| 1. | The glowing sunspots are the source of magnetic activity . the giant loops they generate collapse down violently , forming the turbulent space weather 太阳黑子不断增加最终产生太阳风暴,太阳风暴又形成恶劣的太空天气。 |
| 2. | It may be disruptive , but scientists believe that the intense magnetic activity on the surface of the sun was crucial in the formation of our solar system 剧烈的运动使太阳看起来似乎要爆炸了,但科学家相信,太阳风暴对太阳系的形成有至关重要的作用。 |
| 3. | In time periods shorter than a century , the most striking influences caused by the sun are associated with its magnetic activities such as flares and prominence 在一个世纪或以内的短时间内,太阳对地球的影响主要来自耀斑和日珥等太阳活动所造成的磁场变化。 |
| 4. | For the evolution stars with age less than 109 years , stellar magnetic activity and rotational period decrease with stellar age ; for the stars with age larger 而晚型演化恒星不论是演化恒星的磁活动还是自转周期以恒星年龄10 ”年为分界点表现出随年龄不同的规律。 |
| 5. | There have good linear relativity between stellar magnetic activity , rotational period and stellar age of ms stars , but this relativity of evolution stars has different action 在第七章中,我们讨论了晚型恒星的自转周期的分布、恒星年龄对晚型恒星磁活动的影响以及晚型恒星的角动量演化。 |
| 6. | Several explanations have been proposed , including cycles of magnetic activity somewhat similar to our own sun ' s sunspot cycle , the action of companion stars orbiting around the dying star , and stellar pulsations 现在有几个被提出的解释,包括像我们自己的太阳黑子周期的磁场周期活动,围绕衰老的恒星轨道有规律运动的伴星。 |
| 7. | Those inflexion are brought by the energy balance and heating mechanism in stellar chromosphere and corona . using large samples , we gain several credible numeric relation between different magnetic activity index and rotational parameters 我们通过对大样本恒星的统计分析分别得到了晚型主序星磁活动与恒星自转参量间以及磁活动与恒星色指数之间更广泛意义的数值关系。 |
| 8. | Characteristics of variation and disturbances in low - latitude ionosphere were investigated based on the data observed in hainan under different magnetic activities and solar activities including variations and disturbances of parameters in different ionospheric layers , behaviors of plasma drift and a comparison with other low - latitude ionospheric station . the disturbance propagations from high to low latitude region during magnetic storm time are also investigated with analyzing the data obtained from the east - asian high - middle latitude stations 本文在观测数据分析的基础上研究了不同地磁活动和太阳活动条件下低纬电离层的变化和扰动特性,包括海南电离层各分层的参数变化和扰动特性,电离层漂移的变化特性,并与低纬度地区其他台站进行了对比分析,还对暴时东亚地区高中纬度地区台站的观测资料进行了分析,研究了电离层扰动从高纬到低纬的响应过程。 |
