标题： Photometry of Three Superoutbursts of the SU UMa-type Dwarf Nova, SW Ursae Majoris

摘要： 我们研究了超级椭光的演化，分析了SW UMa在2000年2月至3月、2002年10月至11月以及2006年9月的超级爆发的光学光电观测。超级椭光在2000年和2002年的超级爆发出现后以相同的方式演化，2006年可能也是如此。这表明超级椭光的演化可能受恒定的双星参数控制。我们在2000年超级爆发结束后的光曲线中检测到了一个无相位偏移的周期性，这似乎是超级椭光的遗留。我们在2000年和2002年超级爆发的最后阶段发现了QPO（准周期振荡），但未能发现之前在SW UMa中观察到的被称为“超级QPO”的异常大振幅QPO。 显示英文摘要

摘要： We investigated the superhump evolution, analysing optical photometric observations of the 2000 February-March, the 2002 October-November, and the 2006 September superoutbursts of SW UMa. The superhumps evolved in the same way after their appearance during the 2000 and the 2002 superoutbursts, and probably during the 2006 one. This indicates that the superhump evolution may be governed by the invariable binary parameters. We detected a periodicity in light curve after the end of the 2000 superoutburst without phase shift, which seems to be the remains of the superhumps. We found QPOs at the end stage of the 2000 and the 2002 superoutbursts, but failed to find extraordinarily large-amplitude QPOs called `super-QPOs' which previously have been observed in SW UMa.
