For the first time, we study the radio afterglow behavior during the trans-relativistic phase of the fireball shock wave. Considering the trans-relativistic shock dynamic and the synchrotron self-absorption effect of the relativistic electrons on the radio emission, we find that the dense medium model can not only explain the fast decline of the X-ray and optical afterglows of GRB980519, but also account for its radio afterglow quite well.

我们首次研究了致密介质情形下射电余辉在跨相对论阶段的行为，发现考虑到激波的跨相对论动力学和相对论电子的同步自吸收效应对射电辐射的影响，致密介质模型既可以解释GRB980519的快速衰减的X射线和光学余辉，也可以很好地解释其射电余辉的特点。

It is called a radio telescope because a radio antenna is used to observe radio waves emitted by astronomical sources.

它被称为射电望远镜，因为收音机的天线是用来观察天文活动所排放的无线电波。

Currently there are two kinds of cognitive radio: overlay cognitive radio and underlay cognitive radio.

近来的很多研究和测量表明，频谱拥塞重要是由频谱分配和使用的低效率导致的。

Article 16 The operating unit or operator of satellite communication networks shall abide by the laws and regulations of the State on radio administration, be subject to the supervision and inspection of the radio administration bodies, and cooperate with the radio administration bodies to manage the earth stations within the networks.

第十六条卫星通信网运营单位或经营者应当遵守国家无线电管理的法规、规章，接受无线电管理机构的监督检查，配合无线电管理机构对网内地球站进行管理。

That is to say, by using the special digital converter or running relevant arithmetic, it converts the radio signal to intermediate frequency signal and completes the base-band signal process that isn"t the veriest SR and is named "software defined radio. This paper introduces the rapid system prototype into the design of software radio system, which has great advantage because rapid system prototype technology can be used to describe the future application.

由于受到硬件性能如A／D、D／A及DSP芯片处理速度的限制，目前的软件无线电系统多采用折中的实现方案，增加专用的数字变频器或者运行数字变频算法，将射频信号变频到中频，然后再进行基带信号处理，这样的软件无线电系统又被称之为"软件定义无线电"，它并不是真正意义上的软件无线电。

The effect of endoscopic plasma radio-frequency therapy for gastrointestinal polyps is obvious and very safe, and bequite with high-frequency eletrosetion, plasma radio-frequency electrosetion could be used on special locations and excelled to the comparisonal group in therapic time,be good for clinical using as the preferred method to therapy for gastrointestinal polyps.Key words: polypus recti; endoscope; radio–frequency therapy; cutting

等离子射频技术应用于消化内镜下息肉切除，具有安全、疗效可靠，其疗效与高频电切相当，且能够在内镜反转状态针对胃底、直肠下段等特殊部位息肉实施有效切除，在术后愈合时间上明显优于对照组，可尝试作为内镜下切除消化道息肉的首选方法，对具有消化内镜诊疗条件的医疗机构，值得临床推广应用。
