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

含有氧化锌和二氧化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，将氧化锌转化回锌。

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和药物管理局的批准：氧化锌和二氧化钛。

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 电池中，锌金属与氢氧发生反应，转化为氧化锌，并从电池负极释放电。

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

物理防晒像是氧化锌或二氧化钛，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化锌，二氧化钛，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化锌、二氧化钛以及化学成分，好吗？

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，锌元素将与二氧化锰反应，也就是人们常说的四价锰氧化物，生成三价锰氧化物和氧化锌。

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.

那是因为电池首先会氧化靠近边缘的锌，最终整个层中都会充满氧化锌分。

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化锌的哑光底漆。

Why would people not use zinc oxide formulas?

为什么人们不使用氧化锌配方？

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

事实上，氧化锌有时甚至被用于高尔夫球， 使它们更具弹性！

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，即那些通常含有氧化锌或二氧化钛，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。

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

而且第二点：锌与氧气结合生成氧化锌分。

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

已探讨过二氧化钛是否比氧化锌更具风险。

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.

在用过的电池部分，氧化锌分形成了一个类似蹦床的网络， 可以暂时储存动能， 然后释放。

Meaning, sunscreens containing zinc oxide and titanium dioxide are probably safe, or at least have been deemed safe enough that they are freely available on the market.

因此， 含有氧化锌和二氧化钛的防晒霜可能安全，或者至少被认为足够安全， 以至于它们在市场上可以自由流通。

The more you use a battery, the more zinc oxide forms, and the higher the restitution – its ability to preserve kinetic energy.

你使用的电池越多，形成的氧化锌就越多，恢复力也就越高——即保持动能的能力就越强。

You can find sunscreens out there that have 25% zinc oxide or 25% titanium dioxide.

市面上可以找到含有25%氧化锌或25%二氧化钛的防晒霜。

And again, they always have other things in them, but what I mean is the only active ingredient in a zinc oxide only containing sunscreen is zinc oxide.

再说一遍，它们（纯锌氧化物防晒霜）里面总是含有其他成分，但我的意思是， 仅含锌氧化物的防晒霜中， 唯一有效的成分就是锌氧化物。
