| 摘 要： | 本文概述了为青藏科考大地电磁测深工作研制的三分量磁饱和式磁力仪的原理、性能、用途和野外使用情况。 仪器的技术指标为:分辨率0.2伽（亻马）;灵敏度100毫伏/伽（亻马）;温度系数l伽（亻马）/℃;记录频带0-1.0赫兹;耗电量18瓦。 在青藏高原的地球物理考察中,用本仪器先后在藏南、藏北五个点进行了连续数月的野外地磁测量。从工作情况看,仪器工作正常,记录了一次完整的磁暴,为研究青藏高原地壳与上地幔的电性结构提供了一批有意义的资料。

| Abstract: | This paper gives a brief account, of the principle, performance and usage of the three-component flux-gate magnetometer for electromagnetic deep sounding in Qinghai-Xizang plateau.The technical specifications of the instrument are as follows: the resolusion is 0.2 γ, sensitivity is l00mV/γ; temperature coefficient is 1γ/℃; recording frequency band is 0-1.0 Hz; power consumption is 18 W.The instrument has been used for continuous field observations in five localities in the north and south of Xizang. A complete recording of a magnetic storm was obtained during the period of survey which showed that the instrument was satisfactory. |
