查询词典 radio frequency

After transverse Zeeman effect is introduced to reduce the mode coupling, the laser could produce two orthogonal linear polarized components with 5MHz beat frequency. The effect of the magnetic field's direction to generation of the dualfrequency and the polarization property of the laser is investigated Based on theoretical study and experimental investigation to the beat frequency tuning character, a novel method for stabilizing the laser beat frequency is brought forward.

现代机械工业的发展使得机床、三坐标测量机等的运行速度已提高至1m/s，为适应这种发展趋势，本文研究了高频差（5MHz）激光干涉仪的光源、稳频和外差信号的处理等基本问题，建立了测量速度可达1m/s的高测速激光干涉仪，并对其在加工中心主轴热漂移测量系统和加工中心误差实时测量系统中的应用进行了研究。

Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to gamma-ray band, and is dominated by non-thermal process.

Ctive Galactic Nucleus is the hottest research on modern astrophysics. Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to γ-ray band, and dominated by non-thermal process.

GNs是近代天体物理学研究的热门课题，blazar天体是AGNs中具有极端物理性质的一个子类，它以大振幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

Finally, I'm hoping after the ten weeks of training they'll be able to make their own radio magazine programmes about their life in and around the Aylesbury Estate. People will be able to listen to these programmes on London Chinese Radio's website or get a free copy on CD from local libraries and Chinese or Vietnamese Communities Centres.

培训课程一共是十个星期，当整个培训课程结束的时候，他们将能够自己制作他们感兴趣的有关在Aylesbury生活的一些节目，到时大家可以在伦敦华语的网站上收听到这些节目，同时，我们也会把这些节目录制成CD电子广播杂志，并把它们摆放在当地图书馆，华人以及越南人社区中心，供大家免费获取。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
