标题： On the Periods of Negative Superhumps and the Nature of Superoutbursts

摘要： Osaki和Kato（2012）将他们在矮新星V1504 Cyg中发现的负超振荡周期的变化解释为支持超爆发的热潮汐不稳定性模型的证据。 显示他们的解释是错误的。 回顾了观察证据，表明超爆发是由于质量转移率的增加。 显示英文摘要

摘要： Osaki and Kato (2012) interpreted variations of the negative superhump periods, discovered by them in dwarf nova V1504 Cyg, as evidence in favor of the thermal-tidal instability model for superoutbursts. It is shown that their interpretation was incorrect. The observational evidence is recalled showing that superoutbursts are due to the enhanced mass transfer rate.
