摘要 在幂律暴涨宇宙中,以时空测不准原理作为出发点,提出一种新的计算模函数的方法.该方法能够使时空非对易效应以线性的形式贡献到密度扰动的谱指数中.通过分析和比较,发现这一类新的幂律暴涨宇宙模型能够预言一个比较大的张标比,该预言非常好地符合最新的实验观测结果. Based on space-time uncertainty principle, the authors propose a new class of power-law inflation. By using a new method of solving the mode function, a linear term contributes to the spectral index of the power spectra. In this model, it could predict a large tensor-to-scalar ratio, which is well consistent with latest observations.
