我们构建了一个高维宇宙学模型，在这个模型中，额外的维度在从膨胀到现在的整个宇宙历史中，通过立方洛夫洛克引力被冻结，在这两者之间有辐射和物质主导的制度。
We construct a model of higher dimensional cosmology in which extra dimensions are frozen by virtue of the cubic-order Lovelock gravity throughout the cosmic history from inflation to the present with radiation and matter-dominated regimes in between.
