Mineral products that contain zinc oxide and titanium dioxide will still be allowed.

含有氧二氧钛的矿产品仍然是允许的。

You can't convert exhaust back into gasoline, but, with some work you can convert, say, zinc oxide back to zinc.

我们无法将尾气转换回汽油，但我们可以使用一些方法，将氧转回。

Only two inorganic sunscreen ingredients have been approved by the FDA: zinc oxide and titanium dioxide.

只有两种无机防晒霜成分获得了美国食品药物管理局的批准：氧二氧钛。

For example, in a typical alkaline double-A battery, zinc metal reacts with hydroxide ions, changing into zinc oxide and releasing electrons at the negative terminal.

例如，在一个常见的碱性 AA 池中，金属与氢氧离子发生反应，转为氧，并从池负极释放子。

Physical blockers, like zinc oxide or titanium dioxide, reflect the Sun's rays by acting as a physical barrier.

物理防晒像是氧或二氧钛，像物理性屏障一样反射太阳射线。

On the back under " active ingredients" , you can find whether zinc oxide, titanium dioxide, and those coral-harming components are present.

在背后的" 成分表" 中，你可以发现防晒产品是否含有二氧，二氧钛，或是对珊瑚有害的成分。

Some of these have, by the way, zinc oxide, titanium oxide, and chemical-based components, okay?

顺便提一下，其中一些产品含有氧、二氧钛以及学成分，好吗？

But what I love about it is A, it has sunscreen in it, and B, once it's rubbed in and it doesn't look like I have zinc all over me, it really gives the skin a nice glow.

但我钟爱它的原因有二：一是它含有防晒成分，二是涂抹均匀后， 看起来不像满脸都是氧，反而能让肌肤焕发出自然的光泽。

Because in fact, you know, in real life, her face was incredibly, her lips, all of her skin, you know, the burn, the zinc, everything was, that was very real.

因为在现实生活中，她的脸真的受到了极大的影响， 她的嘴唇，所有的皮肤，你知道，烧伤、氧等等，这一切都非常真实。

In here elemental zinc is going to react with manganese dioxide, also known as manganese four oxide, to produce manganese three oxide and zinc oxide.

在这里，元素将与二氧锰反应，也就是人们常说的四价锰氧物，生成三价锰氧物氧。

That’s because the battery oxidizes the zinc that’s closer to the edge first, and eventually, there are zinc oxide molecules throughout the entire layer.

那是因为池首先会氧靠近边缘的，最终整个层中都会充满氧分子。

So I'm a huge fan of mineral sunscreens, like a 20% zinc, and I can recommend one as well.

所以我非常喜欢矿物质防晒霜，比如含20%氧的，我也可以推荐一款。

One way to avoid that is to look for a primer that's mattifying that contains zinc oxide.

- 避免这种情况的一种方法是寻找一种含有氧的哑光底漆。

Why would people not use zinc oxide formulas?

为什么人们不使用氧配方？

So when this network is big enough throughout the zinc layer, the battery has hit a maximum bounciness, and more oxidation doesn’t really have an effect.

所以当这个氧网络在整个层中足够大时，池的弹跳性就达到了最大值， 更多的氧作用对其影响不大。

Here's what most everybody seems to accept, that mineral-based sunscreens, meaning sunscreens that tend to include either zinc oxide or titanium dioxide, or both in some cases, are generally thought to be safe up to concentrations of 25%.

大多数人似乎都认同的是，矿物基防晒霜，即那些通常含有氧或二氧钛，或在某些情况下两者都含有的防晒霜，普遍认为在浓度高达25%时是安全的。

In fact, zinc oxide is sometimes even used in golf balls to make them more bouncy!

事实上，氧有时甚至被用于高尔夫球， 使它们更具弹性！

It has been explored whether or not titanium dioxide is more risky than zinc oxide.

已探讨过二氧钛是否比氧更具风险。

And two: the zinc bonds with oxygen to create molecules of zinc oxide.

而且第二点：与氧气结合生成氧分子。

In the used-up part of the battery, the zinc oxide molecules form a network that’s almost like a trampoline where the kinetic energy can be momentarily stored, then released.

在用过的池部分，氧分子形成了一个类似蹦床的网络， 可以暂时储存动能， 然后释放。
