传输

In order to provide this kind of service,the wireless network must be able to support the different data transmission speed,in other words,in the room,outdoor and in the motion environment can support 2Mbps separately (a megabyte/each second),384kbps (a kilobyte/each second) as well as the 144kbps transmission fast.

为了提供这种服务，无线网络必须能够支持不同的数据传输速度，也就是说在室内、室外和移动的环境中能够分别支持2Mbps、384kbps以及144kbps的传输速度。

It is superior to automatic meter reading system of power line carrier system, it is characterized by features which are not to build new communication network, more accuracy transmitting kilowatt-hour meter data, and no restriction on region, space,time and distance, and realize point-to-multipoint data transmission.

该系统优于目前电力行业广泛使用的载波方式自动抄表系统，其特点是：不需另建新的网络传输系统，数据传送实时性强，不受地域、空间、距离、时间的限制，可进行一点对多点的数据传输。

In this paper, the propagation and focus properties for several modes describing hollow beam are analyzed, and the focus properties for hollow gaussian mode are particularly discussed. Furthermore, a new mode, high-order Bessel-Gauss mode, is put forward to describe hollow beams. The results for high order Bessel-Gauss beams propagating through lens focusing system and free space are derived by terms of Collins integral formula.

本文分析了几种描述空心光束数学模型的传输特性和聚焦特性，着重讨论了描述非中空光束的数学模型的聚焦特性；同时提出了一种描述完全中空的空心光束的新模型――高阶贝赛耳高斯模型，并且运用Collins积分公式，分析了这种新模型的空心光束的传输特性和聚焦特性。

The combination of Generalized Likelihood Ratio Test and Antenna Selection is applied to Unitarysignal transmission system, and antenna selection and signal detection do not require Channel State Information.

摘要该文提出了多天线传输系统的非相干天线选择算法，将广义似然比检验与天线选择结合应用于U码传输系统，天线选择和信号检测无需信道状态信息。

Liman, who joked about doubting his decision to appear at MIT, where the technology in his movie could be ripped apart, said he tried to find a source of reality in the science behind teleportation.

李曼开玩笑说，也许跑到MIT来是个错误，因为在这里他片中的心灵传输理论会被批得体无完肤，他说他试图为心灵传输的科学性寻找现实依据。

Clock recovery is the key for synchronization of MPEG-2 transportation over network. The PCR delay jitter is the main issue for clock recovery by PLL system.

时钟恢复是MPEG—2在网络上传输的同步关键，MPEG—2的标准建议采用PLL在本地恢复编码器的时钟，而PCR传输延迟抖动是PLL进行时钟恢复的主要问题。

The results show that the system can provide up to 54 Mbps transmission speed and superior anti-jamming capacity.

分析结果表明，Turbo-OFDM系统可以提供54Mbps的传输速率，并且具有较强的抗干扰特性，适合于UAV系统中高速数据传输。

They offer secure, 128-bit encrypted data transmission of up to two miles at 54 Mbps.

他们提供安全的， 128位加密的数据传输，以高达54 兆比特每秒的速度传输达2英里。

Running at one megabit per second with Manchester encoding, this Ethernet standard operates on a baseband basis, providing for a single transmission at a time. Connection to the centralized hub is accomplished over UTP of 22, 24 or 26 gauge at distances of up to 500 meters in a star topology. Two pairs are used, with one providing upstream connectivity to the hub and the other providing downstream connectivity.

该以太网标准属于基带传输，单工工作方式。1Base-5与中央集线器的联接是通过UTP完成的，UTP的规格为22，24和26，采用星型拓扑，最大传输距离为500米。1Base-5使用2对UTP，1对提供与HUB的上行连接，另1对提供下行连接。

And in fact, that decay-time lengthened, it equate to meson- decay physical course velocity change.

相对于光传输就是光速度的改变，就是光传输这一物理过程的速度的改变。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
