研究了给定等离子体通量下螺旋等离子体中径向电场的跃迁。密度梯度和温度梯度与径向电场一起被同时确定。如果除了新古典粒子通量之外还存在异常粒子输运，则电场表现出分叉的性质。基于麦克斯韦关于做功的构造，得到了分岔的临界条件。分岔的存在不受反常能流的影响。梯度被发现是在高等离子体通量制度的分叉。过渡到一个更好的约束进行了预测。梯度和电场的硬转变的存在表明电畴界面的存在，在电畴界面上梯度发生不连续的变化。
Transition of radial electric field is investigated in helical plasmas for the given plasma fluxes. The density and temperature gradients are simultaneously determined together with radial electric field. The electric field shows a nature of bifurcation, if an anomalous particle transport exists in addition to the neoclassical particle flux. Based on the Maxwell's construction with respect to the work-done, the critical condition for the bifurcation is obtained. The existence of bifurcation is not affected by the anomalous energy flux. The gradients are found to be subject to bifurcation at high plasma fluxes regime. The transition to a better confinement is predicted. The presence of hard transition of the gradient and electric field indicates the existence of the electric domain interface, across which the discontinuous change of gradient takes place.
