标题： Angular Size in a Static Universe

摘要： 原则上可以通过测量已知物体的角直径随距离变化的关系来研究宇宙的几何性质。 因此，角直径分布为克劳福德（1991年，1993年）描述的静态稳定宇宙模型提供了关键检验，该模型中的物体角直径与红移之间存在简单而明确的关系。 结果表明，静态宇宙模型与星系直径和双源射电波束大小的观测结果吻合得比标准（大爆炸）理论更好，并且没有演化。 然而，在较大的红移时仍存在一个小的差异，这可能是选择效应造成的。 显示英文摘要

摘要： In principle the geometry of the universe can be investigated by measuring the angular size of known objects as a function of distance. Thus the distribution of angular sizes provides a critical test of the stable and static model of the universe described by Crawford (1991,1993) that has a simple and explicit relationship between the angular size of an object and its redshift. The result is that the agreement with observations of galactic diameters and the size of double radio sources with the static model is much better than the standard (Big Bang) theory without evolution. However there is still a small discrepancy at large redshifts that could be due to selection effects.
