• At this point, we have no other choice but to double up before going to the next energy level, 2px so we'll put a second one in the 2 p x.

    在这点上我们没有其他选择,而只有双倍填充,在到下一个能级之前,所以我们放入第二个电子至。

  • This intuitively should make a lot of sense, because we know we're trying to minimize electron repulsions to keep things in as low an energy state as possible, so it makes sense that we would put one electron in each orbital first before we double up in any orbital.

    这个直观上讲得通,因为我们知道尝试去最小化电子排斥力,从而尽可能的保持处于一个较低的能态,所以它讲得通,在我们在同一个轨道放入两个电子之前,我们首先把电子放入每一个轨道。

  • Milton recognizes that way of thinking as a double standard, ; and he isn't satisfied with this vulgar double standard; so he comes up with a vulgar double standard of his own.

    弥尔顿认为这种思维方式有双重标准,他并不满足于低俗的双重标准;,因此他提出了一个他自己的庸俗双重标准。

  • If it goes on for ten years that means that the -it'll double in seven years, so it'd be going up like two and a half fold.

    如果按照此速度过上十年就意味着,七年内价格将会翻倍,所以价格应该会上涨到两倍半

  • The DNA molecule here has been spread apart, opening up two single stranded DNA's which have complementary base sequences because they were double stranded DNA.

    这里DNA分子被分开,形成两条单链DNA,这两条单链碱基序列互补,因为它们是由双链DNA解旋形成的

  • There's no more 2 p orbitals to put it into, so we're going to actually have to double up.

    现在并没有多余的2,p,轨道来放它,我们只能在其中一个,2,p,轨道上放上两个。

  • Remember we have to put one in each degenerate orbital before we double up on any orbital, so just keep that rule in mind that we would fill one in each p orbital before we a to the second one.

    我们必须把,每一个放入简并的轨道,我们把每一个电子放在p轨道里,所以把规则记在脑子里,我们把每一个电子放在p轨道里,在我们放入第二个电子之前。

  • px And I arbitrarily chose to put it in the 2 p x, 2pz we also could have put it in the 2 p y or the 2 p z, it doesn't matter where you double up, they're all the same energy.

    我任意地选择放入至,我们也可以把它放入2py或,它与你在哪双倍填充没有关系,它们都在相同的能级。

  • So, our two glitches we see when we go from the 2 p, or from 2 s to start filling the 2 p, and then we also get another glitch when we've half-filled the 2 p, and now we're adding and having to double up in one of those p orbitals.

    因此,我们的看到的两个小偏差,一个是在开始进入,2,p,轨道,或者说在填满,2,s,轨道之后,开始填,2,p,轨道的时候出现的,另一个则是在,2,p,轨道半满之后,开始继续加电子,使得其中一个,p,轨道上的。

  • And now we get the p orbitals, remember we want to fill up 1 orbital at a time before we double up, so we'll put one in the 2 p x, then one in the 2 p z, and then one in the 2 p y.

    我们到了p轨道,记住在双倍填充之前,我们想要每次填充至一个轨道,所以我们在2px填充一个然后2pz填充一个,然后2py填充一个。

  • Now, in your book, there's an example of plasmid where I've given you the exact sequence of nucleotides that makes up the whole double stranded DNA molecule.

  • It operates in a similar fashion to DNA polymerase in that it denatures locally or opens up the double stranded DNA, but it's different in that it creates a new polymer from the DNA template in the language of RNA, using RNA nucleotides and not DNA nucleotides.

    它的作用机制类似于DNA聚合酶,在局部使DNA双链变性,解旋,但不同的是,它合成了一个基于DNA模板的,使用RNA编码语言的新聚合物,即使用核糖核苷而非脱氧核糖核苷

  • The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.

    原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开

  • If I had a beaker sitting on the table here and it contained a million blue double stranded DNA molecules and a million red double stranded DNA molecules and I heated it up and added a little base, I'd soon have four million individual strands just floating around in the solution because I've broken up this hydrogen bonding and the DNA molecules fall apart.

    假如我这里有一个烧杯 里面,盛有一百万条蓝色DNA双链和,一百万条红色DNA双链,然后我稍微加热一下烧杯,并且加一些碱,很快我就有了四百万条DNA单链,漂浮在溶液里,因为我已经使得氢键断裂,DNA双链也随之打开
