iPTF14hls is an unusually bright, long-lived II-P supernova (SN), whose light curve has at least five peaks. We propose that the outflows from the black hole hyperaccretion systems in the center of the collapsars should continuously inject into the envelope. For a jet-driven core-collapsar model, the outflow feedback results in prolonging the accretion timescale and fluctuating accretion rates in our analytic solutions. Thus, the long period of luminous, varying SN iPTF14hls might originate from the choked jets, which are regulated by the feedback of the strong disk outflows in a massive core-collapsar. One can expect that jet-driven iPTF14hls may last no more than approximately 3,000 days, and the luminosity may quickly decrease in the later stages. Moreover, the double-peak light curves in some SNe might be explained by the outflow feedback mechanism.

iPTF14hls是异常明亮，寿命长的II-P超新星（SN），其光曲线至少有五个峰值。我们建议从坍塌中心的黑洞高积层系统流出的水应连续注入包膜中。对于喷气驱动的核心-collapsar模型，流出的反馈会导致我们的解析解决方案中积聚时间尺度的增加和积聚速率的波动。因此，长时间的发光，变化的SN iPTF14hls可能来自阻塞的喷流，而阻塞的喷流受大型核心-collapsar中强大的磁盘流出的反馈的调节。可以预期，由喷气驱动的iPTF14hls可持续使用的时间不超过大约3,000天，并且在以后的阶段中，亮度可能会迅速下降。此外，
