摘要
本文简述了无定向磁强计、感应线圈磁强计、质子磁强计、光泵磁强计、磁通门磁强计、超导量子磁强计等几种弱磁场测量仪器的特点和现状，重点评述了磁通门技术、高温ＳＱＵＩＤ技术等的最近发展，介绍了弱磁场测量技术的典型应用．
The state-of-art and general features of instruments for measuring weak magnetic fie-lds (such as the nondirectional magnetometer, induced coil magnetometer, proton magneto-meter, optical pumping magnetometer, flux-gate magnetometer and superconducting quantum magnetometer) are briefly described. Emphasis is laid on the development of a novel tech-nique used in the flux-gate magnetometer and the liquid nitrogen SQUID. Typical applica-tions of the measuring techniques for weak magnetic fields are given.
