a positive sign that they've agreed in principle to take a couple of significant steps the opening of the Qom facility, and then working out a procedure for having their low-enriched uranium re-processed in another country.

It turns out that it's going to be a little bit different when we're talking about positive ions here.
结果是当我们讨论阳离子时,有一些不同。
-
If it is, in fact, positive, then we're going to go in here, but now notice what we're doing here.
如果这个数实际上是个正数，那么我们就到,这里面来，但是请注意我们在这做了什么。
-
The suggestion there is that one of the ways that we're God's servants and representatives on earth is to to a positive engagement of diversity.
这暗示我们，我们有一种方式,担当上帝在地球上的仆人和代表,那就是，积极地融合差异。
-
10 Even if your content subtotal was negative ten, that doesn't mean you're not better off alive, because negative ten plus the extra hundred points for the mere fact that you're alive is still going to give you a positive total, 90 plus 90.
就算你的生活内容部分总和是，那也不意味着你活得不够好，因为-10加上额外的100分说明了,你活着得到的总和仍然是正数，超过。
-
They're going to move from a negative pole to a positive pole, so they're going to move through this gel.
它们会从负极移向正极,会通过这块凝胶板
-
And we're going to have q2 prime, and we're going to draw the arrows in the positive direction in these cases.
还有q2一撇，在这个例子中,我们把箭头朝正方向。
-
The banker knows everybody in the community and when you're playing golf with the banker, it may go beyond just collecting information; the banker might have positive suggestions.
银行家认识圈里的所有人,当你在和他一起打高尔夫的时候,不仅仅能获取资讯,还可能会从银行家那获得建设性的建议
-
So, what we're looking at here is the force when we have two charged particles, one positive one negative -- here, the nucleus and an electron.
我们现在研究的是,一正一负俩个带电粒子之间的,作用力-在这里。
-
The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.
概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。
-
So, shielding happens when you have more than one electron in an atom, and the reason that it's happening is because you're actually canceling out some of that positive charge from the nucleus or that attractive force with a repulsive force between two electrons.
所以当你们在原子中有多于一个电子,屏蔽就会发生，它之所以会发生的原因是,你们实际上抵消了,一些来自原子核的正电荷,或者来自吸引力,在两个电子之间。
-
.. Because we also have to add in, if we accept a valuable container theory, we also have to add in some extra positive points to take account of the fact that, well, at least you're alive or have the life or a person-- or whatever it is that you think is valuable in and of itself.
因为我们还要添加，如果我们接受有价值容器理论的话，我们还要添加一些额外的正数,你要考虑，你至少活着或者拥有人的生命-,或任何你觉得它本身有价值的东西。
-
But we'll go over that, particularly some exceptions, when we're filling in electron configurations, and how we would go about doing that for positive ions, which follow a little bit of a different procedure.
但是我们将会重温它们，特别是一个特例，当我们填充一个电子构型，而且我们会如何着手,处理阳离子，它遵从一些别的不同的过程。
-
You're saying that being alive per se has some positive value.
你说活着本身是有些正面价值的。
-
And when we're looking at the probability density graphs, it doesn't make a difference, it's okay, It has no meaning for our actual plot there, because we're squaring it, so it doesn't matter whether it's negative or positive, all that matters is the magnitude.
它的概率密度图的时候,两者没什么区别，这是可以的，它对我们画这个图，没有什么意义,因为我们是取平方，所以它的正负，无所谓，只和幅值有关，但当我们说到。
-
Now, notice that since we are adding extra positive facts, extra positive points, for the fact that you're alive, even if the contents subtotal is negative, the grand total could still be positive.
由于我们添加了额外的积极事物，额外的正数，因为你活着，就算生活内容的部分总和是负数，但它的总和可能仍然是正数。
-
Because we've got one q1 and then we're adding q2 over q1 to it, but we've got negative q2 is a positive number.
这是因为这里有个,然后加上了q2除以，但是我们知道负的q2是个正数。
-
And it turns out that when you constructively have two p orbitals interfere, and when I say constructively, I mean they're both either positive or they're both the negative lobes, that's when you got bonding.
当两个ｐ轨道,相长干涉时，我说的相干相长，意思就是说它们要么都是,正的叶瓣要么都是负的叶瓣，这时就能成键。
-
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。
-
So the correct answer for titanium plus two Ar3d2 is going to be argon 3 d 2, whereas if we did not rearrange our order here 4s2 we might have been tempted to write as 4 s 2 so keep that in mind when you're doing the positive ions of corresponding atoms.
所以正2价钛离子,的正确答案是，然而如果我们不重新安排顺序,我们可能会写出2,所以请记住,它当你们在解关于原子,的正离子的时候。
-
putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.
把这些放在一起，你们再看一下题目,大家100%都能选对，我们唯一的选择就是这个，它不是负数，它是正的，因为我们说的，是要,把电子激发出来,需要提供的能量。
-
Then we go negative and we go through zero again, which correlates to the second area of zero, that shows up also in our probability density plot, and then we're positive again 0 and approach zero as we go to infinity for r.
并且再次经过,这和，第二块等于0的区域相关联,这也在,我们的概率密度图里反映出来了，然后它又成了正的,并且当r趋于无穷时它趋于。
-
sa So we have 1 s a, and we're drawing this as having a positive amplitude, but since we have destructive interference we're going to draw 1 s b as having the opposite sign, so we have a plus and a minus in terms of signs.
我们有，我们把这画成一个正的振幅，但因为我们是相消干涉,我们把1sb画成相反的符号，所以我们有一正一负两个符号。
