We discuss the prospects of constraining the properties of a dark energy component, with particular reference to a time varying equation of state, using future cluster surveys selected by their Sunyaev-Zel'dovich effect. We compute the number of clusters expected for a given set of cosmological parameters and propogate the errors expected from a variety of surveys. In the short term they will constrain dark energy in conjunction with future observations of type Ia supernovae, but may in time do so in their own right.
我们讨论了利用基于其苏尼亚耶夫-泽尔多维奇效应选择的未来星系团巡天来限制暗能量成分性质的前景，尤其涉及状态方程随时间变化的情况。我们计算了给定一组宇宙学参数下预期的星系团数量，并传播了各种巡天预期的误差。短期内，它们将与未来Ia型超新星的观测一起限制暗能量，但最终可能仅凭自身做到这一点。
