Instead of rambling this party had preserved a dignified homogeneity, and assumed to itself the function of representing the staid nobility of the countryside— East Egg condescending to West Egg, and carefully on guard against its spectroscopic gayety.

这到处转悠，而是正襟危坐，自成一体，并且俨然自封为庄重农村贵族代表——东卵屈尊光临西卵，他们小心翼翼，提防灯红酒绿欢乐会有损体面。

Well, within the next 15 years, we could start seeing real spectroscopic information from promising nearby planets that will reveal just how life-friendly they might be.

They found spectroscopic signs that the galaxy harbored two star-packed clumps with record-breaking low levels of elements heavier than helium.

他们发现光谱学迹象表明，该星系中蕴藏着两个挤满恒星云团，其中重于氦元素含量之低打破了记录。

Even better: Alcor is a spectroscopic binary, too!

开阳伴星也是分光双星！

With other spectroscopic techniques, we can determine if an object is spinning and how fast, whether it has a magnetic field and how strong it is, and even how massive and dense an object is.

用其他光谱技术，我们还可以确定一个物体是否在旋转，速度有多快，它是否有磁场，磁场有多强，甚至一个物体质量和密度有多。

In even a small telescope you can see that Mizar is actually a visual binary… but it turns out that both of those two stars making up Mizar are actually SPECTROSCOPIC binaries, too.

即使是用一个小望远镜，你也可以看到开阳星实际上是目视双星… … 但事实证明，组成开阳星这两颗恒星其实也是分光双星。

These kinds of stars are called SPECTROSCOPIC BINARIES.

这类恒星被称为分光双星。

Spectroscopic follow-up of this remarkable galaxy is critical to Webb's mission of expanding cosmic frontiers.

对该奇特星系进行光谱后续观测对韦伯望远镜拓展宇宙边界使命至关重要。

But from another spectroscopic analysis, based on the electrons, they showed that its gold was an impure alloy, in contrast to the near 24-carat version of the metal used for coins made in Rome.

但是，根据另一项基于电子光谱分析，他们表明黄金是一种纯合金， 这与罗马制造硬币所用近 24 克拉金属形成鲜明对比。

In addition, they caught a never-before-seen glimpse of Jupiter's composition  beneath its dense cloud tops, as spectroscopic readings were able to identify material that had  been splashed upward by the comet's impact.

此外， 他们首次窥见了木星浓密云顶之下前所未见成分，因为光谱读数能够识别出被彗星撞击溅起物质。

Greatest painter enjoys global respect The Reichs Museum in Amsterdam invited the public to follow centimeter by centimeter, a revealing spectroscopic examination of Re that's the night.

最伟画家享有全球尊重 阿姆斯特丹莱克斯博物馆邀请公众跟随厘米-by-厘米，一个揭示性光谱分析，那是夜晚。

Others, copying them added thalium 1861 and indium 1863 spectroscopic analysis is greatest triumph though was helium 1868.

其他仿效他们，在1861年添加了铊，在1863年添加了铟，但光谱分析最成就还是在1868年发现了氦。

Methane plumes, invisible and odourless, can be spotted only by using specialised infrared or spectroscopic equipment.

甲烷羽流， 无形且无味，唯有借助专业红外或光谱设备方能被察觉。

Chandrayaan-1 (carrying a NASA Moon Minerology Mapper) found the first  definitive spectroscopic signatures of water ice in dozens of craters congregated  around the Moon's poles.

Chandrayaan-1（携带 NASA 月球矿物学绘图仪）在月球两极周围聚集数十个陨石坑中首次发现了水冰明确光谱特征。

Standard stuff - carbon date the cork, run a molecular test on the wax, spectroscopic refraction on the glass.

一些常规程序根据碳含量鉴别软木塞年份，给蜡做分子测试，分光镜折射来测试玻璃瓶身。

Spectroscopic redshifts involve analyzing the spectral lines observed in distant galaxies and comparing them with those we observe on Earth.

光谱红移涉及分析远处星系中观察到光谱线，并将其与我们在地球上观察到进行比较。

So the spectroscopic redshift is the gold standard for determining extragalactic distances.

因此，光谱红移是确定河外距离金标准。

Although HD1 appears red, a detailed spectroscopic analysis of this galaxy reveals that it is unusually bright in the ultraviolet region of the EM spectrum.

尽管HD1看起来是红色，但对该星系详细光谱分析显示，它在电磁波谱紫外区域异常明亮。
