| 摘 要： | 本文介绍了利用在南极长城站接收来自ＲＷＭ（莫斯科）和ＲＩＤ（伊尔库茨克）台的授时信号的无线电波时延的测量方法，并依据１９９１年４月至１９９１年９月所测量的传播时延数据分析了电波传播路径。说明了沿长、短大圆路径的传播时段。判定存在着非大圆路径传播并阐明了关于非大圆路径传播的一些变化规律。对非大圆路径发生的条件进行了探讨

| Abstract: | In this paper the measurement method of radio wave propagation delay with the timming signals from RWM(Moscow) and RID(Irkutsk) station to Antarctic Great Wall Station is introduced. Then according to the propagation delay data measured from April 1991 to September 1991 the propagation paths are analyzed. The propagation time blocks along the long and short great circle paths are illustrated. It is recognized that there are non great circle path propagation, and its behaviour are explained. We make an approach to the occurrence condition for non great circle path propagation. |
