But on Fridays Homs feels like a city under siege. Yellow plastic signs, rocks and dustbins are set up as roadblocks. Gunshots echo around the streets of restless neighbourhoods.
但是一到周五，整个城市就像遭到围攻一样，黄色塑料标志、石头和垃圾桶被堆成路障，枪声回响在发生骚乱的街区。
Although focusing on radar return data for "Echo Tops" and "Merged Reflectivity Composite" maps, these techniques are applicable to any set of planar images.
虽然主要关注“EchoTops”和“MergedReflectivityComposite”图的雷达返回数据，但是这些技术适用于任意一组平面图像。
The first echo line begins to set up the basic HTML you use to make the RSS feed human readable.

Call me when the fog set in. Sound regulation whistle, attend to echo sounding and start radar at an interval not more than 20 minutes.
下雾时要叫我，鸣放汽笛，动用测深仪，启动一次雷达不要超过20分钟。
The video signal model for synthetic aperture radar(SAR) is set up, and a method to generate echo signals for SAR using AWG520 arbitrary waveform generator is presented.
建立了合成孔径雷达回波视频信号模型，提出了一种用AWG520任意波形发生器生成SAR回波视频信号的方法，并用这种方法模拟了SAR实时成像的回波视频信号。
