摘要
研究了弦宇宙中的相变动力学模型,分析了极早期宇宙中的超弦相变和QCD相变.另外,计算了标度因子的膨胀比和弦耦合常数的变化比.
The dynamic model of phase transition in string cosmology is studied in this paper. The superstring phase transition and QCD phase transition in early universe are analysed. Moreover, the expansion ratio of scale factor and the variation ratio of string coupling constant are calculated.
