1. The 1960s and early 1970s were a time of change and turbulence. 20世纪60年代和70年代初期是个变革和动荡的年代。
2. The plane encountered severe turbulence and winds of nearly two-hundred miles an hour. 那架飞机遇到了强湍流和时速近二百英里的强风。
3. On the other hand, air turbulence increases because of the effect of skyscrapers on airflow. 另一方面,摩天大楼对气流的影响导致了空气湍流增加。
4. In zones of increased turbulence, the planes' wakes will decay more quickly and the effect will diminish. 在湍流增强的区域,飞机的尾流会消失得更快,它的效果也会减弱。
5. The cause appears to be in part greater turbulence in the urban atmosphere as hot air rises from the built-up surface. 部分原因似乎是热空气从楼宇密集的表面上升,造成城市大气的更大湍流。
