In the case of low and high velocities, the analytical expressions of the electronic stopping power and the effective charge are obtained, respectively.

在低速和高速情况下，分别得到了有效电荷数和电子阻止本领的解析表示式。

In the article we suppose that it is a better way to study bond's polarizability that the combination of infra-red spectrum data and polarizability equation calculates effective charge.

红外光谱数据与极化方程结合计算有效电荷的方法是研究键极化性质的较好途径。

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。

2 So what we end up saying is that the z effective or the effective charge that that first electron feels is now going to be plus 2.

第一个电子感觉到的有效的z或者有效电荷现在是,我们再一次将它带入我们的方程。

The first is this the z effective, or how much charge is actually in the nucleus that's felt, Z or the I guess we would say the z, how much the charge is on the nucleus that holds it close together.

第一个是有效核电量，或者说实际感受到的核电荷量，又或者我想我可以说就是，使它们保持在一起的,原子核的电荷量。

Prof Glenn Lyons, from the University of the West of England, it was difficult to know how effective a charge would be until it was implemented.

Saab is apparently suspending all new car, powertrain, emissions and parts warranties, along with recall campaigns, certified pre-owned coverage and no-charge maintenance programs effective immediately.
