We're going to be looking at the solutions to the Schrodinger equation for a hydrogen atom, and specifically we'll be looking at the binding energy of the electron to the nucleus.

x It says, take the name x and create a binding for that name to the value of the sub-expression and in fact to do this, to stress a point, let's do that.
它的意思是，创建了一个名字,然后创建了对于这个名字,和子表达式的值的绑定,实际上这么做，我们是为了，要强调一个点，让我们来说说这个点。

Some people want to have these to be many and for them to be very binding, others want them to be very few and not very binding, and that's an argument one can get into.
有些人认为惯例更多一些,更有约束力一些,而有些人却认为惯例的限制少一些,这是争论所在
-
"What we hear is that the kind of legally binding agreement that we,for instance, did inside the European Union, will probably not be possible since some of the countries like the United States say we do not have the support in our congress to make a ratification on an international agreement,".

So, for example, in a hydrogen atom, if you take the binding energy, the negative of that is going to be how much energy you have to put in to ionize the hydrogen atom.
例如在氢原子里面,如果你取一个结合能,它的负数就是。
-
We looked at the wave functions, we know the other part of solving the Schrodinger equation is to solve for the binding energy of electrons to the nucleus, so let's take a look at those.
我们看过波函数，我们知道解,薛定谔方程的其他部分,就是解对于原子核的电子结合能，所以我们来看一看。
-
The advantage of this is that now you have four binding sites for antigen instead of just two.
这样的好处是一个抗体上,有四个抗原结合位点而不仅仅是两个
-
So I said that this technique was used to experimentally determine what the different binding energies or the different ionization energies are for the different states in a multielectron atom.
我说过，这项技术被用来,在实验上确定多电子原子的,各个不同态相应的束缚能,或者电离能。
-
There's a region up here called the antigen binding region and those-- and there's two copies of that region and it's responsible for antigen binding.
在图片上部有个区域,被称作抗原结合区,而这些,而这里有两个抗原结合区,主要负责与抗原结合
-
And we can look at precisely why that is by looking at the equations for the energy levels for a hydrogen atom versus the multi-electron atom. So, for a hydrogen atom, and actually for any one electron atom at all, this is our energy or our binding energy.
而且我们可以精确地看看,为什么是这样的,通过看对于氢原子和,多电子原子能级的方程所以对于氢原子，事实上对于任何一个电子，这是我们的能量或者我们的结合能。
-
Don't worry about how they work in the immune system, but what if you could manufacture antibodies then you could make a chemical, an antibody, that is capable of binding to a specific other chemical and you could use that for things.
别管它们在免疫系统内是怎么工作的,只要考虑能不能制造抗体,那么假设你能制造这种化学物质 抗体,抗体又能够同其他特别的化学物质结合,你就可以让抗体为我所用
-
Yeah, I've still got a binding for z and I'm giving it the same test, but notice now I've got the two same commands but they have different indentation.
对，我还是对z进行了绑定,我还是要对它进行同样的测试，但是请注意现在我有了两个同样的命令,但是它们有不同的缩进。
-
This e term here is the energy, or in our case when we talk about an electron in a hydrogen atom, for example, the binding energy of that electron to the nucleus.
这里的“E“是指能量，或者在我们谈论一个,氢原子的电子时，举例来说，是电子对于原子核的结合能。
-
They also have binding sites for antigen, but they are sort of two IgG type molecules bound together by another peptide chain.
同样IgA抗体表面也有与抗原结合位点,但它们就像两个IgG型分子,通过肽链相互连接
-
So we have the operationon the wave function in terms of r, theta, and phi and remember this e is just our binding energy for the electron, and we get back out this wave function.
我们用r，θ，φ来表示,将算符作用于波函数,而且记住e仅仅是电子结合能，然后后面加上波函数。
