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。
-
The reason that there is increased electron density here is you can see that these two orbitals come together and constructively interfere.
你们可以看到两个轨道,靠在一起相长叠加,这就是为什么中间的电子态密度增加了。
-
If there are droughts, pests, other things that interfere with the growing of the food you've got problems.
如果发生旱灾,虫灾,或其他妨碍食物生长的灾害,你就有麻烦了
-
And his basic rights were seen to be absolute, for nothing must interfere with the right of each individual to defend his life, liberty, and property.
人的基本权利被视作每个个体都绝对拥有的,任何事物都无法干涉的,自卫,自由,财产的权利
-
It requires RNA processing to happen smoothly, so if you can interfere with RNA processing you can stop a gene from being expressed.
转录需要RNA的顺利加工,因此如果你能干扰RNA加工过程,你就能阻止一段基因的表达
-
If you compare the s orbital with the bottom lobe, these have a different sign so they're going to destructively interfere.
如果你们比较s轨道和下面这叶，它们正负号相反,所以它们相消干涉。
-
see people with them, and what happens here is it's supposed to be those noise cancellation headphones. All they do is they take in the ambient noise that's around it, and there's actually battery in the headphones, that then produces waves that are going to destructively interfere with that ambient noise.
我从来没有用过这个,但你会看到有人带他们,它们可以作为消噪音耳机,它们所做的就是采入,周围的随机噪声，耳机里面是，有电池的，然后它能产生和,随机噪声相干相消的声波。
-
You can see if we combine the s with the top lobe of the p, they're going to constructively interfere because they have the same sign.
你们会看到如果我们把s轨道和p轨道的上叶结合，它们是相长干涉,因为它们负号是相同的。
-
You could interfere at these later levels as well, for example, by augmenting RNA degradation.
你也能干扰一些下游的调控水平,例如,通过增强RNA的降解
-
If you can interfere with any stage in RNA processing you can stop a gene from being expressed and this is a very hot topic in molecular biology now and human therapeutics.
如果你能干扰RNA加工的任何一个阶段,你就能阻止一段基因的表达,这也是当今分子生物学,和新型疗法中非常热门的话题
-
And you could interfere with a translation by degrading messenger RNA, for example. If you had a way to specifically chew up all the RNA molecules that are responsible for making a particular protein, you could stop it from being expressed even though your cell is trying to make it.
而你就可以通过,降解其mRNA来进行干扰,再举个例子,如果你能把表达特定蛋白的RNA,统统揪出来捣毁的话,你也能阻止这段基因表达,哪怕是你的细胞在努力表达这段基因
-
The reason that we can talk about this is remember that we're talking about wave functions, we're talking about waves, so we can have constructive interference in which two different orbitals can constructively interfere, we can also have destructive interference.
我们可以这么说的原因是,记住我们说的是波函数，我们说的是波函数，所以我们可以得到相长干涉,这是两个不同轨道会相长干涉，我们也有相消干涉。
-
Strong enough to interfere with the ambitions of emperors and kings, it never was able to impose its own domination, though some of the Popes surely tried.
也无法与君主帝王的,雄心壮志相抗衡,宗教是无法统治一个国家的,一些教皇的努力也以失败告终
-
So you should remember that any time we combine 2 s orbitals, what we're going to find is if we constructively interfere those two orbitals, we're going to form a bonding orbital.
你们要记住，任何时候我们组合两个2s轨道，我们会发现,如果我们把它们相长叠加，我们会得到一个成键轨道。
