【摘要】 为了记录短周期地磁脉动,我们研制了81型照相记录感应式地磁脉动观测系统。该系统的最佳灵敏度为0.08γ/mm(T=10秒),周期范围大于4秒。经1981年夏季在漠河、北京、泰山、泉州所进行的联合观测,证明系统的性能是稳定的,各台记录资料有较好的对应性,并为地磁脉动的分析研究提供了我国第一批有意义的感应式地磁脉动仪记录。更多还原

【Abstract】 We have made a system of optically-recording induction magnetometer of 81-type, for micropulsation observations along Eastern Coast of China. The optimum sensitivity of this system is 0.08 #/mm (at T-10 sec) ; the range of the recorded period is above 4 sec. Through simultaneous observations at Mehe, Beijing, Taishan, Quanzhou along Eastern Coast of China in summer of 1981, the performance of this system is stable, and all data recorded at these four stations correspond very well.更多还原
