查询词典 redshift

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。

The redshift periodicity is evidence for past oscillations in the expansion rate of the universe...

该红移的周期性是过去宇宙膨胀速率变化的证据。。。

The current galaxy redshift quasar C, have not yet accepted explanation.

目前对类星体C和星系的红移还没有公认的解释。

The ω for the scalar field model is not a constant but evolves with the redshift z.

各种标量场模型的物态方程ω是演化的，有的可以给出ω＞-1，有的可以给出ω＜-1。

The animation below schematically shows what a redshift and blueshift might look like , again using a car as an example.

下面的动画显示了红移或蓝移看上去的可能样子。

A novel method for redshift determination and spectral line identification of celestial spectra is presented, which is based on the knowledge of feature spectral lines.

该文给出了一种基于知识的天体光谱的红移测量和谱线证认方法。

Redshift determination and spectral line identification are the most important partsin spectral recognition.

红移测量和谱线证认是天体光谱自动识别中最重要的内容。

The optimum reaction conditions and the influencing factors were studied. In the presence of gum arobic, arsenazo Ⅲ-barium in acid solution could combine with BSA to form a ternary complex leading to a redshift of absorption spectrum and significant increase of absorption peak intensity.

研究发现，在表面活性剂阿拉伯树胶存在下的酸性溶液中，偶氮胂Ⅲ-Ba配合物与BSA发生反应形成三元复合物，引起吸收光谱发生红移，吸收峰明显增高。

The prediction for the route gravitational redshift is consistent with the predictions for the deflection of light and the time dilation of the returned radar wave.

途中引力红移的预言与光的偏折和雷达回波时延的预言相洽。

However, unlike the light source relative to the rest of the observer to see is the colorless astigmatism, and the light source relative motion of the observer to see is the red-shift light ( achromatous astigmatism occurs redshift of red-shift light ); Although the different inertial reference frame of the observer can see the speed of light, after the Lorentz transformation is the same as after c; but a different observer are exposed to the light energy is not the same achromatous (astigmatism energy and achromatous astigmatism occurs after the red-shift of red-shift of the light energy is out of the same ).

但是，与光源相对静止的观察者看到的是无色散光，而与光源相对运动的观察者看到的是红移光（无色散光发生红移后的红移光）；虽然，不同惯性参照系的观察者看到的光速，经过洛伦兹坐标变换后都一样为c；可是不同的观察者所承受到的光能量是不相同的（无色散光的能量和无色散光发生红移后的红移光能量是完全不相同的）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
