  7. For a - early f type ms stars, stellar chromospheric activity decrease with stellar rotation period, but increase with rossby number ; for m type ms stars, stellar chromospheric activity increase with stellar rotation period and rossby number, and stellar chromospheric activity reach saturation at large color index ; for the ms stars between mid - f to m type, stellar chromospheric activity decrease with stellar rotation period and rossby number

    A ?早f型主序恆星的自轉周期和恆星對流區的隨色指數的分佈明顯地影響著這些恆星的色球活動行為。而m型主序星的色球活動水平基本上隨自轉參量的增大呈上升趨勢,並且m型主序星的色球活動水平在色指數較大時趨于飽和。
  8. It ' s the first time to explore the combustion characteristics of lpg / diesel mixing fuel engine, and find that, with the change of load and rotation, the changing trend of the ignition delay period of e10 mixing fuel is almost as identical as that of the diesel, but that of e30 mixing fuel is very different. comparing with diesel, the combustion of e10 is improved slightly, but that of e30 greatly changes ; the maximum eruptive pressure decreases ; the maximum pressure increase rate decreases ; the highest releasing heat rate increases ; the highest combustion temperature falls ; the ignition delay period extends

    結果表明: e10混合燃料與柴油的著火滯燃期隨負荷和轉速的變化趨勢基本一致; e30混合燃料與柴油則有所不同; eio混合燃料發動機的燃燒與純柴油相比,略有改善; e30混合燃料的燃燒特性發生明顯的變化,最高爆發壓力下降,最大壓力升高率減小,最大燃燒放熱率增大,最高燃燒溫度下降,滯燃期延長。
  9. 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,我們收集了晚型恆星的色球和冕球活動的指數以及恆星自轉方面研究發表的大量的觀測資料並結合hipparcos衛星的觀測結果,對晚型恆星的磁活動與恆星自轉間的相關性進行細致的研究。
