中文摘要	The measurements of the microstructure, M(H) hysteresis and M(t) relaxation have been carried out on two types df melt-textured YBa2Cu3O7-y samples: stochiometic Y1.8Ba2.4Cu3.4Ox (Al) and Y1.8Ba2.4Cu3.4Ox + 0.05 mol%Pt (A2). It was found that the size of Y2BaCuO5 (Y-211) precipitates in A2 sample is smaller than that in Al sample; that the flux pinning potential depth U-00 in the A2 sample is much larger than that in the Al sample; and that the normalized relaxation rate S value of the A2 sample is lower than that of the Al sample. The results show that the reduction of the size of Y-211 precipitate can result in the increase of the flux pinning strength.
