noble gases

常见例句

What do we know about the noble gases?
那我们对惰性气体有哪些了解呢？
And the answer is yes, we know something about the noble gases.
答案是肯定的，我们对惰性气体有所了解。
The first ionization potentials of the noble gases provide a measure of how firmly the outer electrons are held by the effective nuclear charge.
稀有气体的一阶电离势提供了一个评价的标准，能衡量外层电子被有效核电荷束缚的强度。

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?
那么，你认为稀有气体的电子亲和能,应该是一个高的正值，一个低的正值，还是一个负值？

ECONOMIST: Medical imaging
If the 3He imaging project succeeds, the researchers expect it to pave the way for images based on other noble gases—such as the xenon isotope 129Xe.
