摘要 通过对宇宙微波背景辐射光子极化的观测,可以精确测量张标比.在对暴涨宇宙模型进行限制的时候,它将提供一个非常有力的工具.就一个单标量场暴涨模型而言,要同时预言比较大的张标比和谱指数跑动是有困难的.为了试图解决这一问题,本文作者提出了一种具有幂级数形式势能的单暴涨场模型.研究表明,这个具有无穷多项势能的暴涨模型不仅理论上是自洽的,而且能够缓解上述问题. The tensor-to-scalar ratio can be measured by observing the polarization of photos in the cosmic microwave back- ground. It shows very strong power on constraining i^fflation models. However, for a single field inflation model, it can not predict both a large tensor-to-scalar ratio and a large running of the scalar power spectral index. To solve this problem, the authors propose an inflation model with power series potential. It is found that this model is consistent with latest observations.
