By means of time-resolved laser-induced fluorescence spectroscopic technique, two samples of Er3+∶YAG with 10.5% and 8.4% concentrations were resonantly excited with ultraviolet lasers at 262 nm and 276 nm, and the fluorescence spectra were recorded and the peak transitions were assigned in detail.

利用时间分辨激光诱导荧光光谱技术，用262 nm和276 nm紫外激光对原子数分数为x(Er3+)=10.5%和x(Er3+)=8.4%两种情况下Er3+∶YAG晶体的4D5/2和2H9/2能级分别共振激发，记录了每种情况下的荧光发射谱，对其中所有荧光谱峰对应的能级跃迁做了详细标定。

Methods The compounds were isolated by means of silica gel column chromatography and elucidated by spectroscopic experiments.

采用柱层析对植物中的提取物进行分离提纯，并利用现代波谱方法分析鉴定，确定化合物的结构。

F. Their structures were identified as betulone (1), 3,4,5-trimethoxyphenol-β-D-glucopyranoside (2),α-amyrin (3),β-amyrin (4),β-sitosterol (5), and stigmasterol (6) by spectroscopic evidence (IR, NMR, MS, etc.) and comparision of their spectral data with those of the literatures.

F。 的乙醇提取物中分离得到6个化合物，经波谱分析及与文献数据对照确定其结构分别为：betulone (1)、3，4，5-三甲氧基苯酚-β-D-吡喃葡萄糖苷(2)、α-香树脂醇(3)、β-香树脂醇(4)、β-谷甾醇(5)和豆甾醇(6)。

To put this on a more solid statistical foundation these two samples in the Teff = 5600–5900 K window were extended by adding 16 and 13 planet-host and comparison sample stars respectively, for which we have obtained new Li abundances from high quality spectroscopic observations using the same spectral synthesis tools.

在此温度范围中，通过利用同样的光谱合成手段，我们得到一批新的样本，它们的锂丰度同样由高质量光谱分析仪得出。这样，我们为这两组样本分别各增加16颗"有行星"恒星和13颗"无行星"恒星，使得统计结果更具有可靠性。

In particular many of the basic spectroscopic and spectrometric techniques were discovered in the early 20th century and refined in the late 20th century.

特别是许多基本分光光度技术和光谱技术在20世纪初期被人们发现，并在20世纪后期得以完善。

But that's not a totally fair comparison, because Spica is not just one star, but a spectroscopic binary.

但那并不是非常公正的比较，因为天门星不只是一颗星，而是可用分光镜看见的双体星。
