Vector equation A = B is actually a shorthand for two equations.
矢量方程 A = B 实际上是,两个方程的简写

So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.
接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数

And when you solved the relativistic form of the Schrodinger equation, what you end up with is that you can have two possible values for the magnetic spin quantum number.
当你们解相对论形式的,薛定谔方程，你们最后会得到两个,可能的自旋磁量子数的值。
-
And the beauty of that equation of state is that it only relies on two parameters.
范德瓦尔斯方程,先把结果写出来。
-
And we plug in our values and end up with mv squared mv^2/r-Ze^2/ over r minus Ze squared over And I am going to call this equation two.
我们最后的结果,就是,我把这称为方程式二。
-
They are going to accompany particles surely as every quadratic equation has two solutions.
他们是成对的粒子,正如每个二次方程都有两个根一样
-
I've set these two things equal to each other: I've got one equation and one unknown.
我让两个方程相等,只剩下了一个等式和一个未知数
-
If you think about what happens when we go from hydrogen to helium, now instead of one electron, we have to describe two electrons, so now we have six position variables that we need to plug into our Schrodinger equation.
如果你们考虑,当我们从氢到氦会发生些什么，现在我们不是要描述一个电子，我们将要描述两个电子，所有我们现在将有6个位置变量,需要加入至薛定谔方程。
-
So, therefore, we can rewrite our equation in two ways. One is just talking about it in terms only of energy where our kinetic energy here is going to be equal to the total energy going in -- the energy initial minus this energy of the work function here.
所以我们可以把方程,写成两种形式，一个是,只考虑能量，动能等于总的,入射能量-初始能量减去,功函数的能量，我们如果想解决,比方说，我们想知道。
-
He was trying to describe electrons, but the theory said there are two roots in the quadratic equation and the second root is mathematically as interesting as the first one.
他当时只是想去描述电子,但是数学理论告诉我们,二次方程有两个根,而第二个根在数学上和第一个根一样有趣
