| 5. | Gene : well , earth is pretty noisy . we broadcast our presence in the universe twenty - four hours a day , with all our radio emissions 吉恩:因为地球太吵了。我们一天24小时用我们所有的无线电发射装置在宇宙里广播我们的存在。 |
| 6. | In chap . 1 of this dissertation , we introduce the background of solar activity , solar radio research and radio emission theory 作者在调研国内外太阳射电爆发研究的基础上,分析国家天文台射电望远镜观测到的bastille事件的射电爆发资料。 |
| 7. | So far there has been no success , but consider that even the earliest radio emissions from our civilization have only travelled about 50 light years into space , it may take some time before we hear the aliens , and they can hear us 虽然至今并无所获,但别忘记人类最早发出的无线电波,现时也只不过走了约50光年的距离,因此要收到外星人的讯息,可能还要一段时间。 |
| 8. | X - rays from chandra ( colored purple ) , optical and ultraviolet ( uv ) data from hubble ( red and orange ) , and radio emission from the very large array ( vla ) and merlin ( blue ) show how the jet from the main galaxy on the lower left is striking its companion galaxy to the upper right 钱德拉(紫色部分)的x射线,哈勃(红色和橙色部分)的光学和紫外线,以及vla和merlin射电图像显示在图左下方的主星系发出的喷流正击中乐在右上方的伴星系。 |
| 9. | Pulsar radio emission is markedly different from other astrophysical radio sources , characterised by extremely high brightness temperature and high degree of linear or circular polarization . the high brightness temperature of the pulsar radio emission implies that the underlying emission mechanism must be coherent . so far there is no widely accepted model for the radio emission . this paper discusses recent developments in studies of the production and propagation of pulsar radio emission 脉冲星的射电辐射与其他天体物理辐射源有很大的不同,因为它们有着极高的亮温度和高度的线或圆偏振.极高的亮温度意味着起作用的发射机制一定是相干的.至今尚无对这种辐射普遍接受的模型.本文讨论了关于脉冲星的射电辐射产生和传播研究中的新进展 |
