数值分析了高能捕获粒子对托卡马克气球模不稳定性的影响。利用变步长RKF积分方法成功地求解了一类微分-积分方程边值问题。数值结果表朋,气球模不稳定区随高能粒子压强增大而缩小,充分说明了高能捕获粒子能部分或全部抑制气球模不稳定性。
The effect of high energy trapping particles on the instability of tokamak balloon model is numerically analyzed. Boundary Value Problems for a Class of Differential - Integral Equations by Solving Variable - Step RKF Integral Methods. The numerical results show that the unstable area of balloon mode decreases with the increase of high-energy particle pressure, which fully shows that the trapped particles of high energy can partly or totally suppress the instability of balloon mode.
