THE LINEAR THEORY OF THE LARGE-ORBIT ELECTRON CYCLOTRON MASER
大迴旋半径电子迴旋脉塞的线性理论

Making use of the perturbation approach, the large-orbit electron cyclotron maser is investigated. The perturbed motion of clectron and dispersion equation are obtain-ed, where gyrotron and gyro-peniotron are included. Then some discussions are car-ried out.
