In the standard Friedmann-Lemaître-Robertson-Walker (FLRW) cosmological model, the energy conditions provides model-independent bounds on the behavior of the distance modulus. However, this method can not provide us the detailed information about the violation between the energy conditions and the observation. In this paper, we present an extended analysis of the energy conditions based upon the entropy density of the universe. On the one hand, we find that these conditions imply that entropy density $s$ depends on Hubble parameter $H\left(z\right)$. On the other hand, we compare the theoretical entropy density from the conservation law of energy–momentum tensor with that from the energy conditions using the observational Hubble parameter. When we consider a FLRW universe, according to the theoretical prediction, OHD, thermodynamics and several independent cosmological probes, show that the dominant energy condition is fitter than other energy conditions.

在标准Friedmann-Lemaître-Robertson-Walker（FLRW）宇宙学模型中，能量条件为距离模量的行为提供了与模型无关的界限。但是，这种方法无法为我们提供有关能量条件与观测值之间冲突的详细信息。在本文中，我们根据宇宙的熵密度对能量条件进行了扩展分析。一方面，我们发现这些条件暗示着熵密度$s$ 取决于哈勃参数 $H（ž）$。另一方面，我们使用观测的哈勃参数比较了能量动量张量守恒定律和能量条件下的理论熵密度。当我们考虑FLRW宇宙时，根据理论预测，OHD，热力学和几个独立的宇宙学探针表明，主导能量条件比其他能量条件更适合。
