| 摘 要： | In this paper we show that Δ′B is negative over parts of the second region, and that plasmas are stable to Δ′B-driven resistive modes for realistic equilibria in which characteristics of finite-β configurations are retained. We have found that ideal instability is very sensitive to the ratio T=rΔ″/Δ′ in the second region. In comparison with previous works. results obtained by present authors show that the shift gradient Δ′ has a significant stabilizing effect on the second stable boundary, and this effect increases as the shear s becomes larger.
