terminal movement

The results show that this paper established by the manipulator path planning algorithm accurate and reliable, able to provide an effective manipulator movement path planning, and improve the artificial potential field of law can be effectively applied to the terminal space manipulator obstacle avoidance path planning.

仿真验证表明，本文所建立的机械臂路径规划算法正确可靠，能够对机械臂运动提供有效的路径规划，而且改进的人工势场法可以有效的应用于空间机械臂的末端避障路径规划。

However, the received performance of HF/ VHF communications is directly affected by Doppler frequency shift, which caused by transmission characteristics including terminal movement, fading, multi-path effects and other factors, thereby needs to be estimated accurately and compensated real-timely.

但是系统中终端的移动、衰落和多径效应引起的多普勒效应会严重的影响到接收性能。因此，准确实时的多普勒频移估计与补偿技术对于短波/超短波通信来说尤为重要。

Terminal movement causes channel fast fading, which makes channel estimation obsolete and influences receiver signal detection.

终端的移动会造成信道的快速时变，而使得信道的估计值产生偏差，因此影响对信号的估计。

In the terminal time of Yanshan movement, with orogeny finishing, extensional tectonic system developed from north to south.

燕山运动末期，秦岭地区造山活动结束，伸展拉张作用由北向南展开。
