The effectual transmission of information is the main research field of this thesis.

噪声和衰落是无线移动通信中影响可靠通信的两个主要障碍。

The memory arbitrator acts as an arbitrator when the protocol process and the MCU access the data buffer at the sametime.the UTMI interface is the analogy fronter of the USB2.0 interface.because the host controller deals with non-communication work depending on the MCU, it needs the MCU interface to connect the MCU.

其中协议处理模块负责处理所有的USB的数据的读写以及通信的控制，是整个主控制器的核心部分；数据缓冲区模块实现对接收或者发送的数据的缓冲处理；存储器仲裁模块解决协议处理模块和微控制器模块同时访问数据缓冲区模块的冲突问题；UTMI接口模块用作USB2.0接口的模拟前端；微控制器模块是与外部微控制器的接口，因为控制器除了要处理USB通信的工作，还必须依*外部微控制器来处理非USB通信的工作。

Steganography to hide the normal vector of communication, to cover up a secret communication behavior.

隐写将通信隐藏于正常载体中，从而掩盖秘密通信的行为。

The apparatus, which performs data communication with peripheral devices having an outdoor unit, a plurality of indoor units, a repeater and a wired remote controller, includes a level converter for serving as an interface to allow multiplex communication between the apparatus and the peripheral devices; and an abnormality detector connectable with the peripheral devices from a remote site through the level converter, the abnormality detector detecting a communication abnormality in the peripheral devices by automatically changing an operation mode thereof into a slave or master mode depending on whether an operation mode of each of the peripheral devices connected thereto is the master or slave mode.

所述装置执行与外围设备的数据通信，所述外围设备包括室外单元、多个室内单元、中继器和有线遥控器，所述装置包括电平转换器，作为允许在装置100与多个外围设备之间进行多路复用通信的接口；以及可通过所述电平转换器与远端的所述外围设备相连的异常检测器，所述异常检测器通过如下方式检测所述外围设备中的通信异常：取决于连接到所述异常检测器的每一个所述外围设备的操作模式是主动模式还是从动模式，自动地把所述异常检测器的操作模式变为从动或主动模式。

A communication system for passing information between information services and terminal devices over a twisted wire pair network.

一种通过双绞线网络在信息服务和终端设备之间进行通信的通信系统。

Telecommunications service means a service for carrying communications by means of guided or unguided electromagnetic energy or both.

通信服务指一个负载通信的服务–通过导通式电磁能或非导通式电磁能或两种方式兼具。

The rapid development of the mobile communication is taken for granted in the world. But I want to reach a conclusion by Poter's rhombus theory, the analysis theory in the industry competition, the base of GMCC's development and the acquisition analysis of the mobile...

移动通信业的高速发展状况是人所共知的，笔者主要想通过波特的菱形理论，行业竞争分析理论，广东移动通信发展基础的开发步骤，以及移动通信市场需求的分析等说明一种可能：就是通过移动通信的发展，加快电信服务普及化、社会信息化的进程，从而提高相关产业的发展，并带动其他行业的变革和提高，进而推动国民经济的发展，为实现中国在本世纪中叶赶上中等发达国家的目标而添砖加瓦。

Under large-scale environment and so on building underlying bed, underground market, underground parking garage, the mobile communication signal is weak, the handset was unable normally to use, has formed the mobile communication blind spot and the shadow region; In among floor periphery, because comes from different base depot signal overlapping, has the pingpong effect, the handset frequent cut, even falls the speech, seriously has affected the handset normal use; In building high level, as a result of the base depot antenna high limit, is unable normally to cover, also is the mobile communication blind spot.

在大型建筑物的低层、地下商场、地下停车场等环境下，移动通信信号弱，手机无法正常使用，形成了移动通信的盲区和阴影区；在中间楼层，由于来自周围不同基站信号的重叠，产生乒乓效应，手机频繁切换，甚至掉话，严重影响了手机的正常使用；在建筑物的高层，由于受基站天线的高度限制，无法正常覆盖，也是移动通信的盲区。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
