noble gases

常見(jiàn)例句

What do we know about the noble gases?
那我們對(duì)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(duì)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(shì)提供了一個(gè)評(píng)價(jià)的標(biāo)準(zhǔn)，能衡量外層電子被有效核電荷束縛的強(qiáng)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(rèn)為稀有氣體的電子親和能,應(yīng)該是一個(gè)高的正值，一個(gè)低的正值，還是一個(gè)負(fù)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(méi)有把稀有氣體算在里面,因?yàn)樗鼈兊碾娮佑H和能有點(diǎn)特別，實(shí)際上，我將會(huì)把這作為今天的,最后一個(gè)選擇題，來(lái)請(qǐng)大家告訴我,你們覺(jué)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?yàn)槟切┰囟际嵌栊缘模椅覀兛梢耘e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.
