The goal of a CSCW system is to enable users to cooperate conveniently no mater when and where While,currently,most CSCW users rely on existing network infrastructures Self organized Network is a multi hop temporary autonomous system of mobile nodes equipped with wireless transmitters and receivers without the aid of any current network infrastructure In such an environment,it may be necessary for one mobile node,in order to communicate another node,to need a chain of intermediate nodes to forward pac...

CSCW 系统目标是允许用户在任何地点，在任何时间可以方便地进行群体间的协同工作。目前大多数的CSCW 用户都需要依靠现有的网络基础设施。自组网是一组带有无线收发装置的移动节点组成的一个多跳的临时性的自治系统。在这种环境中，由于节点无线通信覆盖范围的有限性，需要借助其他中间节点进行分组转发到达信宿。它可以在没有可用的网络基础设施的情况下提供一种通信支撑环境，从而拓宽了CSCW 的应用环境。本文描述了自组网的概念和特点，并提出了自组网的体系结构。

L Transmitter and receiver is used in pairs in the same channel, and it is also allowed to use in one-many way in the same channel (one transmitter sends signal, several receivers receive in the same channel; it is synchronous and accurate to receive, which is equal to wireless video distributor), or it is also allowed to use in the many-many way (one transmitter occupies 1 channel, and supports 4 channels of video and audio transmission at the very most, which causes no cross fire one another).

l 发送器和接收器在同一信道内成对使用，也可在同一信道内以一对多方式使用（一个发送器发送信号，同一信道内多个接收器接受信号，实现同步精确接收，作用与无线视频分配器等同），或以多对多的方式使用（一个发射器占据一个信道，最多同时支持4信道的音频视频传输，互相不影响）。

The model simulations indicated that, when the outcrossing rate was no more than 1%, a 5 m buffer area with pollen receiver individuals between pollen donors and receivers was sufficient to minimize the frequencies of gene flow to .9%.

然而，对栽培水稻到其野生近缘种的基因漂移进行模拟的结果表明，栽培水稻到野生稻的基因漂移频率较高并且可能会对邻近的较大范围内的野生近缘种群体造成影响。

The 6V6-GT is a beam-power pentode designed for use in the audio-frequency power output stage of television and radio receivers.

是一支功率放大束射四极管，被设计用于电视机和收音机的音频放大功率输出级。

The former receivers randomly perform an arbitrary unitary operation on each of the particles, which is equivalent to eneryption of the particle with a random key and ensures the security of the present pro- tocol.

先前的接收者在每个粒子上随机地执行一个任意的幺正操作，相当于用一个随机的密钥加密粒子，确保了这个方案的安全性。

Transformer primary role is to transform voltage and switching current, such as tape recorders, TV receivers in the power transformer to play this role.

变压器的主要作用是变换电压和变换电流，如收录机、电视接收机中的电源变压器就起这个作用。

This feature is useful for designing optical sources and receivers of small radii.

这种特性对于设计光源和小半径接收器有用。

The most efficient and most common circuit for radio-frequency selection and amplification used in radio receivers is the superheterodyne.

最高效率和多数最共同的电路为radio-frequency 选择和放大作用被使用在无线电接收机是超外差收音机。

The error bit ratio performance formula for the block precoded OFDM system with zero forcing and squared error receivers in Rayleigh Raying channels is deduced in this paper.

推导了在瑞利衰落信道下的分组预编码正交频分多址调制系统，接收机采用迫零均衡和最小均方误差均衡的系统误码率公式。

At the rear was an innovative combination transaxle with the gearbox, clutch, differential, and inboard-mounted drum brakes.

在后面是与变速箱，离合器，差的创新结合变速，和内侧安装鼓式制动器。
