摘　　要：狮子AD(AD.Leo)是一个耀变十分频繁的耀星。本文通过对观测的分析,认为该星宁静期光度有高、低态之分,低态很可能是由大面积低温区引起的。AD Leo is a flare star displaying intense eruptive activities. Analysis of observational data-led us to suggest that the luminosity of this star during its quiescent phase may possess high and low states, and the low state is probably caused by a large area with a temperature lower than that of the rest of the stellar surface.
