介绍了目前电子级过氧化氢的质量标准;
The present quality specifications of semiconductor hydrogen peroxide are introduced.
采用电子级变速传送,稳定可靠、寿命长、低噪音。
Electronic variable speed transmission, stable and reliable, long life, low noise.
就像我们预期的设计为基础,这不是电子级多晶硅,但它并不遥远。
So as we expected based on the design, this is not electronic-grade poly, but it's not that far off.
And this is the energy level diagram for multi-electron atoms.
看一下能量级图表中,多电子原子的部分。
Now what I want to do is take you exactly to this place where we are right now, where we see energy levels and electron filling, but I want to start all over again and I want to use a totally different approach.
现在我想做的是带你们,到达我们现在所处的地方,我们能看到能量级和电子分布的地方,但我想重新开始,而且用一个完全不同的方法。
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。
