摘　　要：该文介绍一个高均匀度ＮｂＴｉ超导磁体的设计、制造和初步实验．超导磁体的内径为８８．６ｍｍ，在磁体中心空间１０×１０ｍｍ内，计算的磁场均匀度为１．７×１０（－７）．实验结果表明，在４．２Ｋ下，磁体经４次失超锻炼后中心磁场达８．７８Ｔ，该磁场超过３７０ＭＨｚＮＭＲ谱仪所需的８．６９Ｔ的水平。The design, conStruction and preliminary test of a highly homogeneous NbTi superconducting magnet with an inner diameter of 88.6mm are described. The computed field homogeneity of 1. 7 ×10-7 within the cylindrical space of 10mm in diameter and 10mm in height at the centre of the magnet has been achieved. The test results have shown that after suffering four training quenches the magnet reached a centre field of 8 .78Tat 4.2K. It exceeds the field requirement of 8 .69T for 370 MHz NMR spectrometer.
