反弹暴涨成功解决了暴涨无法解决的奇点问题。一般地，该模型反弹区域持续时间较短。着重讨论宽反弹情形，并研究宽反弹期间的引力波功率谱。
The bounce inflation is successful in solving the initial singularity problem of inflation and is also competitive in explaining the power deficit in CMB at large scale. Generally, the duration that the bounce lasts is short (the so-called narrow bounce). However, the case of broad bounce is not ruled out. In this study, we focus on the tensor perturbation during the inflation with a broad bounce. We find that the power spectrum may be very different from that in narrow bounce model.
