【摘要】 麦克斯韦理论为海底大地电磁探测技术奠定了坚实基础。大地电磁场的测量通常测取 Ex,Ey,H x,Hy,H z。大地电磁仪的设计要点包括 :高灵敏度、智能化、同步采集数据、锚系硬连接、承压密封和合理的下沉速度。所观测的数据经计算机处理后 ,可获得被测海域的地球物理信息更多还原

【Abstract】 Maxwell’s theory laid a solid foundation for MT decting technique. Ex, Ey, Hx , and Hy is generally measured in the marine MT prospecting. The design consideration of the marine MT instrument includes: high sensitivity, intelligentization, synchronous acquisition, connection of the anchor, pressure bearing and seal, and rational sinking speed. The geophysical information of the prospected marine field could be acquired by processing the data collected by the instrument.更多还原
