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

其人效，在1861年添加了铊，在1863年添加了铟，但谱分析最大成就还是在1868年现了氦。

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

因此，谱红移是确定河外距离金标准。

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.

谱红移涉及分析远处星系中观察谱线，并将其与我在地球上观察进行比较。

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.

好吧，在未来15年内，我可以开始看真正谱学信息从附近有希望行星开始，去揭示一个星球有多适合居住。

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，但对该星系详细谱分析显示，它在电磁波谱紫外区域异常明亮。

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.

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

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双星。

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

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.

用其谱技术，我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大。

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谱分析，表明黄金是一种不纯合金， 这与罗马制造硬币所用近 24 克拉金属形成鲜明对比。

With the help of the Anglo-Australian Telescope, or AAT, a 12.8 foot or 3.9 meter telescope, and the Gaia space observatory of the European Space Agency, they conducted spectroscopic imaging of the stellar streams in the southern hemisphere.

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.

这伙人不处转悠，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——东卵人屈尊临西卵，小心翼翼，提防灯红酒绿欢乐会有损体面。
