论文摘要
平面对称Bianchi I模型被考虑使用恒定减速参数，$ q =α-1$，其中$α\ geq0 $。 $α= 0 $的模型在整个演变过程中违反了NEC，因此提供了一种身体上不切实际的情况。带有$α\ neq0 $的模型在后期遵守NEC和WEC，这表明在这种情况下，模型可以呈现出物理现实的宇宙学场景，尽管有限的时间。还表明，这两个模型的物理和运动学行为仍然与LRS Bianchi I模型相似。
A plane symmetric Bianchi I model is considered with constant deceleration parameter, $q=α-1$, where $α\geq0$. The model with $α=0$ violates the NEC throughout the evolution, and hence provides a physically unrealistic scenario. The model with $α\neq0$ obeys the NEC and WEC at late times, which shows that the models in this case can render a physical realistic cosmological scenario, though for a restricted period of time. It is also shown that the physical and kinematical behaviour of both models remain similar to an LRS Bianchi I model.
