- The description of space VLBI Geodesy Demonstration Experiment (GEDEX) is presented, and the singularity problem arisen from geodetic space VLBI observations of a single radio source is discussed. 介紹了測地空間VLBI論證實驗(GEDEX)的觀測方案、預期目標和已獲得的實測資料概況, 並對測地空間VLBI單源觀測導致的奇異性進行了理論分析和數值檢驗。
- The candidate catalog of radio sources for VLBI geometry network composed of Shanghai, Wulumuqi and Kunming is presented in this paper. 針對我國VLBI觀測網對射電源的特殊要求,給出了現有備選射電源的列表和天球分布圖,提出了擴充備選射電源數量的必要性。
- These formed shortly after the universe began and they came to the attention of earthling astronomers because quasars are powerful radio sources. 它們緊隨宇宙伊始而形成,並因類星體是巨大的無線電波發射源而進入天文學家的視野。
- Radio sources were divided by Fanaroff &Riley (1974) into two classes, now known as Fanaroff and Riley Class I (FRI), and Class II (FRII). 來自電波喧噪活躍星系的電波發射是同步加速輻射,被臆測是非常平滑的、自然的寬頻和高度偏振。
