• May Rihani,from the U.N.Girl's Education Initiative's Global Advisory Committee, gave an unlikely example from a "life skills" curriculum being used in Mali.

  • But it grows pretty rapidly, as n goes up, and I'm going to show you an example in a second.

    解决问题需要的时间会急剧增长,一会儿我会让大家看个例子的,我想大家注意的还是。

  • So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.

    比如,在这下面我写的是氮分子2,而这个是氢分子,但我在上面把这些分子的形式改写了,大家可以看到,这是一个氢与氢之间的单键,含一个氮与氮之间的三键。

  • For example,in most sub-Saharan African countries, the U.N.Children's Fund says more than half the deliveries take place at home, with no skilled birth attendant present.

  • So, for example, let's look at thiocyanate ion, we have c s and n.

    比如,让我们来看一下硫氰酸根离子,我们有碳,硫和氮。

  • Mitchell said he is not discouraged about his mission's recent setbacks, including acrimonious exchanges over a recent U.N.report alleging possible war crimes in last year's Gaza conflict, citing the example of his successful Northern Ireland peace efforts in the 1990s.

  • So, let's, for example, look at nitrogen. So n 2, we can do the chart here in green, so it's the green dotted line, and what we see is that we have now defined this energy as where the 2 nitrogen atoms are separated.

    那么,让我们举个例子,看一下氮,那么氮分子,我们可以把它用绿色曲线画在这,这是绿色的虚线,可以看到,我们已经定义为零点能,当两个氮原子分离时。

  • We're getting further away from the nucleus because we're jumping, for example, from the n equals 2 to the n equals 3 shell, or from the n equals 3 to the n equals 4 shell.

    我们将会离原子核越来越远,因为我们在跃迁,比如从,n,等于,2,的壳层到n等于,3,的壳层,或者从,n,等于,3,的壳层到n等于,4,的壳层。

  • So, for example, if we're talking about the n equals 2 state, all of these four orbital descriptions are going to have the same energy.

    例如,当我们说n等于2的态,所有这四个轨道的能量,都是相同的。

  • All right, I want to do one more at homonuclear example here, and this is n 2.

    好的,我想要再讲一个同核的例子,这就是N2。

  • So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.

    最后我们要讲的,这个例子,是n等于2时,等于1,we,can,have,2,,1,for,l,而m等于。

  • So, for example, we could talk about the n equals 2 state, so that's this state here, and it's also what we could call the first excited state. So we have the ground state, and if we excite an electron into the next closest state, we're at the first excited state, or the n equals 2 state.

    例如,我们可以考虑n等于2的状态,它在这里,它也被称作是第一激发态,我们有基态,如果我们把一个电子,激发到它最近邻的态,那就是第一激发态,或者n等于2的态。

  • So, if, for example, we were looking at a hydrogen atom in the case where we have the n equals 1 state, so the electron is in that ground state, the ionization energy, it makes sense, is going to be the difference between the ground state and the energy it takes to be a free electron.

    电离氢原子所需要的能量,如果我们看n等于1的情况,电子在基态,那电离能,很合理的就是基态,和自由电子态的能量差。
