And for that, we have to use a chemical solution called the developer.

要实现这个目的，我必须使用一种叫显影剂的化学溶液。

Chemical developers vary depending on the kind of film you're using.

化学显影剂决于所用胶卷的种类。

So what we've done, What we've aimed to do is create a new powder for developing fingerprints.

我做的事情，志在发明一种新的指纹显影粉末。

In order to make that image appear clearly, the film needs to be developed with another chemical reaction!

为了使图案清晰地显示出来，胶卷需要通过其他的化学反应进行显影！

First introduced in 1947, peel-apart instant film develops by manually peeling apart layers after a photo is taken.

撕拉片于 1947 年首次推出，其显影方式是在拍照后手动撕开相纸夹层。

Scientists hope the data gathered will give them information on the internal structure of the planet, its surface and physical development.

学家望它的数据汇总在一起能够让他了解水星的内部结构、表面和物理显影。

He worked fast and clumsily, spilling developer and fixer all over the ground.

他动作迅速但笨拙，不小心将显影液和定影液洒了一地。

These tools include the photoresist spin coater, photolithography tool, developer, and photoresist stripper.

这些工具包括光阻旋涂机、光刻设备、显影剂和光阻剥离剂。

And the youngest was Apichatpong Verasethakul's first feature, Mysterious Object at Noon.

最年轻的是阿彼察邦·韦拉斯哈古的处女作《正午显影》。

Powders are the most widely used, most successful methods for developing fingerprints, But they have lots of issues already in there.

粉末是应用最广、最具成效的指纹显影剂，但其中存在许多问题。

Quiet. I'm trying to get a picture.

闭嘴好吧 我在想办法让它显影。

The wafer then goes to the developer and the weakened photoresist is washed away.

然后硅片会被送到显影剂中，弱化的光刻胶会被冲洗掉。

One more quick flash in the dark, and already, the photo was developing in Kyle’s hand.

又在黑暗中快速闪了一下光， 照片已经在凯尔手中显影了。

The important thing is that developers include reducing agents: chemicals that generally donate electrons to other compounds during a chemical reaction.

重点是显影剂里包含还原剂，它能在化学反应中给其他化物提供电子。

So when the copy is developed, the areas where the highlights were in real life show up brighter on the print.

所以当副本显影时，现实中明亮的部分打印出来时也会更亮。

Since they're made partly of calcium, they'll usually be radiopaque, meaning you can see them on x-ray, here's an example showing pigmented gallstones on x-ray.

因为胆红素结石部分由钙组成，故它无法透过射线，意味着可在X光片上看到这些结石，这里是一个胆色素结石在X射线下显影的例子。

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，并且胶卷上的该点也会变得更暗。

There are also uric acid stones which are red-brown in color and radiolucent under an Xray, meaning that they're transparent to x-rays and don't show up very well.

另外还有呈红棕色的尿酸结石，在X光片上不显影，说明X射线可以穿过它，不能很好地显影。

Sometimes, instead of oxalate, the calcium binds a negatively charged phosphate group to form calcium phosphate stones, which are dirty white in color and alsop radiopaque on an Xray.

有时候，钙离子与带负电荷的磷酸基团结而非草酸，形成的磷酸钙结石呈灰白色，也在x线片上显影。

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。
