查询词典 emission line

Bao made another mistake. He incorrectly thinks that the emission line region is the same as accretion disk!

我们确实应当化更多的时间去了解现代对类星体的观测结果，了解现有的理论。

A lowering of electron temperature would decrease the 703 nm emission line by reducing the indirect pumping to the upper level.

电子温度的降低会导致电子经由间接跃迁到较高能阶的比例降低而造成703 nm谱线的强度减弱。

Lyman-alpha blobs are so called because they strongly emit radiation due to the Lyman-alpha emission line of hydrogen gas.

Lyman-α云球名字的缘由是因为在氢气的Lyman-α谱线有强发射。

At visible wavelengths, the strongest emission line in this pattern is in the red part of the spectrum and is known as "Hydrogen-alpha" or just H-alpha.

在可见光波段，特征谱线中最强的发射线是光谱中红端的部分，就是人们熟知的"氢—α"或"H—α"。

This result can be used to qualitatively interpret the positive correlation and anti-correlation between the near infrared excess and equivalent width of Hα emission line, as observed in some Be stars.

此结果可用来解释一些Be星中观测到的红外超和Hα等值宽度的同时增长，也可用来解释另一些Be星中观测到的红外超和Hα等值宽度的相反变化。

IRAS 17213-3841 : Late Type Carbon-rich Star or Early Type Emission Line Star?

IRAS 17213-3841：晚型富碳星还是早型发射线星？

According to the measurement principle of Michelson interferometer for temperature and wind of atmosphere, the uncertainty of temperature was determined by the uncertainty in the apparent visibility of the emission line and the instrument visibility.

中国科学院西安光学精密机械研究所，西安 710119根据迈克尔逊风场探测干涉仪探测原理，所探测的温度不确定度是由装置调制度不确定度和发射线的表观调制度不确定度所决定的。

Bao. I think he does not know the : quasar physics at all!: A simple reason: astronomers detected redshifts of quasars based on the spectr : al lines emitted from the emission line regions, which are 0.1 to 1 parsec (1p : arsec=3.26 light years) far away from the central black hole. Therefore there : is very little effect from the gravitational redshift!

观察到的类星体的光可在几日内有明显的变化，可见类星体的发光区大小在光日尺度以下，即使你认为类星体的光谱线产生于吸积盘，那么吸积盘的大小须在光日尺度以下才能不相矛盾，请你说出一个你认定的类星体吸积盘的大小尺度与该尺度内所具有的质量，及因此计算出的可忽略的引力红移。

Firstly, a group of red.shifts were determined using the emission line info extracted from the observed spectrum; Secondly, the template was red.shifted according to the candidates, and the correlation between the observed spectrum and the redshifted template was measured.

首先，利用提取出的发射谱线信息确定一组红移候选；然后，按这些红移候选将静止模板光谱红移，计算所得光谱与目标光谱的相关值；最后，确定最大相关值对应的红移候选为目标光谱的红移。

Our calculated result shows that, except for the fluorescence emission, there coexists a Cerenkov line-like radiation mechanism in AGNs, which gives a significant contribution to the iron K-line emission, even moderately higher than the former.

两者共存于活动星系核中，而且以Cerenkov辐射机制为主。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
