研究了以最小耦合标量场为物质源的多维宇宙学模型降维后得到的有效四维理论。考虑了内部空间稳定的条件，并讨论了外部空间暴胀的可能性。电弱以及普朗克基本尺度的方法进行了研究和相互比较。结果表明，在不同的方法中，有效宇宙学常数和引力激子质量都存在重标度。
Effective 4-dimensional theories are investigated which were obtained under dimensional reduction of multidimensional cosmological models with a minimal coupled scalar field as a matter source. Conditions for the internal space stabilization are considered and the possibility for inflation in the external space is discussed. The electroweak as well as the Planck fundamental scale approaches are investigated and compared with each other. It is shown that there exists a rescaling for the effective cosmological constant as well as for gravitational exciton masses in the different approaches.
