But another thing that's cool about it is that, most strontium doesn't start out as strontium.

但另一件很酷事情，大多数锶刚开始这种元素。

For one thing, there's more than one isotope — or form — of strontium.

一方面，锶同位素或形式止一种。

And then, the strontium you eat and drink gets incorporated into your teeth!

然后，你吃和喝锶会进入你牙齿！

It's not getting any more new calcium, so the strontium ratio is set forever.

它再获得新钙，因此锶比例永远固定了。

The enamel coating your teeth contains lots of calcium, and strontium is like calcium in a lot of ways.

牙齿上牙釉质含有大量钙，锶在很多方面都和钙非常类似。

For one thing, there’s more than one isotope -- or form -- of strontium.

一方面，锶同位素或形式止一种。

But another thing that’s cool about it is that, most strontium doesn’t start out as strontium.

但另一件很酷事情，大多数锶以锶开始。

And the common ones in glow in the dark toys are zinc sulfide and strontium aluminate.

而夜光玩具中常见有硫化锌和铝酸锶。

It’s not getting any more new calcium, so the strontium ratio is set forever.

它再获得任何新钙，所以锶比例永远变。

Your teeth hold a lot of information about your life story, and scientists are learning how to read it, thanks to the properties of strontium.

由于锶特性，你牙齿包含了很多关于你生活故事信息，科学家们正在研究如何阅读这些信息。

All you'd need to do is let me borrow a couple of teeth, so I could measure how much of the element strontium is in them.

你需要做借我几颗牙齿，这样我可以测量它们中锶元素含量。

They use ytterbium or strontium – atoms that oscillate at visible light frequencies – and sync up lasers to the atomic oscillations for timekeeping.

他们使用镱或锶——以可见光频率振荡原子——将激光与原子振荡同步以进行计时。

For example, there was the leaking of highly radioactive water in 2016, and strontium and other radioactive substances were found to have exceeded normal standard in 2018.

例如，2016 年发生了高放射性水泄漏，2018 年发现锶等放射性物质超标。

A few years ago, NIST built a strontium clock that broke the world record for precision – that’s how accurately a clock tracks atomic oscillations.

几年前，NIST 制造了一个锶时钟， 打破了世界精度记录——这时钟跟踪原子振荡准确程度。

All you’d need to do is let me borrow a couple of teeth, so I could measure how much of the element strontium is in them.

你需要做让我借几颗牙齿，这样我可以测量其中有多少元素锶。

Strontium aluminate is more expensive, but it has a longer persistence, which means it emits visible light more slowly, and glows longer after being energized.

铝酸锶价格较贵，但持久性较长，这意味着它发出可见光速度较慢，充电后发光时间更长。

It's uncertain exactly how the discharge of water would impact marine life, but there are concerns about other radioactive isotopes of ruthenium, cobalt, and strontium accumulating in fish.

目前还确定放水会对海洋生物产生怎样影响，但人们担心钌、钴和锶等其他放射性同位素会在鱼类体内积累。

Americans dutifully adopted the new term, but many British users disliked aluminum, pointing out that it disrupted the -ium pattern established by sodium, calcium, and strontium, so they added a vowel and syllable.

美国人则完完全全地接受了这个新术语，但很多英国使用者却喜欢aluminum这个名字，指出其破坏了由sodium, calcium, and strontium建立起-ium形式，因此他们在aluminum基础上加了一个元音和一个音节。

For example, the strontium in the molars you got when you were around six will tell anthropologists where you lived for the first six or so years of your life.

例如，当你六岁左右时，你臼齿中锶会告诉人类学家你在生命前六年左右住在哪里。

Soon after taking up his position, Davy began to bang out new elements one after another—potassium, sodium, magnesium, calcium, strontium, and aluminum, or aluminium, depending on which branch of English you favour.

戴维上任后久, 开始一个接一个地推出新元素 - - 钾、钠、镁、钙、斯特朗チウム和铝, 或者铝, 这取决于你偏爱英语哪个分支。
