飞越北极问题

The Problem of Flying over the North Pole

针对中美航线飞越北极建立数学模型 ,并根据地球的不同形状 (球体、旋转椭球体 )进行分析讨论 ,得出结论 :飞越北极 ,北京至底特律的飞行时间至少可节省

The present paper gives the problem of the airline between China and America across the North Pole. Afer a full discussion,a mathematics model is given,following mhich it can save at least 4 hours fhying from Bejing to Detroit.
