1·The theoretical problems of the position feedback galvanometric recording system are systematically considered in this paper.

本文系统分析了位置反馈检流计式笔描记录系统。

2·At present, three kinds of seismographs are used at Chinese seismic stations. They are the direct-coupled seismometer, the galvanometric seismograph, and the electronic seismograph.

目前，我国基准地震台上使用三种类型地震仪：直接耦合地震仪、电流计记录地震仪和电子放大地震仪。

3·Instruments requiring the testing of Resolvers, Synchros, Galvanometric Movements and Lighting Circuits can be fully tested for operational performance in the Airborne Electrical Environment.

它对于需要做旋变，自整角，检流计的运动和照明电路测试的仪器，能够在航空电力环境里进行全面的使用特性测试。
