%X With a given density profile of plasma,the temperature profiles of the plasma operating in the negative central magnetic shear mode,the H-mode and L-mode of conventional magnetic shear,are calculated respectively by applying the energy equation of electrons and ions,according to the thermal conductivity in different operational regimes.And then the electron cyclotron current drive and wave power deposition in the above modes are investigated with the relativistic Fokker-Planck equation incorporated into a ray tracing code.The result shows that in the mode of negative central magnetic shear,the current drive efficiency is the highest,meanwhile the zones of power deposition and current profile are wide.In the H-mode of conventional magnetic shear,the current drive efficiency is low,and the zones of power deposition and current profile are narrow.In the L-mode of conventional magnetic shear,the current drive efficiency is the lowest,the zones of power deposition and current profile are very narrow.
