摘　　要：Electron heat diffusivity inferred from the electron power balance was studied in the ohmically heated plasma on an HT-7 tokamak.The results obtained before and after siliconization were compared and it is found that the diffusivity is reduced obviously in the half of the outer region(r/a>0.5)after siliconization,which was the reason why energy confinement was improved after siliconization.
