摘　　要：倾子是大地电磁测深方法的一个重要资料,到现在为止,该资料在生产中基本上没有被使用,原因是因为垂直磁信号十分微弱。随着高温超导量子干涉磁力仪在大地电磁测深中的应用,倾子资料将发挥其应有的作用。推导出基于半空间中球体的电磁响应的解析式,计算了均匀半空间中低阻和高阻埋藏球体的倾子的平面、拟断面和频率响应,分析了其特征和规律。对认识倾子的特性和开发利用倾子具有重要的指导意义。As a key parameter of magnetotelluric method, Tipper has not been used widely. Because the vertical component of magnetic field was quite weak, only a few researchers worked on it. The characteristics of tipper were not quite understood. With the advance of high TsSQUID magnetometer application. Tripper data are taken into full play . An analytic equation for electromagnetic response of semi-space sphere is derived. The areal, pseudo-sectional and frequency responses of low and high resisting buried sphere trippers in the even semispace are calculated, the characteristics and rules are analyzed. It is of great significance for guiding the tipper characteristic identification and its application.
