摘要：
The expressions of both the Fisch–Boozer and Ohkawa currents are constructed, and a feasible and efficient calculation method is given. Simulation results of the Fokker–Plank code verify the expressions and the calculation method. We calculate and separate the Ohkawa and Fisch–Boozer currents on a single magnetic flux surface of the off-axis position. The Ohkawa current drive mechanism can be made dominant over the Fisch–Boozer mechanism to achieve a high driven current. This can be done by adjusting the parameters of electron cyclotron waves to make...
