When the mechanical properties of this new cartilage were tested, they showed that the regenerated cells were just as effective as the rabbit's naturally formed cartilage.

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。

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。

They might end up getting cancer." Virtual colonoscopy as a screening tool is quite effective thats one of the reason why national cancer Institute recommends this as one of the screening device."

It is found that the most effective way of dealing with this phenomenon was actually to cultivate the positive,to cultivate personal strengths, to cultivate and identify one's passions, ? to ask a question such as "what is meaningful to me in my life?

事实证明，处理这种现象,最有效的方法是,培养积极性和个人优点，培育激情，提出这种问题“我人生中什么是有意义的？

So we know that we can relate to z effective to the actual energy level of each of those orbitals, and we can do that using this equation here where it's negative z effective squared r h over n squared, we're going to see that again and again.

我们知道我们可以将有效电荷量与,每个轨道的实际能级联系起来，我们可以使用方程去解它,乘以RH除以n的平方,它等于负的有效电荷量的平方,我们将会一次又一次的看到它。

So, if we just rearrange this equation, what we find is that z effective is equal to n squared times the ionization energy, IE all over the Rydberg constant and the square root of this.

我们可以发现有效的z等于n的平凡，乘以电离能除以里德堡常数,这些所有再开方，所以等于n乘以,除以RH整体的平方根。
