Examples
- Sidereal rotation period
恒星日长度 - Yet the march 1979 burster , with an apparent rotation period of eight seconds , was spinning much more slowly than any radio pulsar then known
但1979年3月那次的爆炸源，看起来却有八秒的周期，自转速率要比当时所知的任何波霎还要慢得多。 - From the distribution of rotation period and convection parameter of m type stars , stellar chromospheric activity of m type stars depart from the anticipation of a . dynamo theory obviously
从m型主序星的自转周期的和恒星内部对流区随色指数的分布来看， m型主序星的色球活动行为与发电机理论的预期有明显的差异。 - We have collected a mass of stellar activity and rotation data of late - type stars . combining with the results of hipparcos satellite , we reserch the relation between stellar activity and rotation ( include rotation period and rossby number ) , and discuss the distribution of stellar rotation period and the evolution of angle momentum of late - type stars
因此，我们收集了晚型恒星的色球和冕球活动的指数以及恒星自转方面研究发表的大量的观测资料并结合hipparcos卫星的观测结果，对晚型恒星的磁活动与恒星自转间的相关性进行细致的研究。 - Though this departure is not obvious , the result still support the conclusion in the analysis of stellar chromospheric activity . for evolution stars , wo do n ' t , obtain significative result because the deficient samples . but the statistics analysis show the distrbution of corona activity of late type with color index and rotation period exist upper limit
演化恒星的磁冕球活动在色指数和自转周期的分布上都显示出冕球磁活动存在上限的现象，并且对冕球磁活动上限的拟合表明在色指数b一v为1 . 0附近和自转周期
