摘要
本文用喷流模型计算SS433短周期变化的周期和振幅值。讨论短周期变化叠加成拍的条件.在理论上得出:SS433中可能存在红移拍,且在一个进动周期内其拍频为2。在实践方面,将观测资料进行数理统计分析,发现以上论断其置信度很高。
In this note,the periods and the amplitudes of the short period variations of SS433 have been cal-culated using the jet model.The conditions of beats,that occurs when these short periods variations su-perpose one another,have been discussed.Considering the conditions we are lead to the conclusion thatit is possible for the red shift beats to exist in SS433.From the jet model,the numbers of beats perpre-cessional period is 2.On the other hand,analyzing the observation data by means of mathematicalstatitics indicates the confidence level of above arguments is high.
