传输

RS-485 is one of them used widely,it adopts second-differential balanced transmission and has a well immunity,it can control 32 devices and its longest transmissional distance is 1200m.its price is extrme low.

研究了各种控制总线，其中RS-485采用二线差分平衡传输，具有良好的抗干扰性，最大负载为32个，最远传输距离1200m，且价格比较便宜。

However,with the increase of well depth, complex architectual well and transmittable speed, the wired signal transmission is the inevitable development trends of intelligent drilling.

随着井深的增加、复杂结构井和欠平衡井的增多以及对传输速度要求的提高，电缆信号传输必然是今后智能钻井的发展方向。

Focusing on three key issues of the efficiency of video transmission, reliability and friendship on nets, the paper conducts a deep analysis of the enhancement of the compression of video-coding layer based on H.264, the optimized assembly of the net matching layer and the ability to correct errors of the decoder and encoder. Take the package switch of IP Video information package as an example, the thesis focuses on the reflection process of the Internet RPT/UDP/IP acted on by H.264, illustrates the typica...

围绕视频传输要求高效、可靠和网络友好的三个焦点问题，深入研究H 。2 6 4标准编码层压缩性能的提升、网络适配层的无缝集成和编/解码器的容错性能；以基于包交换的IP视频信息包为例，重点分析H 。2 6 4对因特网RTP/UDP/IP协议的映射过程；阐述H 。2 6 4在视频移动通信、视频流服务、数字电视广播与存储领域的典型应用特点；指出H 。2 6 4对视频源压缩、信道有效利用、缓解视频传输瓶颈的影响和发展前景。

The server or gateway must transmit the yielded strings to the client in an unbuffered fashion, completing the transmission of each string before requesting another one.

服务器必须将产生的字符串以一种无缓冲的方式传输到客户端，每次传输完一个字符串再去获取下一个。

The NetEvent class provides a foundation for guaranteed, guaranteed ordered and unguaranteed message transmission. NetEvent uses the same class instance creation mechanism as the console, but rather than instantiating by name, NetEvents use a class id, assigned when the console initializes.

NetEvent类提供了保证传输的基础，它保证了顺序和不保证的消息传输，NetEvent使用了和console同样的创建机理，但是它不是按照名字进行初始化，而是按照类id来进行，并当控制台初始化的时候得到赋值。

Simulative results show that the electron beam can be transported in the unmagnetized plasma-filled for two reasons. The first, the plasma neutralizes the majority of the space charge forces within the beam. The second, radial electric field generated by electron beam interaction with the plasma leads the beam to converge along axis. By PIC simulation, we find that atomic mass of the background ion effects on the Characteristics of the plasma-filled devices.

非磁化等离子体填充的RBWO-FEL的模拟表明只有在一较窄的背景等离子体密度范围内，电子注才能良好传输，产生泵波及激光功率输出，并都存在有峰值功率点，同实验观测到的结果完全吻合；该范围内，电子注的传输是由于背景离子中和了注中径向发散空间电荷力及注在等离子体中产生的径向的电场使注在轴向汇聚。

The simulation results also demonstrate the hole transport properties in unstrained and strained bulk silicon material, which will be shown in the next chapter. In chapter 4, a Monte Carlo method including a realistic valence band structure is developed to simulate hole transport properties.

在第四章中，根据前两章所得到的价电带结构，使用蒙地卡罗方法来模拟电洞的传输，其两种模型对电洞传输特性的影响可以由模拟结果得知。

The invention can transmit the bit flows which are different, unsynchronized and is different in transmission protocols, and can realize communication with high speed.

本发明可以使两个传输速率不同、不同步并且传输协议不同的比特流进行高速通信。

Like Cox, Sprague, and the cypherpunks, JEIDA counts on public-key encryption to keep these counts private and untampered as they are transmitted to the credit center. Peter Sprague says plainly,"Encrypted metering is an ASCAP for intellectual property."

和确斯，斯普雷格还有密码浪子们一样，他们也是把希望寄托在公共密钥的加密技术上面，希望这种加密技术可以让被传输的信息保持其私密性，不会被做了手脚，就像是向信用卡中心传输的那些信息一样。

There are two defferent design of hardware: optical fiber temperature sensor is used for middle-voltage Metal-clad switchgear, which data is transferred by optical fiber; another one is 1-Wire Digital Thermometer, it is used for lower-voltage Metal-clad switchgear, and the data is transferred by unwired.

硬件方面设计了两种不同的温度传感系统：中压开关柜过热故障监测采用光纤式温度传感器，同时采用光纤传输数据；低压开关柜采用单总线数字式温度传感器，数据采用无线传输。

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。
