When a photon hits a crystal of silver bromide on a film strip, for instance, it knocks an electron off a negatively-charged bromide ion to create an atom of bromine.

例如，光子撞击胶卷表面的化银晶体时，从带负电的离子上“敲掉”一个电子，生成一个原子。

Chlorine levels are down 11.5% since they peaked in 1993, and bromine is at lower levels in the air, dropping 14.5 percent since its 1999 peak, the report said.

报告表示，其中氯的大气含量相比 1993 年的峰值下降了 11.5%，大气中的水平比较低，含量较 1999 年的峰值下降了 14.5%。

Researchers tested three anti-inflammatory drugs: bromfenac, used in eye drops, and carprofen and vedaprofen, both for treating conditions like arthritis in dogs.

研究人员们测试的三种抗炎药物为用滴眼液的芬酸，用治疗狗类关节炎症的卡洛芬和维达洛芬。

Newman said the reductions in chlorine and bromine levels came largely because of the limits set in the Montreal Protocol.

纽曼说，氯和含量的降低很大程度上是因为《蒙特利尔议定书》规定的限制。

Bromine — which does a better job of eating ozone but exists at lower levels in the air — dropped 14.5 percent since reaching a high point in 1999.

对臭氧层的破环作用更大，空气中的含量较低，自 1999 年达到峰值以来下降了 14。5%。

Like we saw last week, uranium undergoes many different types of nuclear decay, so not only does each uranium atom produce isotopes of krypton and bromine, but that process also produces many other isotopes of other elements.

就像上周看到的， 铀会经历多种不同的核衰变，因此每个铀原子不仅会产生氪和的同位素， 还会产生许多其他元素的同位素。

He believed he had discerned that like a musical scale every eighth element rhymed in the ways that sodium rhymed with potassium and chlorine with bromine The trouble with Newland's scheme.

他认为自己发现了一个规律，就像音乐中的音阶一样，每隔七个元素就会有一个元素性质上与前面的一个元素相呼应，比如钠和钾、氯和之间的关系。纽兰德的方案存问题。

And so we're going to have more of this form of bromothymol blue which is going to give us that yellow color.

因此，我们将会得到更多这种形式的百里酚蓝，它会给我们带来黄色。

Fine, take her off the Prozac and put her on Bromocryptene for the serotonin syndrome.

好 停用百忧解改用治疗血清素综合征的隐亭。

If the members were arranged in order of atomic weight, the middle element sodium strontium bromine selenium had a weight that was the average of the lightest and the heaviest of the three Diplyina called this the law of triads.

如果成员按照原子量排序，中间的元素钠、锶、、硒的重量是这三个元素中轻的和重的两个元素重量的平均值。迪普利纳将此称为三联律。
