track carrier

Urban environment physique that the city history leave behind is a kind of special cultural carrier, noting the track of the city history.

城市历史发展遗留下来的建筑和空间环境，是一种特殊的文化载体，记录着城市历史演变的轨迹。

The land-based missile is designed to target and track aircraft carrier groups with the help of satellites, unmanned aerial vehicles and over-the-horizon radar.

路基导弹被设计为在卫星，无人飞行器和视距内雷达的帮助下定位和跟踪航母。

simulation results show that the method can track carrier frequency accurately and the feasibility of the method is validated.

仿真结果显示，该方法能够对载波频率正确跟踪，验证了算法的可行性。

Track roller , carrier roller, idler are mounted with long life well sealed-cone floating ring-floating ring seal.

支重轮、托链轮 、 引导轮均装有密封性能好、寿命长的浮动油封.
