In Helen's first experience with the ocean, she was caught by a wave and pulled under the water.

He came up with the relationship that nu bar, which is called wave number --He found the reciprocal.
他也提出了它们与波数的关系，波数是波长的倒数。
-
We need to come up with an experiment in which the electron is going to be forced to behave as a wave.
我们得想出个实验,在这个实验中电子必须,要表现得像波一样。

The tariff has spurred a wave of anti-American Internet postings in China, with calls for Beijing to stop buying U.S.bonds.

We started talking about these on Wednesday, and what we're going to start with is considering specifically the wave functions for multi-electron atoms.
我们从周三开始讨论这些，而且我们将要以特别地考虑,多电子原子的波函数,为开始。

The revelation triggered a wave of condemnation on the House floor, with Republicans j oining Democrats in calls to speed passage of new sanctions legislation.

If you hook a radio wave up with a radio, you can tell the radio wave was there because what the radio is doing?
如果你用收音机检测无线电波，你可以知道无线电波在那,因为收音机在干什么？
-
Keep them up. Wave them in the air with a bit of motion.
先别放下手,再举一小会
-
So when you operate on the wave function, what you end up with is getting the binding energy of the electron, and the wave function back out.
所以当你将它作用于波函数时，你得到的是电子的结合能,和后面的波函数。
-
So, having other particles around that have the same energy that you could technically add up if you were adding them up like a wave, you can't do the same thing with particles, they're all separate.
所以，如果它们是波,你可以把其他的,拥有相同能量的粒子加起来，但是你不能把这些粒子加起来，因为它们是分离的。
-
So instead, these would be canceling out wave functions between the two, so we would end up with a nodal plane down the center.
相反，两者之间的,波函数会相互抵消，所以我们在中间会得到一个节面。
-
It's the same thing with molecules a molecular wave function just means a molecular orbital.
这对于分子也是一样,分子波函数就意味着分子轨道。
-
So I would choose something that have a wave lines off You wouldn't measure the dimension of a human hair with a yardstick, so I need something on this order.
所以我会选些东西,你将不会用一个码尺去量,人的头发有多大，所以我需要一些这个级数上的东西。
-
Ever since this was first proposed, there has never been any observations that do not coincide with the idea, that did not match the fact that the probability density is equal to the wave function squared.
从未有，任何观测，与它相抵触,从没有过，波函数的平方不等于,概率密度的情况，关于马克思，波恩。
-
So on Friday, we'll start with talking about the wave functions for the multi-electron atoms.
在周五，我们要开始讨论,多电子原子的波函数。
-
So, that's having to do with the actual wave function.
正的波函数有关,以后它会更加有关系。
-
So again, if we think of a graph of the wave function, we had the wave function is at its highest amplitude when it's lined up with the nucleus, and then as we got further away from the nucleus, the amplitude of the wave function ends up tapering off until it never hits zero exactly, but it goes down very low.
同样，如果我们想象一幅波函数的图，波函数在原子核的位置上,有着最高的振幅，随着与原子核距离变远，波函数振幅逐渐变小直到,它永远不会到零，但它会变得很小。
-
Similarly, with the second hydrogen atom, we've got the nucleus in the middle, and the 1 s b wave function around it.
类似的，在第二个氢原子里面，我们在中间有原子核，周围有1sb波函数。
-
So they're the same shape, this is the shape of the orbital or the shape of the wave function, and we can call this either 2 p x a being combined with 2 p x b, or we could say since it's the same shape, it's 2 p y a being combined with 2 p y b.
它们形状是一样的，这是轨道的形状或者波函数的形状，我们叫它2pxa和2pxb结合，或者我们说因为它们的形状是一样的，它是2pya和2pyb结合。
