  • And these shapes of p orbitals probably do look familiar to you, most of you, I'm sure, have seen some sort of picture of p orbitals before.

    这些p轨道的形状你们可以能已经很熟悉了,我相信大部分人,都看过p轨道的图片。

  • Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.

    记住,我们不需要把它们一一对应,因为px和py轨道是,m等于正负1轨道的线性组合。

  • They don't care that there are other atoms and molecules around. So that's basically what you do when you take p goes to zero.

    这正是当压强无限小时,气体的行为,气体的体积无限大。

  • So the proposal that death is a matter of permanent cessation of P-functioning versus temporary, that doesn't seem like it's going to do the trick.

    所以说死亡只永久地,停止人格功能性的这个说法,也不是正确的。

  • So for example, if we think about fluorine, 1 s 2 2 s 2 2 p 5 that has an electron configuration of 1 s 2, 2 s 2, 2 p 5, so all we would need to do is add one more electron to get the same configuration as for neon.

  • Normally I couldn't do that Vdp because this term would have p dV plus V dp, but we've specified the pressure is constant, so the dp part is zero.

    一般情况下我不能这么写,因为这一项会包含pdV和,但是我们已经假定压强为常数,所以包含dp的部分等于零。

  • We want to do that because we have too many variables here. We've already got dV p we'll get rid of p as an additional variable and replace it with V which is already in here.

    我们之所以要那么做,是因为这儿有太多变量了,我们已经有了dV,我们要把,作为额外的变量消去,用已存在的V代换它。

  • So it might look like here, if you don't understand about p orbitals, which I know all you do, but if someone else was just looking and seeing, it kind of looks like there's two bonds here.

    这里看起来有点像,如果你们不知道p轨道的话,我知道你们都知道,但如果另外有个人看到这个,这看起来有点像两个键。

  • I'm sure you're thinking well, what do we do in the case of p orbitals, and, in fact, we can do the same thing.

    我相信你们也会想,如果有p轨道会怎样,实际上,我们也可以一样做。

    麻省理工公开课 - 化学原理课程节选

  • And the significant difference between s orbitals and p orbitals that comes from the fact that we do have angular momentum here in these p orbitals, is that p orbital wave functions do, in fact, have theta and phi dependence.

    轨道和p轨道的,不同之处在于,在p轨道,波函数,随theta和phi变化。

  • Keep in mind we do have this p orbital here and it's coming right out at us. And this p orbital is here, but it's empty, it doesn't have any electrons in it, that's why we don't have to worry about it in terms of getting our electrons as far away from each other as possible.

    他们程120度角互相远离,这样它们离得最远,记住我们这里确实有个p轨道,它朝向我们,这里有个p轨道,但它是空的,里面没有电子,这就是为什么我们在考虑。
