摘要：

A primordial magnetic field (PMF) would be expected to manifest itself in the cosmic microwave background (CMB) temperature and polarization anisotropies, and also in the formation of large scale structure(LSS). In this article, we demonstrate how the PMF is an important cosmological physical process on small scales as follows, We also report the newest constraints on the PMF amplitude B-lambda and the power spectral index n(B) which have been deduced from the available CMB observational data by using our computational framework and the Markov chain Monte Carlo method. In particular we find that vertical bar B lambda vertical bar < 2.10(68%CL) nG and < 2.98(95%CL) nG and n(B)< -1.19(68%CL) and < -0.25(95%CL) at a present scale of I Mpc.
