| 2. | Change caused by transients which , as a result of the modulation , are present in the transmission channel and depend on its transmission qualities
失真是由调制产生的瞬变引起的变化,存在于传输信道之中,并取决于它的传输质量。 |
| 3. | Change caused by transients which , as a result of the modulation , are present in the transmission channel and depend on its transmission qualities
失真是由调制产生的瞬变引起的变化，存在于传输信道之中，并取决于它的传输质量。 |
| 4. | Aal2 technology is much better than aal1 in the efficiency of bandwidth , especially according to the low rate operation , and could promise a good transmission quality
在带宽利用效率上，远远超过了aal1 ，尤其是针对低速率的业务，而且在传输质量( qos )上，基本上能得到保证。 |
| 5. | 4 . sms sender only provides the user with a means of typing short messages that will be transmitted by a cellular phone ; transmission quality is subject to the phone service provider
4 . sms sender只是为用户提供一种键入短消息的方式，而这些短消息是通过移动电话传输的；传输质量取决于电话服务提供商。 |
| 6. | Base on the reason mentioned above , the study and development of an intelligent system , which can measure and check the transmission quality of spiral bevel and hypoid gears , have important academic signification
因此，研究和开发一套锥齿轮智能检测系统具有一定的学术价值，建立锥齿轮传动智能综合检测系统具有重要的实际应用价值。 |
| 7. | Use dxx series transmission equipment to improve base station transmission quality of beijing mobile telephone network , including : equipment configuration , network structure , network management facility , and network synchronization scheme
利用dxx系列传输设备对北京移动通信的基站传输网进行了改进，包括：设备组成、网络结构、网管系统结构和功能以及同步时钟方案等。 |
| 8. | The system has been applied in the experimental sample , which has met all designing performance requirements with steady working performance on the condition of laboratory , high anti - interference ability and steady image transmission quality and is worthy of being promoted
制作的实验样机，达到了各项设计性能指标，在实验室条件下运行稳定，抗干扰能力较强，传输图像质量稳定，具有一定的应用价值。 |
| 9. | The combination of cablemodem and hfc is a way to revamp the catv network to a hybrid videodata communications network . however , hfc uses sub - carrier fdm , which requires ad conversion before transmission . in that sense , the transmission quality will be compromised
虽然cablemodem与hfc配合，是将catv网改造成为视频、数据混合通信网的一种可能选择，但hfc采用副载波频分复用方式，必须进行数模转换才能传输，所以传输质量将受到影响。 |
| 10. | However , since the fixed network is incomparably advantageous over its mobile counterpart in transmission quality , bandwidth and processing capability of the terminals , the www standards successfully used on the fixed network can not be used directly on the mobile network
但是，由于固定通信网络在传输质量、带宽、上网终端的处理能力等方面具有移动通信网不可比拟的优势，因此在固定网络上获得成功的www技术标准并不能直接应用于移动网络上。 |
