最近的研究表明，在Nflation中存在一个大的N相变，当场数足够大时，慢卷暴胀相将消失。在这篇简短的报告中，我们说明了Nflation的相图，并讨论了熵界和一些相关的结果。发现在临界点附近，场数使dS熵饱和。
Recently, it was showed that there is a large N phase transition in Nflation, in which when the number of fields is large enough, the slow roll inflation phase will disappear. In this brief report, we illustrate the phase diagram for Nflation, and discuss the entropy bound and some relevant results. It is found that near the critical point the number of fields saturates dS entropy.
