查询词典 redshifts

Seeing that the regression equations with high correlation coefficient among redshifts, apparent magnitude and D have been established, it may be true that the redshift of these quasars is ma...

由于红移，视星等及D之间存在着相关系数较高的回归关系，所以，这种类星体的红移可能主要是宇宙学的。

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。

Compared with the PL-CDM model, the RSI-CDM model can raise the mass abundance of dark haloes for small mass haloes at lower redshifts, but it is not apparent on scales of massive mass haloes.

与PL-CDM相比，RSI-CDM在低红移处小质量暗晕的质量丰度较大，但在大结构质量晕中两者差别不明显，而且这个差异随著红移降低而增大。

That seem to indicate that there is periodicity in the abundances of measured galaxy redshifts...

&得到提示和确认。。。；这是一篇在网上出现频次很高的论文，用时髦的话来讲&很火

Using this device the spectra of some quasars of about 19m with large redshifts have been observed.

我们已用该装置观测到19m左右的具有大红移的类星体光谱。

Then, you will look in detail at some of the ways astronomers calculate the distance to galaxies, and you will learn how to find redshifts yourself.

然后，你将看到天文学家用不同的方法计算星系的距离，并且你将学到怎样独立找到红移。

Cosmological redshifts are measured to determine the scale of the universe.

关于图形的坐标刻度的因素和时间，暗物质的问题得到解决了。

As a midterm report, my colleagues and I recently completed an analysis of the first 200,000 galaxies with redshifts.

我与同事最近刚完成20万个星系红移的分析，做为计画的期中报告。

We summarize the observational and theoretical studies of quasars, and present the results of our studies on the Doppler redshifts of quasars.

本文综述类星体的观测和理论研究现状，详细介绍本人在攻读博士学位期间在类星体多谱勒红移方面的研究工作。

It is discovered that the oxide thickness increases as the starting titanium iso-propoxide increases while other parameters are kept exactly unchanged, and accordingly, the peak redshifts initially and then blueshifts; Moreover, as the mass of silver nitrate increases, the peak redshifts and the absorption band goes wider; the synthetic temperature exerts no effect on the final shape and size of the prepared nanoparticles, only tolengthen the needed reaction time.

结果表明：二氧化钛壳层的厚度随异丙醇钛量的增加而不断增加，其紫外一可见吸收峰先红移，然后蓝移；随着硝酸银的质量的增加，银核的直径增加，并可观察紫外一可见吸收峰的红移，峰宽也逐渐变宽；合成温度的变化对包覆纳米颗粒的大小及形状没有明显的影响，只是改变了合成所需要的时间。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
