英文摘要	The Karolyhazy uncertainty relation indicates that there exists a minimal detectable cell delta t(3) over the region t(3) in Minkowski space-time. Due to the energy-time uncertainty relation, the energy of the cell delta t(3) cannot be less delta t(-1). Then we get a new energy density of metric fluctuations of Minkowski spacetime as delta t(-4). Motivated by the energy density, we propose two new dark-energy models. One model is characterized by the age of the universe and the other is characterized by the conformal age of the universe. We find that in the two models, the dark energy mimics a cosmological constant in the late time.
