本文叙述了实现高稳定旋转系统的必要性、遇到的问题及采取的措施。给出了获得高稳定旋转系统的装置以及获得的实验结果。给出了检测信号探头置于永磁缝隙之前,利用测速计方法测量,在实验中连续运转并测量10小时最大变化为0.60Hz,当此探头置于永磁的缝隙时,利用旋转边峰方法测量,同样连续运转并测量10小时最大变化为1.05Hz。并且给出在谱仪中应用这个系统获得的高分辨率NMR(核磁共振)波谱的最高分辨率可达0.2Hz。
This article describes the necessity, problems and measures to achieve a highly stable rotating system. The device for obtaining a highly stable rotating system and the experimental results obtained are given. Given the detection signal before the probe placed in the permanent magnet gap, the use of tachometer method to measure the continuous operation in the experiment and measured the maximum change of 10 hours was 0.60Hz, when the probe is placed in the permanent magnet gap, the use of spin-side peak method Measurements, same continuous run and measured 10 hours maximum change of 1.05 Hz. And gives a resolution of up to 0.2 Hz for high resolution NMR (nuclear magnetic resonance) spectra obtained using this system in a spectrometer.
