查询词典 radio scattering

Next, we reviewed the connection between RBLs and XBLs and the energy radiative process of BL Lacertae. Synchrotron radiation from radio to optical band and inverse Compton Scattering in γ ray wavebands are a wide accepted point. The beam model and gravitationally lensed model are two models associated with the radiative process. At present people tends to favor the previous one.

接着我们对射电选BL Lac型天体和X射线选BL Lac型天体之间的关系以及BL Lac型天体的能量辐射机制进行了评述，从射电到光学的同步辐射和γ射线波段逆康普顿散射的观点受到大家的普遍接受，射束模型和引力透镜模型是与辐射机制相关的两种模型，目前比较倾向于射束模型的解释。

ABSTRACT The electromagnetic scattering is an important research field in radio science and technology.

电磁散射是无线电科学和技术中的重要基础研究领域之一，在军事和国民经济的许多方面具有广泛的应用。

Radio Frequency Identification System BE make use of RF energy to deliver data,belong to a wireless communication technique,is 1 kind not the system of contact type,it constitutes the component contain the application system of the reader,electron label,Antenna,host computer, its induction method depends on passive type Tag with active type Tag distinguish analyse, can be divided into induction coupling and back scattering coupling and induced the coupling is the induction method (as 135 KHzs、13.56 MHzs) which belongs to low frequency、high frequency,the back scattering coupling is the induction method(as 915 MHzs、2.45 GHzs) which belongs to superhigh frequency,microwave, and what we construct apply system is use the high frequency 13.56 MHzs of induction coupling method.

中文摘要无线射频辨识系统(Radio Frequency Identification；RFID)是利用RF能量来传递资料，属於无线通讯技术，是一种非接触式的系统，其组成元件有读卡机、电子标签、天线、主电脑应用系统，其感应方式依被动式Tag和主动式Tag来区分，可分为感应耦合和反向散射耦合而感应耦合是属於低频、高频的感应方式(如135KHz、13.56MHz)，反向散射耦合是属於超高频、微波的感应方式(如915MHz、2.45GHz)，而我们所建构的应用系统是使用高频13.56MHz的感应耦合方式。

She gently rebuff ed him, but agreed that they could be friends
