- The program package is tested by simulated data with/without the application of white noises.It is also preliminarily applied to the reduction of optical positions of four extragalactic radio sources. 采用模拟数据对该程序进行了可靠性检验，并将该程序应用于4颗河外射电源的光学定位。
- Theoretical analysis on the analytic expression of space VLBI ground-space baseline time delay shows that a minimum number of 3 radio sources is necessary for GEDEX parameters adjustment. 对空间VLBI地-空基线时延的解析表达式分析表明，空间VLBI天文测地参数的联合平差要求每次实验至少观测3颗射电源。
- A powerful digital music radio source code, support for digital music broadcasting network. 一个功能强大的数字音乐电台源代码，支持数字音乐网络广播。
- Another is that ellipticals generally inhabit richer environments, providing a large-scale intergalactic medium to confine the radio source. 喷流和热点（见下文）是常见的高频同步加速辐射的来源。
- A transistorize radio takes no time to warm up. 晶体管收音机不需要预热时间。
- Kuwaiti radio source reported an attack last night resulting in a fire on one of the oil wells where the previous fire was just recently extinguished. 科威特一家电台报道，昨晚的一次攻击使一口油井起火，而该地以前的油井大火最近才被扑灭。
