本文从状态发现者的观点研究了Li提出的全息暗能量模型。我们在statefinder参数平面中绘制了c = 1的模型的演化轨迹。状态发现图描述了全息暗能量的特性，并显示了这种情况与其他暗能量模型之间的区别。我们还对全息暗能量模型在不同c的情况下进行了状态发现者诊断，这是由三个观测数据拟合得到的。结果表明，从状态发现者的角度来看，c在该模型中起着重要的作用，因此应通过未来的高精度实验来认真确定。
In this paper, we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with c = 1 in the statefinder parameter-planes. The statefinder diagrams characterize the properties of the holographic dark energy and show the discrimination between this scenario and other dark energy models. We also perform a statefinder diagnostic to the holographic dark energy model in cases of different c which given by three fits to observational data. The result indicates that from the statefinder viewpoint c plays a significant role in this model and should thus be determined seriously by future high precision experiments.
