摘      要：The diffusion property of sulfur on the soda-lime-silicate float glass surface was studied by using secondary ion mass spectroscopy（SIMS）.According to the Fick＇s Second Law,two models of diffusion of sulfur on the glass surface were *** the diffusion of sulfate（S^6＋） is considered uniquely,the concentration-depth profile of sulfur can not be fitted very well,especially on the top surfaces of the air side and tin side of float *** the diffusion of sulfide（S^2-） on the profile of sulfur can not be *** concentration-depth profile of sulfur on both sides of glass can be fitted more exactly when both S^6＋ and S^2- are *** on the above-mentioned fitting results,it is concluded that the diffusion coefficents of S^6＋ and S^2- of tin side are larger than those of the air ***,the diffusion coefficents are related to the contacted medium.
