摘　　要：介绍了用磁性法测定大型球罐残余应力方法 ,通过对 80 0 0 m3液化石油气球罐和 1 0 0 0 0 m3天然气球罐的实测 ,阐明采用该方法测定大型球罐残余应力的优越性。The magnetic method, by which the residual stresses in a large sized spherical tank are measured, is introduced. Through the practice in 8 000 m 3 LPG spherical tanks and 10 000 m 3 natural gas ones,the superiority of using this method to measure residual stress in a large sized tank is described.
