Λ CDM宇宙模型下的暗能量丰度
The Proportion of the Dark Energy in the ∧CDM Cosmology
摘要
ΛCDM宇宙模型是现在研究宇宙演化的模型之一.结合现在天文观测得到的数据,利用这一模型对宇宙中暗能量的丰度进行了计算,结果给出了在这种模型下的比较符合实验观测结果与理论分析的暗能量丰度为74%,这表明了宇宙的大部分是由暗能量所构成.
The A CDM cosmology is one of the models to study the evolution of the universe.Combined with the data of astronomy observation,we computed the proportion of the dark energy in the universe.And the obtained result that fits the observation and theoretical analyze is 74%.That means that the unverse is dominated by the dark energy.
