摘要：

A functional form is presented for the efficiency of current drive in toroidal geometry with waves at frequencies below the electron cyclotron frequency. By fitting constants in order to duplicate numerical results for the efficiency, an accurate function is obtained which will be useful for computer calculations of current drive.
