查询词典 radio transmission

The data arrived on a radio signal so weak -- a ten quadrillionth of a watt -- that 38 giant radio antennas on four continents were used to catch Voyager's whispered message.

The behaviors of the driven field and radio field are studied in this paper and it can be seen that the forming of EIA or EIT and the whole probing properties are controlled by the Rabi frequencies of both driven field and radio field.

本文对新引进的驱动场的作用规律进行了重点研究，研究结果表明，当驱动场和射频场的Rabi频率满足不同关系时，系统呈现EIA或EIT两种不同特性，探测吸收曲线的整体轮廓也随之改变。

As we know, digital technique has gained the great development in the ages, and it can be found in almost every engineering science including radio astronomy and radio telescope technique.

在过去几十年里，数字技术取得了重大发展。在很多技术科学领域都能找到它的踪影，包括射电天文学以及射电望远镜技术。

Radio astronomy is different from most other forms of observational astronomy in that the observed radio waves can be treated as waves rather than as discrete photons .

射电天文不同于大多数其他形式的观测天文学中所观察到的无线电波可被视为波，而不是离散的光子。

您可以鹬第二和第三工会领袖从这一立场出发。

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。
