This city is close to the fortieth parallel of North latitude. 这个城市靠近北纬40度。
In contrast, in the northern hemisphere, the lands lying above the sixtieth parallel of latitude include much of Scandinavia, Siberia and Alaska, all of Greenland and Iceland, with a total population of several million. 与之相对的北半球,北纬60度平行线以北区域,包括斯堪的纳维亚半岛、西伯利亚和阿拉斯加的大部分地区,以及格陵兰岛和冰岛的全部,人口总数几百万。

Thus the path of the vehicle mass center must be a circle around the axis, i. e. it must be a minor circle of the Earth, lying on a parallel of latitude. 所以飞行器质心的轨迹必须是围绕轴线的一个圆,即它必须是一个平行于纬度线的地球的小圆。
Those running around the world, parallel to the equator, are called lines of latitude. 那些国境线着地球,和赤道平等的线叫纬线。
