【摘要】 我们在１９９２年研制完成了ＭＤ－２型磁变仪数据采集记录系统，它在ＭＤ－１型的基础上进一步改进和增强了系统性能。ＭＤ－２型配接俄罗斯的磁变仪，已在南极和北京以及俄罗斯的部分台站投入使用。它的研制应用大大提高了地磁测量数据的质量和处理速度，实现了台站记录设备的更新换代。更多还原

【Abstract】 We developed the Type MD-2 data acquisition and recording system for the vari-ometer in l 992. Its properties are enhanced on the foundation of the Type MD I sys-tem. It connected with the quartz photoelectric variometer of Russia,and has been ap-plied in Beijng and Antarctica. In the meantime,the systems have been installed in theobservatories of Russia,such as ARTY,KASAN etc. The applications of the systemhave greatly improved the quality of the geomagnetic data and increased the processingrates. The systems have achieved the renewal of the recording instruments on the obser-vatory.更多还原
