noble gases

常見例句

What do we know about the noble gases?
那我們對惰性氣體有哪些了解呢？
And the answer is yes, we know something about the noble gases.
答案是肯定的，我們對惰性氣體有所了解。
The first ionization potentials of the noble gases provide a measure of how firmly the outer electrons are held by the effective nuclear charge.
稀有氣體的一階電離勢提供了一個評價的標(biāo)準(zhǔn)，能衡量外層電子被有效核電荷束縛的強度。

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?
那么，你認為稀有氣體的電子親和能,應(yīng)該是一個高的正值，一個低的正值，還是一個負值？

I left out the noble gases here because they do something a little bit special, and actually, I'm going to give you one last clicker question today to see if you can tell me what you think noble gases do.
我并沒有把稀有氣體算在里面,因為它們的電子親和能有點特別，實際上，我將會把這作為今天的,最后一個選擇題，來請大家告訴我,你們覺得稀有氣體電子親和能應(yīng)該是怎樣的。

We have elements that are totally inert, and we have examples of this, the noble gases, dominantly inert.
因為那些元素都是惰性的，而且我們可以舉出些例子，比如惰性氣體，完全是惰性的。

Perhaps the next Nobel prize involving noble gases will be for medicine, not physics.
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.
