我预测星系团的X射线光度函数的演变。主要是，我对待的假设，星系形成第一，然后集群在一起纯粹是由于引力。我发现，丰富的分布阿贝尔集群有利于这种情况下，而不是protocluster假说。亮度函数是通过将广义（对于所有的）cap omega..）具有幂律X射线光度-质量关系的星团的Press-Schecter演化质量函数（本文导出）;低红移星团的观测支持幂律关系。
I predict the evolution of the X-ray luminosity function of clusters of galaxies. Predominantly, I treat the assumption that galaxies form first, then cluster together purely as a result of gravitation. I show that the richness distribution of Abell clusters favors this scenario, rather than the protocluster hypothesis. The luminosity function is produced by combining a generalized (for all ..cap omega..) Press-Schecter evolutionary mass function for clusters (derived herein) with a power-law X-ray luminosity-mass relation; a power law relation is supported by observations of low-redshift clusters.
