标题： Multicolor photometry of SU UMa and U Gem during quiescence, outburst and superoutburst

摘要： 两年时间内对SU UMa和U Gem进行时间分辨观测的结果如下。 这两颗恒星分别是不同类 dwarf novae 的原型。 我们研究了不同时间尺度上的亮度变化：轨道周期、QPO和闪烁。 多色BVRI测光有助于区分这些变化的几何和物理来源。 显示英文摘要

摘要： The results of time-resolved observations of SU UMa and U Gem obtained over two-years are presented. Both stars are prototypes of different classes of dwarf novae. We studied brightness variations on different time scales: orbital, QPO and flickering. The multicolor BVRI photometry allows to distinguisch the geometrical and physical sources of these variations.
