In the United States, the Armed Forces Radiobiology Research Institute is looking for more-effective treatments for radiation exposure.

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。

But what you should be able to do is take a look at a list of answers for what we're saying z effective might be, and determining which ones are possible versus which ones are not possible.

但是你们应该能够做到的,是看一下这个可能的,有效电荷量的答案列表，并且确定哪些是可能的,哪些是不可能的。

The White House says it is preparing for the worst. Experts say the most effective solution involves drilling relief wells to reroute oil, a process that could take months.

So our minimum that we're going to see is that the smallest we can have for a z effective 1 is going to be equal to 1.

所以我们能够看到的,最小的有效电荷量,等于。

"I am sure that the cooperation between the countries in the field of strategic security is more effective for both Russia and the United States than any AMD , any armed forces or any military operation."

So again, when we check these, what we want to see is that our z effective falls in between the two extreme cases that we could envision for shielding.

所以当我们再一次检查这些时，我们想看到的是,有效电荷量处于两种极端案例中,这两种极端案例。

"I go to the gym," (No Transcripts) Michael Reagan says that while following a healthy diet, reading and learning new skills can help sharpen one's memory and possibly prevent or slow the advance of the illness, the most effective way to fight Alzheimer's is to volunteer and support funding for current research.

z So the main idea here is z effective is not z, so don't try to plug one in for the other, they're absolutely different quantities in any case when we're not talking about a 1 electron atom.

所以这里主要的观点是有效的z不同于，所以不要尝试将一个插入到另一个，当我们不在讨论1个电子的原子时,它们在任何情况下是绝对不同的量子数。
