查询词典 radio

Radio telescopes are relatively inexpensive; radio signals travel at the speed of light, faster than which nothing can go; and the use of radio for communication is not a short-sighted or anthropocentric activity.

射电望远镜相对来说是昂贵的，无线电信号以光速行驶，没有什么比起它能走的更快了；而且无线电对于传播的使用不是一种短视或者以人类为宇宙中心的行为。

All provide a mixture of local news and comment, with some entertainment matter, mainly pop music, in between. In 1991 the Home Secretary appointed a new Radio Authority to take over the functions related to radio of the old IBA, and in particular to grant new licences to broadcast. In the 1990s there should be one or more new commercial radio stations broadcasting nationwide, including one 'non-pop' station, possibly for continuous broadcasts of classical music.

他们既提供地方新闻和评论，还插入一些娱乐节目，其中主要是流行音乐。1991年，内政大臣任命了一个新的广播公司，取代旧英国独立广播管理局的相关功能，尤其是为广播电台颁发新的许可证。20世纪90年代，一个或多个新的商业广播电台在全国范围内应运而生，包括一个"非流行音乐"台，用于长期播放古典音乐。

A Reflectional radio receiver also called a reflex radio is a radio receiver design in which the same amplifier is used for both the high-frequency radio RF and low-frequency sound AF signals .

一个来复收音接收机是这样一种收音机，它的放大器同时用来对高频信号和低频信号进行放大。

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.

通过对γ噪Blazar天体的谱指数、流量的相关研究，发现（1）51个样本blazar的γ射线光度与VLBI光度之间存在显著相关；（2）软X、硬X以及γ波段的观测谱指数之间存在较强的反相关，对FSRQs，无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献，而对于HBLs来说，则是同步辐射的贡献，对LBLs，在软X射线波段以同步辐射贡献为主，在硬X射线能区以逆康普顿贡献为主；（3）3C 273的射电各个波段以及光学之间存在强相关，高频辐射一直领先低频辐射，3C 273的多波段复合谱指数和高频流量之间存在强的反相关，意味着当能谱变硬时对象变亮。
