The population analysis proved the interaction between helium atom and V was electrovalent bond. The helium had the stronger attractive to the vanadium atom which was in lattice site.
集居数分析表明氦原子与金属钒之间的相互作用主要是离子键,其对靠近氦原子晶格位置的钒有比较强的吸引,容易形成格点位置的空位缺陷。

So let's take two cases of shielding if we're talking about, for example, the helium, a helium nucleus or a helium atom.
所以我们来对屏蔽举两个例子,如果我们在讨论氦,举例来说一个氦原子核或者氦原子。
Because protons and neutrons have roughly the same mass (and electrons have almost no mass), the helium atom should have about four times the mass of the hydrogen atom.
由于质子与中子的质量大约相等(并且电子几乎没有质量),氦原子的质量大约应是氢原子质量的四倍。
A helium atom weighs less than the four original hydrogen atoms.
一个氦原子的重量不到四个原始氢原子。
z So, this is what we find the actual z effective is for an electron in the helium atom.
所以这就是我们得到了实际有效的,对于一个氦原子的电子。
So let's take two cases of shielding if we're talking about, for example, the helium, a helium nucleus or a helium atom.
所以我们来对屏蔽举两个例子,如果我们在讨论氦,举例来说一个氦原子核或者氦原子。
All right. Let's consider now the second extreme case, or extreme case b, b for our helium atom.
好的让我们现在来考虑,一下第二种极端案例,或者极端案例。
