| 摘 要： | 新研制成功的、工作于液氮温度下的高临界转变温度超导量子干涉器(以下简写成为高Tc RF—SQUID),加上磁聚焦器之后,测量磁场的灵敏度已达10~(-12)T(10~(-(?)G).在国家地震局的零磁实验室中,我们用这样的RF—SQUID,初步地测得了与心脏跳动及手指动脉血流有关的人体磁信号.

| Abstract: | Operating in liquid nitrogen(78 K),with a magnetic focaliser, the magnetic measurement sensitivity of the RF-SQUID6] could reach 10-12T(10-8G). Using such RF-SQUID, in the magnetically shielded room constructed by the Chinese National Bureau of Seismology,the human magnetic signals relative to heart and arterial blood of finger have been detected preliminarily. |
