The results indicate that argon shielding can reduce the nitrogen content but not influence that of oxygen in the weld metal.

结果表明，采用氩气保护使焊缝金属中的氮含量减少，而对氧含量的影响则不大；

Effective shielding can be achieved by reducing the breakdown probability of the gap between shielding wire and phase conductor.

提高避雷线保护的有效性可以通过减小避雷线—相导线间隙击穿概率来达到。

It can have a profound effect on your brain, improving cognitive skills not related to language and even shielding against dementia in old age.

它可以对你的大脑产生深远的影响，提高与语言无关的认知能力，甚至预防老年痴呆。

But now it's going to make more sense because in that case we were just talking about single electron atoms, and now we're talking about a case where we actually can see shielding.

但是现在能讲得通了,因为在那个情况中我们仅仅是现在我们讨论的是,讨论单电子原子，看到屏蔽的案例,我们能看到屏蔽。

All right. So now that we have a general idea of what we're talking about with shielding, we can now go back and think about why it is that the orbitals are ordered in the order that they are.

现在我们对于谈论的屏蔽,有一个整体观点了，我们现在可以回过头来考虑,为什么轨道是按照,那种规则排列的。

So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.

抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它，我们从原子核中留下的，全部有效电荷就是，所以，在我们的第一个例子中,我们的第一种极端情况。

But a solar storm has the potential to disrupt the shielding effect, and severe space weather can have harmful effects on a wide array of technological systems, including satellite operations, communications, navigation and electric power grids.

For instance, if a stock yields 2%-4%, then the price of the stock can decrease by that amount over the next year, therefore shielding your loss to some extent.
