5、开发蜂窝式移动电话系统并将其在许多城市中推广应用的原因之一是传统的移动电话系统存在容量有限、服务性能差、频谱利用率低的缺点。

One of many reasons for developing a cellular mobile telephone system and deploying it in many cities is the operational limitations of conventional mobile telephone system; limited servile capability，poor service performance，and inefficient frequency spectrum utilization.

6、来自发端借口不见的定时新号被加到数据调制解调器上，以使计算机与数传机同步。在接收端，从数据流中取出同步脉冲式计算机同步。

Timing signals from the interface assembly at the transmitter are applied to the data modem to synchronize the computer and the data set. At the receivers synchronization pulses are derived from the data stream to synchronize the computer.

7、我们正处于通信网络革命的开始，越来越大的容量需求，各种各样的应用，以及服务质量正在对光网络提出巨大的需求。

We are at the beginning of a revolution in communications networks, where increasing capacity, variety of applications, and quality of service are placing enormous demands on the optical network.

8、目前在欧洲正在开发第三代移动通信系统，其目的是要综合第二代系统的所有不同业务并覆盖更广泛的业务（话音、数据、视频、多媒体）范围，而且还要与固定电话网络的技术发展保持一致和兼容。

The third generation mobile communication system currently being developed in Europe, intended to integrate all the different services of the second generation system and cover a much wider range of broadband services (Voice、data、video、multimedia)consistent and compatible with technology developments taking place within the fixed telecommunication networks.

9、在现代对多媒体的描述中，我们所具有的技术已开始向人类具有的能力迈进；通过使用计算机技术、软件和其他技术，如CD-ROM。不仅能将视频图像和音频综合在一起，而且可以与其他计算机用户进行交互工作。
