摘要: 利用Z-80微处理机组成非闭环的负反馈自动匀场单元,实现了对F×90Q谱仪分辨率的自动调整和控制,分辨率稳定度达0.10Hz。适合各类PFT谱仪进行长时期累加实验。

Abstract: An autoshim derice with unclosed loop and rerersed feedback has been made up by using of microprocessor,thus the resolution of a FX90Q spectrometer could be automatically adjusted and controlled.The resolution stability is within 0.10Hz. It is adapted for long term accumulation in a variety of PFT-NMR spectrometer.
