摘要 用全天的超新星数据对能量条件进行了限制,比较了不同天空方向上的异同,并尝试将空间按距离分层分别进行能量条件的限制.通过对全天近2000颗超新星样本的分区域研究,我们发现在大尺度上超新星数据显示了较好的各向同性,但是非均匀性比较明显;超新星本动可能是导致能量条件遭到违反的重要原因. Energy conditions provide mode-independent bounds on distance behavior of cosmic sources as a function of red-shift.Supernovae data in the whole sky were used to constrain energy conditions in the context of standard cosmology.Data obtained for different direction and distance were discussed.
