为测量ЭГ-2.5静电加速器分析磁铁的磁场强度,1974年我们曾研制了一台晶体管核磁共振测磁仪。为适应操作的具体情况,这台仪器的主体部分和控制部分必须相距30余米,中间用电缆连接。经过几年的使用,证明该仪器工作稳定,性能良好,但仍为手动操作。由于物理实验的需要,有时要频繁测磁。这样,手动操作的工作量很大,影响加速 In 1974, we developed a transistor NMR magnetometer to measure the magnetic field strength of a magnet by measuring the ЭГ-2.5 electrostatic accelerator. In order to adapt to the specific circumstances of the operation, the main part and the control part of this instrument must be more than 30 meters away from each other with a cable connected in the middle. After several years of use, the instrument proved to be stable and performing well, but still in manual operation. Due to the need of physical experiment, sometimes we should measure magnetism frequently. In this way, the manual operation is very heavy and affects the acceleration
