摘要
本文用Anderson的方法,利用Anderson,Margon等人的数据,重新分析和比较了进动不稳定性的正弦模型及阻尼正弦模型,并在此基础上提出了改进的进动不稳定性模型.最后,作了数理统计分析.结果表明,改进模型更好的描述了位相的变化.
In this paper, the sinemodel and damped sine model of precession instability in SS433 are analysed again through the da- ta from note,according to which a new damped sine model is advanced. The obtained conclusion of mathematical statis- tics shows that this new model is better than others.
