准稳态及相关宇宙学模型的历史回顾
Quasi-Steady-State and Related Cosmological Models: A Historical Review
摘要：
自从20世纪60年代后期标准的热大爆炸宇宙论出现以来，宇宙学一直被有限年龄模型所主导。然而，与之对立的观点，即宇宙存在了无限的时间，仍然被少数研究人员所捍卫。这种观点的根源可以追溯到很久以前的历史，在20世纪50年代和60年代，提出了几个模型来反对大爆炸范式。最重要的替代模型是1948年提出的稳态宇宙学，它是均匀膨胀的，而不是表现出周期性的行为。在20世纪90年代的一个修正版本中，它被发展成准稳态宇宙学模型（QSSC）。从历史的角度来看，这个模型，以及其他一些相关的模型，可以被看作是宇宙学思想传统的最新例子，可以追溯到古希腊。本文介绍了QSSC模型产生的背景和发展过程。
英文摘要：
Since the emergence in the late 1960s of the standard hot big-bang theory, cosmology has been dominated by finite-age models. However, the rival view that the universe has existed for an indefinite time has continued to be defended by a minority of researchers. This view has roots far back in history and in the 1950s and 1960s several models were proposed in opposition to the big-bang paradigm. The most important of the alternative models, the steady-state cosmology proposed in 1948, was uniformly expanding rather than exhibiting a cyclical behaviour. In a much revised version it was developed into the quasi-steady-state cosmological model (QSSC) of the 1990s. From a historical point of view, this model, and a few other related models, can be seen as the latest examples of a tradition in cosmological thought that goes back to ancient Greece. The paper describes the background and development of the QSSC model.
