红移

Based upon our first paper and continuing the "Standard candle" classification by use of the component linear distance D, we attain to the following statistical correlation of some type of Quasars with largest angular diameter Q_: the correla- tion between visual magnitude and redshift; the correlation between its absolute magnitude, radio-luminosity of single frequency, integral radio Iuminosity, colour in- dex difference Q and D.

本文在第I部分的基础上，继续用类星体射电子源线距D进行"标准烛光"分类，经过统计分析，得到了子源角径最大的一类类星体的一些统计规律：它的视星等与红移之间，它的绝对星等、单频射电光度、积分射电光度和色指数差Q与D之间有很好的相关性等。

We present semi-analytic models and Monte-Carlo simulations of QSO Lyman α absorption line systems...

本文结合星系形成理论，研究了低红移的类星体吸收线系统的起源与性质。

Therefore, the energy of π(superscript *) orbit decreases, the probability of optical absorption increases, the n→π(superscript *) electronic transition enhances, and the absorption band broadens and shows red-shift. The above phenomenon will result in the degradation of optical properties of ZnO/silicone white paint under proton exposure.

同时Si-O-Si链内氧原子未成键的孤对电子与邻近硅原子的3d空轨道配位，降低了π轨道的能量，提高了对光吸收的几率，增强了n→π电子跃迁，使吸收带红移，从而导致ZnO/silicone白漆光学性能退化。

The results also show the sensitivity is enhanced for the pigments with a larger anilide ring. It is important to note that the photosensitivity is greatly increased when the coupler component changed ftom a 2-hydroxy-3-naphthanilide to a 2-hydroxy-11H-benzocarbazole-3-naphthanilide coupler. Clearly, conjugation effects favours to enhance the photosensitivity.

偶合基部分共轭环的扩大使蒽醌偶氮染料的光敏性增加，特别是偶合基萘环上扩大了一个咔唑环后，其吸收光谱大幅红移，光敏性提高了几十倍，这一结果对红外偶氮光导染料的设计合成具有重要参考价值。

A redshift can be measured when light from a galaxy is broken up and spread out into a band of colors called a spectrum.

当从星系发出的光被分解展开成光谱的时候就可以测出红移了。

As annealing temperature increases, the crystal structure of QDs transforms from zinc blende to wurtzite, and the luminescence peaks are redshifted gradually.

随着热处理温度升高，晶体结构从闪锌矿型向纤锌矿型转变；发光峰逐渐红移。

The result indicated that absorption band of chromophore suffered bathochromic shift when electron-donating capability was increased.

结果表明：给电子基团给电子能力的增强使光谱产生一定的红移。

The main results are as follows.1. The UV-visible absorption spectra, the spin-trapping EPR measurements, and the DPA (9,10-diphenylanthracene) bleaching experiments showed that (1) HB-Net exhibits much improved light harvesting efficiency in the phototherapeutic window (600-900 nm) as the result of its remarkable absorption red shift with respect to HB;(2) HB-Net remains the generation abilities of semiquinone anion radical, superoxide anion radical, hydroxyl radical, and singlet oxygen, but with much lower efficiencies than that of HB, most likely due to its very short triplet excited state lifetime.

设计合成了寡聚吡咯酰胺修饰的竹红菌乙素衍生物HB-Net，利用紫外-可见吸收光谱、自旋捕获技术和DPA光漂白法详尽比较了HB-Net与HB的光动力性质，发现：(1) HB-Net的吸收光谱较HB有显著红移，在光疗窗口的吸光能力明显提高；(2) HB-Net能够产生半醌负离子自由基、超氧负离子自由基、羟基自由基和单重态氧，但由于其短的三重态寿命，这些活性物种的产生能力均弱于HB.2。

The maximal emission wavelength of eosin was red shifted in the polymer than in solution,the apparent Ka largened,and the dissociation equilibrium of indicator was shifted to direction,becau...

曙红染料在聚合物介质中由于极性的减弱，其最大荧光发射波长较在水溶液中红移，表观解离常数增大，对pH的响应区间向酸性方向移动。

The degree of "redshift" or "blueshift" is directly related to the object's speed in the direction we are looking.

红移或蓝移的程度直接取决于天体在我们视向的移动速度。
