But delays and inefficiencies in air travel are due in large part to an outdated traffic-control system that still relies on slow, ground-based radar stations and repetitive voice communication.

不过航空运输延迟和低效的主要原因还是过时的空中交通管制——一套依靠地面控制、反应迟缓的雷达站和不断重复的语音通讯建立起来的体系。

In the distributed multi-sensor multi-target information fusion system, the local sensors usually provide the respective tracks at the different rates with different communication delays.

在分布式多传感多目标信息融合系统中，由于每个局部传感器的采样频率不同以及具有不同的通信延迟，导致送入融合中心的局部航迹往往不是同步的。

There are uncertainties in the model of a teleoperation robot system and communication time delays in the communication channels between the master and slave robot.

遥操作机器人系统的通信通道中存在通信时延，而且机器人模型存在不确定性，以致可能造成系统不稳定和操作性能降低。
