摘要：
We propose two cosmological models in order to explain the universal baryon density parameter Omega(b)h(2) inferred from different observational data: One is from the Big-Bang nucleosynthesis, and the other is from the cosmic microwave background fluctuations. Our proposed theoretical models axe the lepton asymmetric Universe model and the baryon inhomogeneous Big-Bang nucleosynthesis model.
