Another name for a halide is a salt.

卤化物还被叫做盐。

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

但路都是与残留的卤化银晶体反应，生成可见的图案。

The photons don't change every halide.

光子不会改变所有的卤化物。

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

有代表性地是悬浮在状体中的卤化银晶体，其最终固定在卷上。

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物晶体，晶体中原子以非常有序的格子，为晶格。

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.

卤化银由银原子与卤素原子组成，卤素原子包括像溴、氯、碘等元素。

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

更多光子撞击卤化银晶体，会引发更多显影剂反应，并且卷上的该点也会变得更暗。

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.

曝光的卤化物晶体含有金属银，该晶体的银离子与显影剂反应更加充分，从而生成更多的金属银。

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，金属卤化物一个非常棒特点是，它们可以用来制造新型太阳能电池，这种电池比目前使用的硅电池将太阳光转化为电能的效率更高。
