So, it was boiling water, salt, sugar, rosemary, and that'll really brine and add kind of a seasoned flavour throughout, but without taking away their wonderful freshness, not cooking them, just kind of blanching them.

用是沸水，盐，糖，迷迭香，这些都能卤化番茄，给它增加味道，但不会损失番茄新鲜度，不是煮，只是焯一下。

In particular, one promising feature of metal halides is that they can be used to make new types of solar cells which are more efficient at converting sunlight into electricity than the silicon-based cells currently employed.

特别是，金属卤化一个非常棒特点是，它们可以用来制造新型太阳能电池，这种电池比目前使用硅基电池将太阳光转化为电能更高。

The silver ions in the exposed halide crystals, the ones with metallic silver in them, will have more reactions with the developer, creating more metallic silver in those grains.

曝光卤化晶体含有金属，该晶体与显影剂反应更加充分，从而生成更多金属。

If a halogen, such as bromine, is added in the place of hydrogen, the reaction is called halogenation.

如果用卤素（如溴）代替氢进行反应，这种反应称为卤化。

This means that instead of converting sunlight into electricity, metal-halide perovskites can operate in reverse, by emitting light in response to an electric current.

这意味着金属卤化钙钛矿可以反向工作，不需要将阳光转化为电能，而是可以通过发光来响应电流。

Halogens can react with metals to form halide crystals, in which the atoms become arranged in a very orderly grid called a lattice.

卤素能与金属反应生成卤化晶体，晶体中原以非常有序格排列，称为晶格。

To produce such screens, Dr Hou and his team developed a way to bind tiny " nanocrystals" of lead-halide perovskites into a specially treated synthetic glass composite.

为了制造这种屏幕，侯博士和他团队开发了一种方法，将微小卤化铅钙钛矿“纳米晶体”结合到经过特殊处理合成玻璃复合材料中。

Another name for a halide is a salt.

卤化还被叫做盐。

The photons don't change every halide.

光不会改变所有卤化。

Silver halides are just some atoms of silver bound to atoms of any element known as a halogen, which includes things like bromine, chlorine, and iodine.

卤化由原与卤素原组成，卤素原包括像溴、氯、碘等元素。

Typically, it's silver halide crystals floating around in gelatin, which solidifies on the film.

有代表性地是悬浮在胶状体中卤化晶体，其最终固定在胶卷上。

If more photons hit a silver halide crystal, more reactions with the developer can happen, and that spot on the film strip becomes darker.

更多光撞击卤化晶体，会引发更多显影剂反应，并且胶卷上该点也会变得更暗。

Other molecules can break that double bond as well. If a halogen, such as bromine, is added in the place of hydrogen, the reaction is called halogenation, a water molecule, hydration, oxygen, gas, oxygenation. You get the idea.

其他分也能断裂该双键。如果用卤素（如溴）取代氢，则该反应称为卤化；若加入水分，则称为水合；若加入氧气，则称为氧化。以此类推。

You also learned a little bit about cis-trans isomerism and learned a few important reactions of alkenes and alkynes such as hydrogenation, halogenation, and polymerization.

你还了解了一点关于顺反异构体知识，并学习了一些烯烃和炔烃重要反应，如氢化、卤化和聚合。

But the basic idea is that they react with the remaining silver halide crystals to create an image you can see.

但基本思路都是与残留卤化晶体反应，生成可见图案。
