Eventually, she and her colleagues worked out that the dragonfish reflects just one in every 2,000 photons incident upon it-an absorbance of 99.95%.

最终，她和她的同事发现深海龙鱼仅反射入射到其表面的1/2000的光—光度为99.95%。

On the right I have the absorbance.

右边是光度。

So contrasting the absorbance of red to infrared light provides a chemical fingerprint to eliminate the blood vessel size effect.

，对比红光与红外光的光度可提供指纹图谱，以消除血管尺寸效应。

We could measure the absorbance of it.

我们可以测量它的收率。

And so we can use Beer-Lambert's law to make predictions on the concentration based on the absorbance levels.

, 我们可以使用Beer-Lambert定律根据光度水平对浓度进行预测。

Look what's happening to the absorbance.

看看光度发生了什么。

We're going to set that to absorbance.

我们将把它设置为光度。
