I would guess a wave-function and then vary its parameters until I found the lowest energy solution.

我会任意猜测一个基态波函数，通过更改其参数找出能量最低的量子态。

The dam has recorded its lowest energy production levels since it began full operation in 2005.

自2005年开始全面运行以来，伊泰普大坝的发电量达到了历史最低水平。

Infrared light has lower energy than red light, microwaves lower than that, and radio waves have the lowest energy.

红外线比红光能量低，微波比红外线能量低，无线电波的能量最低。

So the first electron wants to go into the lowest energy state.

所以第一个电子想要进入最低能态。

Every orbital can contain, and indeed is at its lowest energy when it contains, 2 electrons.

每个轨道都可以包含 2 个电子， 并且当它包含时确实处于最低能量。

And then the first two, or the electrons in the lowest energy state, will be 1s2.

然后前两个，或处于最低能态的电子，将是 1s2。

So you might say, oh, the lowest energy state is this magenta inner sphere that I just drew.

所以你可能会说，哦，最低能量状态是我刚刚画的这个洋红色内球。

They're at their lowest energy state when they're lining up together, positive to negative, into a kind of liquid crystal.

当它们排列在一起时， 它们处于最低能量状态，从正到负，形成一种液晶。

And the general principle, remember, is that the electrons fill up the orbital from lowest energy orbital to higher energy orbital.

请记住，一般原则是电子从最低能量轨道到较高能量轨道填满轨道。

Well, if a molecule is going to be at its lowest energy state by forming a double bond, it has a nice simple solution.

好吧， 如果一个分子要通过形成双键处于最低能量状态，它有一个很好的简单解决方案。

And then we, in the last video, we said, OK, the electrons fill up the orbitals from lowest energy state to high energy state.

然后我们在上一个视频中说，好吧，电子从最低能态到高能态填满了轨道。

You can barely see it there, but it's a sphere around the nucleus, and that's the lowest energy state that an electron can be in.

你在那里几乎看不到它，但它是一个围绕原子核的球体，这是电子可以处于的最低能量状态。

If I'm playing Tetris-- well I don't know if Tetris is the thing-- but if I'm stacking cubes, I lay out cubes from low energy, if this is the floor, I put the first cube at the lowest energy state.

如果我在玩俄罗斯方块——好吧， 我不知道俄罗斯方块是不是这个东西——但如果我在堆叠立方体，我会从低能量中放置立方体， 如果这是地板， 我会把第一个立方体放在最低能量状态。
