对耗散宇宙学的回顾支持了体粘滞的完全因果理论的应用。它表明，截断版本的这个理论导致，在许多条件下，病理行为的温度。讨论了粘性流体膨胀的物理一致性。给出了耗散de Sitter暴胀解，其中粘性比非因果或截断解低，且暴胀率不同。原则上，假设以大约6 × 10（33）s（-1）的速率进行大约60 e倍的暴胀，不需要重新加热就可以产生适当的熵。
A review of dissipative cosmology supports the application of the full causal theory of bulk viscosity. It is shown that truncated versions of this theory lead, under many conditions, to pathological behaviour of the temperature. The thermodynamical consistency of viscous fluid inflation is discussed. Dissipative de Sitter inflationary solutions are given, in which the viscosity is lower than for the non-causal or truncated solutions, and the inflation rate is different. It is possible, in principle, to generate the right amount of entropy without re-heating, given an inflation of about 60 e-folds at a rate of about 6 x 10(33) s(-1).
