为了解决宇宙微波背景各向异性角功率谱的低四极异常，最近提出了一个解耦时由于磁场存在而具有小偏心率的宇宙模型（即椭球宇宙）。我们对该模型进行了完整的统计分析，结果表明，在整个参数空间中，四极杆振幅增大的概率大于减小的概率。
A model of the Universe with a small eccentricity due to the presence of a magnetic field at the decoupling time (i.e., an ellipsoidal universe) has been recently proposed for the solution of the low quadrupole anomaly of the angular power spectrum of cosmic microwave background anisotropies. We present a complete statistical analysis of that model showing that the probability of increasing of the amplitude of the quadrupole is larger than the probability of decreasing in the whole parameters' space.
