摘　　要：研究了2维O(1,1)对偶弦模型中的β函数,推导了β函数的重整化群方程,获得了无弦源耦合与弦源耦合的宇宙学解,还讨论了这些解的一般性质.结果表明弦源耦合的宇宙学解具有自对偶性,并可用来描述前大爆炸时宇宙的演化过程.The β functions in two-dimensional O（ 1,1 ） duality string model are studied in this paper, the renormalization group equation of β functions are derived. Moreover, the cosmological solutions without and with string sources coupling are obtained, the general properties of these solutions are also discussed. The result indicates that the cosmology solution with string sources coupling has the self-duality and can be used to describe evolution process of pre-big bang universe.
