食双星系统AI Dra揭示了其轨道周期的变化。这些变化可以被描述为日食对与两个看不见的伴星围绕一个共同的质量中心运行的结果，周期分别为18年和43年，并且周期稳定增长。作者进行了14次新的极小期观测。
The eclipsing binary system AI Dra reveals changes of its orbital period. These variations could be described as a result of orbiting the eclipsing pair around a common center of mass with two unseen companions with the periods about 18 and 43 years together with a steady period increase. Fourteen new minima observations were carried out by the authors.
