Satellite in elliptic orbit has a low velocity near apogee and will flight over a particular geographical area for a substantial part of its orbital period ("apogee dwell").

由于运行于椭圆轨道上的卫星在其远地点附近有较长的停留时间，如果选择轨道远地点位于覆盖区域上空，则采用椭圆轨道卫星星座以进行区域性覆盖以取得很好的覆盖效果。

In the meantime the Chinese air force's combat capability has also been greatly enhanced and the Sino-Soviet pilots in a number of air began to fight side by side.

在此期间，中国空军的作战能力也大大增强了，中苏飞行员在许多空战中开始并肩作战。1951年10月24日，34架美国飞机轰炸顺川大桥，中苏空军共40架米格飞机同时起飞迎战，击落美国1架F—84战斗机和1架B—29轰炸机。10月30日，56架处于战备状态的中苏两国米格—15飞机在清川江上空迎战由21架B—29飞机和200架护航战斗机组成的美国机群，击落12架B—29飞机和4架F—84飞机。

Many colleges have their own choirs whose singing wafts from college chapels at evensong or Sunday services, a celestial sound that causes even the staunchest agnostic to stop.

The cause of the heat-wave during the drought is the intensified Rossby wave over the Eurasia continent,which results in a closed warm anticyclone over the drought area,then an adiabatic warming is caused by the strong sinking motion.

华北地区夏季热浪天气的成因：(1)夏季欧亚大陆Rossby长定波波列的维持并发展，使得干旱区域上空出现闭合暖性高压系统，其强烈下沉运动引起空气绝热增温(2)局地干旱维持与发展使得干旱区内潜热大大降低，近地面感热以及向上长波辐射的增加使得干旱区域气温持续升高。

IT IS 2008, and an enormous, gloriously hued dragon balloon, symbolising China's tradition and virility, winds around the Olympic Stadium in Beijing.
