rossby number meaning in English
罗斯贝数
罗斯比数
Examples
- The following results are obtained : ( 1 ) the flow in rotating helical pipes are affected by dean number , curvature , torsion ( or germano number ) , the ratio of the coriolis force to the centrifugal force f number ( or rossby number ) and the geometry of the cross section
研究结果表明： ( 1 )旋转螺旋管道流动特性受dean数、曲率、挠率(或germano数) 、科氏力与离心力之比f数(或rossby数)以及截面的形状五种因素的影响。 - 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。 - 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型主序恒星的自转周期和恒星对流区的随色指数的分布明显地影响着这些恒星的色球活动行为。而m型主序星的色球活动水平基本上随自转参量的增大呈上升趋势，并且m型主序星的色球活动水平在色指数较大时趋于饱和。
