论文摘要
在热爆发宇宙学的背景下，预计目前低能中微子的宇宙背景与宇宙背景辐射的光子一致存在。宇宙中微子的数量密度与宇宙背景辐射的光子的数量相同。这使中微子成为宇宙中第二大最丰富的粒子物种。在早期的宇宙中，当这些中微子具有高度相对论时，它们在确定宇宙的最终结构和演变方面的影响很重要。
Within the context of hot big-bang cosmology, a cosmic background of presently low energy neutrinos is predicted to exist in concert with the photons of the cosmic background radiation. The number density of the cosmological neutrinos is of the same order as that of the photons of the cosmic background radiation. That makes neutrinos the second most abundant particle species in the universe. In the early universe, when these neutrinos were highly relativistic, their effects in determining the ultimate structure and evolution of the universe were significant.
