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。

Even thinking of Fishing in the rever near my home, this is also my hobby, a person with a Yugan transferred to the radio favorite radio station, it is not listening to the CVC, the Australian radio that in the school i am unable to listen to.

这几天一直吃不下饭，还想吃吃家里做的饭菜。更想到家乡的那条河钓鱼，这也是我的爱好，一个人拿着鱼竿把收音调到最爱的电台，很就没有收听CVC了，那个澳洲电台，在学校一直没法收听，很想主播大为，红苹果，还有磊石。

In the second chapter, the author forecast the developing trend of trunked radio technology and makes the verdict that IP trunked radio technology will be a milestone of trunked radio technology in its developing history.

In a radio wave absorber (10), four hollow tetrahedrons (20) each of which has one open surface are connected such that a surface (20a) opposed to the open surface of the hollow tetrahedron (20) forms a side of a hollow pyramid (22). The radio wave absorber (10) is composed of a radio wave absorbing member shaped like a thin plate.

该电波吸收体(10)呈按照下述方式连接而形成的形状，该连接方式为将4个一面开口的中空四面体(20)以开口面相对的面(20a)作为中空棱锥(22)的侧面的方式形成。

Recent progress in radio prototype has extended the horizons of radio technology by liberating chronics dependence on hard-wired characteristics including frequency band, channel bandwidth, and channel coding. These efforts have led us to the feasibility of dynamically programmable receivers system of software radio.

软件无线电系统的硬件结构与功能相对独立，这样就可以基于相对通用的硬件平台，通过软件实现不同的通信功能，并可对工作频率、系统频带、调制方式等进行编程控制，系统的灵活性大大增加。

Based on a qualitative analysis of the data of the type IV radio burst and accompanying phenomena (post flare loops, radio pulsation in the decaying phase,multi-band emissions and mass ejection etc.)associated with the white light flare of 1991 June 6, it isproposed that the WLF and radio burst come from the sameelectron accelerating area in the low corona.

通过1991年6月6日共生太阳白光耀斑的射电运动IV型爆发及其伴随现象(包括耀斑后环、爆发衰减相的射电脉动、多波段射电辐射和太阳物质抛射等)观测资料的分析，定性地探讨了WLF的起源、加热机制和发射地点的问题。

The basic principle and optical telescopes are similar not only to receive light waves but the radio waves .1932 years Jansky first in the world to detect extraterrestrial radio waves, thus marking the birth of radio astronomy.

其基本原理与光学望远镜相似，唯接收的不是光波而是射电波。1932年央斯基在世界上第一个探测到地外射电波，从而标志着射电天文学的诞生。
