接收端

When the distant computer answers with a higher pitched "carrier tone," you place the telephone handset in the acoustic coupler and transmit and receive data.

当远端计算机发出一个更高音调的"载波音"作为应答时，你将电话听筒放在声音耦合器上并开始发送和接收数据。

Due to the asynchronous serial communication port to send data in a line at the same time another line to receive data.

由于串口通信是异步的，端口能够在一根线上发送数据同时在另一根线上接收数据。

Send and receive news : you can set ports, baud rate, parity and other parameters.

通过设置发送并接收消息：可以设置端口，波特率，奇偶校验等参数。

At the rest of this paper, the following information are given: introduction to the variation of user status on the server; process of dynamic modifying to rule of packet filtering; the application of design patterner in implementation of rule table of packet filtering.

同时，本文还详细地介绍了使用原始网络插口技术接收和发送网络数据包的技术，客户端服务器端之间加密通信实现的过程，使用设计模式技术保证包过滤规则列表的唯一性等一些该方案在具体设计和实现中涉及的技术、问题和解决方法。

The method includes following steps:(1) initial frequency selection;(2) based on modulation mode adopted, the sending end carries out symbol mapping, changes signal spectrum based on label information of sub channel, and sends signal in time domain;(3) based on label information of sub channel, the receiving end carries out equalization for received signal, demodulates signal and accomplishes judgment;(4) carrying out channel estimation or prediction, the receiving end obtains updated information of signal state, and determines whether label information of sub channel is needed to update based on self-adapting judgment rule.

本发明提供了一种移动宽带信道中的自适应选频分块传输方法，该方法包括以下步骤：(1)初始选频；(2)发端根据所采用的调制方式进行符号映射，根据子信道标记信息改变信号频谱，并发送时域信号；(3)收端根据子信道标记信息对接收信号进行均衡，解调信号并完成判决；(4)收端进行信道估计或预测得到更新的信道状态信息，根据自适应判断规则，判断是否需要更新子信道标记信息。

And the PC in the remote end was in charge of incepting the data which were transmitted by the monitoring equipment through internet based on GPRS network, portraying the real-time track of the locomotive the vehicular spray equipment according to the data of longitude and latitude, displaying correlative data on PC's screen and saving them to the hard disk.

远端的PC机负责接收监测端利用GPRS网络通过Internet发过来的数据，然后根据其中的经纬度数据画出车载喷雾器的实时运行轨迹，在PC的显示器上显示相关的喷雾量数据，并将数据保存到PC机的硬盘中。

The client incepts data from Multimedia equipment and sends to the server.

客户端连接多媒体设备接收数据并发送给服务器端。

In the "rules of the name" field enter the name of this rule (such as BT to download the Rules);"Rule Description" column is here to fill out a detailed description of this rule can not be filled in; in the "other side's IP address" Select "Internet of any address";"the direction of data transmission," Please select "receive or send";"data protocol type" column of course, choose "TCP packet type"; in the "local port" in the fill from 688-6889, so that we designated the BT download software used by all ports, rather than to set up a separate one.

在&规则名称&栏中填入此规则的名称；&规则描述&一栏则是在此填写对这一规则的详细描述，可以不用填写；在&对方的IP地址&中选择&互联网任何地址&；&数据传输方向&请选择&接收或发送&；&数据协议类型&一栏中当然选择&TCP 类型数据包&；在&本地端口&中填写从688到6889，这样我们就指定了BT下载软件所使用的所有端口，而不用单独一个个去设置。

On the hardware electric circuit, uses MAX232 torealize PC machine and between the monolithic integrated circuit leveltransformation, uses the simple 3 systems connection methodrealization correspondence, soon PC machine and the monolithicintegrated circuit transmission data end and the receive data endcross connection, two groundings direct are connected; In the softwareprogramming, on PC machine was uses the existing string mouth to debugassistant software, the monolithic integrated circuit carries on theprogramming using the assembly language.

在硬件电路上，采用MAX232实现PC机与单片机之间的电平转换，采用简单的3线制连接方法实现通信，即将PC机和单片机的发送数据端与接收数据端交叉连接，两者的地线直接相连；在软件编程上，PC机上是采用了现有的串口调试助手软件，单片机则利用汇编语言进行编程。

An overladen buffer decreases the probability of the client buffer's underflow, however, it also introduces more significant end-to-end latency.

过分的缓冲尽管能够降低接收缓冲的下溢概率，但是却会导致更多的端到端延迟。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
