根据短距离截止与红外截止有关的思想，提出了一个全息暗能量模型。我们假设与暗能量相关的红外截止是视界的大小。在输入Omega(Lambda)=0.73的情况下，我们预测目前暗能量的状态方程为w=-0.90。在我们的设想中，宇宙重合问题可以通过膨胀来解决，只要我们假设电子折叠的次数最少。(C)2004爱思唯尔B.V.保留所有权利。
A model for holographic dark energy is proposed, following the idea that the short distance cut-off is related to the infrared cut-off. We assume that the infrared cut-off relevant to the dark energy is the size of the event horizon. With the input Omega(Lambda) = 0.73, we predict the equation of state of the dark energy at the present time be characterized by w = -0.90. The cosmic coincidence problem can be resolved by inflation in our scenario, provided we assume the minimal number of e-foldings. (C) 2004 Elsevier B.V. All rights reserved.
