Yet it can become less effective as the disease progresses.

So what we're going to see is less shielding, which means that it will actually feel a higher z effective.

那么我们将会看到更少的屏蔽，这意味着将会感受到更大的有效核电量。

The z effective is lower, so we have to put less energy in to get an ion out.

它的有效核电量更低，所以我们只需要更少的能量就能打出一个离子。

It is also more effective and less costly than the drugs traditionally used.

They're less shielded because they're closer to the nucleus, they feel a greater z effective.

它们受到少的屏蔽,因为它们离原子核更近，它们感觉到一个更大的有效电荷量。

"Now if that GM potato is effective and works then the environmental impact will be substantially less because the chemicals are not being used and there will be less fossil fuel use."

VOA: standard.2009.10.21

And what we're actually talking about again is the zeffective. So that z effective felt by the 2 p is going to be less than the z effective felt by the 2 s.

我们实际上所谈论的,所以被2p感觉到的,的有效电荷量,有效电荷量小于2s感觉到。

We know that it has to be equal to less than 2, because even if we had absolutely no shielding at 2 all, the highest z effective we could have is 2, so it makes perfect sense that we have a z effective that falls somewhere in the middle of those two.

我们知道它必须小于，因为即使完全没有一点屏蔽,最高的有效的z是，所以我们得到的有效电荷量处于,两者之间就非常讲得通了,让我们来看看另一个例子。
