redshiftsCOCA⁵⁰²¹²BNC⁷⁵⁹⁹¹⁺¹² 基本例句 n.天体红移;红向移动原型redshift的三单 Eleven QSO candidates have been confirmed from the UKST prism plate of the field0112-35. Their redshifts, finding charts and the spectra are presented. 对天区0112-35的 UKST物端棱镜底片上的11个类星体候选者进行了光谱观测,证实为类星体,给出了它们的红移值、证认图及光谱图。 cnki The periodicity in the distribution of quasar redshifts is interpreted assuming that the cosmological space is a topologically compactified manifold like three dimensional torus. 若宇宙空间是拓扑紧化流形,例如三维环面,则类星体红移分布中的周期性即可加以解释。 cnki Cosmological redshifts, however, are generally considered to be different from the Doppler effect. 宇宙学的红移现象,通常区别于多普勒效应。 yeeyan Firstly, a group of redshifts were determined using the emission line info extracted from the observed spectrum; 首先,利用提取出的发射谱线信息确定一组红移候选; cnki Quasars are objects that appear stellar or almost stellar, but their enormous redshifts identify them as objects at very large distances. 类星体是物体出现恒星或几乎恒星,但其巨大的红移确定物体他们非常大的距离。 lixiaolai Take account of the selection effects caused by the spectra identification we have limited to analyse the QSO's with redshifts between 1.9 to 2.5. 考虑到谱线证认中存在的选择效应的影响,我们将分析样本限制在红移由1.9—2.5范围内的类星体。 cnki Then, with a few assumptions about the curvature and contents of the universe, they can reconstruct the positions of those objects from redshifts. 然后,通过一些关于宇宙曲率和内容的假设,科学家们能够重建这些物体的位置。 yeeyan We discover that it is hard for us to distinguish different neutron star models by the simple constraints of masses, redshifts and rotations on mass- radius relations. 结果发现,质量、红移及旋转频率对相应状态方程质量-半径关系的简单限制很难区分不同的中子星模型。 boshuo We discuss the observational masses, redshifts and rotation frequencies constraints on the equations of state in the cores of neutron stars. 利用目前积累的脉冲星质量、红移和旋转频率的观测数据,我们探讨了它们对中子星核区状态方程的限制。 boshuo |
