摘　　要：仅当描述宇宙的宇宙学参数具有“恰当”的取值时,才能形成我们今天的宇宙。如何理解这种参数取值“恰当性”是现代宇宙学的重要问题之一。人择原理为这一问题提供了一种可能的解释。本文考察迪克、卡尔、里斯、林德、霍金、温伯格等人的宇宙学研究工作,探讨他们如何运用人择原理来解释大数巧合现象、宇宙学参数唯一性问题及宇宙学常数Λ问题。人择原理使现代宇宙学中人作为观察者的身份突显出来,并且为认识宇宙的本质提供了一种新的视角。Only when the cosmological parameters describing the universe have “appropriate” values could our universe be formed in its today’s form. How to understand the “appropriateness” of the values of these parameters is one of the important issues in modern cosmology. The anthropic principle provides a possible explanation for this problem. This article focuses on the cosmological research work of Robert Dicke, Bernard Carr, Martin Ress, Andrei Linde, Stephen Hawking, Steven Weinberg and others, and discusses how they use the anthropic principle to explain problems of the coincidence of large numbers, the uniqueness of cosmological parameters and the cosmological constant Λ. The anthropic principle highlights the identity of men as observers in modern cosmology and provides a new perspective for understanding the essence of the universe.
