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

有锌和二钛的矿产品仍然允许的。

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

物理防晒像锌或二钛，像物理性屏障一样反射太阳射线。

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：锌和二钛。

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，将锌转回锌。

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有二锌，二钛，或对珊瑚有害的成分。

Why would people not use zinc oxide formulas?

为什么人们不使用锌配方？

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寻找一种有锌的哑光底漆。

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

第二：锌与结合形成锌分子。

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

事实上，有时甚至会在高尔夫球中使用锌来使它们更有弹性！

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，锌金属与氢离子发生反应，转为锌，并从电池负极释放电子。

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

您使用电池的次数越多，锌的形式就越多，恢复能力就越高——它保存动能的能力。

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.

在这里元素锌将与二锰（也称为四锰）反应生成三锰和锌。

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.

那因为电池首先靠近边缘的锌，最终， 整个层都有锌分子。

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.

在电池用完的部分，锌分子形成一个网络， 几乎像一个蹦床， 动能可以暂时储存， 然后释放。
