In this paper a simple code has been developed to analyze power balance and qual-itatively evaluate current profiles for discharges with lower hybrid current drive (LHCD) and ionBernstein wave (IBW) heating in the HT-7 tokamak.Electron and ion thermal diffusivity,profilesof the bootstrap current density and total plasma current density can be estimated by this codeusing the experimental data.This code offers an easy and reasonable means to understand plasmatransport in HT-7.
