That huge increase in luminosity does more than just make the Sun bright, though.

然而，光度的巨增不仅仅使太阳明亮。

One is to look for stars in the nearby universe whose absolute luminosity we know.

一种是附近的宇宙中寻找我们知道其绝对光度的恒星。

In addition, the sun's increasing luminosity will cause severe effects on Earth.

此外，太阳光度的持续增加将对地球造成严重的影响。

The sun was already sending sufficient light under these waves. The tiniest objects remained visible.

太阳已经把足够的光度照到水底下来，最微小的物体也可以。

After that, we'll pass it through the spectrometer to measure how much glucose is present.

之我们再使用分光光度来测定其中含有多葡萄糖。

The company uses a tool called the Spectrophotometer to compare the same color on different surfaces.

潘通公司会使用一种名为分光光度的工具来比较不同表面上的相同颜色。

By connecting the spectrophotometer to a smartphone, a smartphone app is used to show the results.

将分光光度和智能手机连接，智能手机上就可以显示结果。

Finally in 1 billion years the sun's luminosity will have increased 10% from its current state.

最，亿年，太阳的光度将比目前的状态增加 10%。

When it turns into a red giant, the Sun will increase its luminosity by an incredible 2000 times.

当太阳变成一颗红巨星时，它的光度会增加2000倍，分惊人。

We were not 100 feet from the blazing core of light, whose glow grew stronger and dazzled the eyes.

人们距白热的焦点不到一百英尺了，光度更强起来，照得我们的眼睛发昏。

No, sir, I answered with conviction. Not even angel-wing clams or salps have ever given off such a powerful light.

不，我很有把握地答，富拉得或沙尔已之类的动物决不能发出这么强的光度。

This awesome tool conveniently tells you information about a star’s temperature, luminosity, color, and more.

这个很棒的工具可以方便地告诉您有关恒星温度、 光度、颜色等的信息。

It's an incredibly slow but inexorable process: the Sun's increased in luminosity by about 40% since it was born.

太阳的光度自诞生以来已经增加了大约40%。

3% of the Sun's luminosity is the most light that Jupiter could hope to spit out.

太阳光度的 0.3% 是木星希望吐出的最大光度。

The drive was dark at first, then acquired luminosity as I became accustomed to the stars.

车道起初是黑暗的， 然随着我习惯了星星而获得了光度。

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—吸光度为99.95%。

Set astern of the pilothouse is a powerful electric reflector whose rays light up the sea for a distance of half a mile.

领航人的笼间面，装有一座光度很强的电光探照灯，半海里以内的海洋都可以照亮。

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

因此，对比红光与红外光的吸光度可提供化学指纹图谱，以消除血管尺寸效应。

A century ago astronomers Ejnar Hertzsprung and Henry Norris Russell made a graph, in which they plotted a star's luminosity versus its temperature.

一个世纪前，天文学家埃尔纳·赫茨普鲁格(Ejnar Hertzsprung)和亨利·诺里斯·罗素(Henry Norris Russell)绘制了一幅恒星光度与温度的关系图。

The device also has a diopter adjustment built in, so people who wear glasses or contact can use it without wearing additional vision correction.

该设备还内置了屈光度调节功能，因此佩戴眼镜或接触的人无需佩戴额外的视力矫正即可使用它。
