等离子体的双流体模型描述了等离子体的磁性和流体方面之间的强耦合。贝尔特拉米条件,要求对齐的旋涡和流动成为一个系统的磁场和流速的联立方程。将这些方程组合起来就得到了双旋度贝尔特拉米方程。利用旋度算子的谱理论证明了方程的一般可解性。解的集合包含的场的组态可以与传统的常数-α-贝尔特拉米场(自然包含在集合中)有质的不同。更大的新集合可能有助于我们理解等离子体中产生的各种结构。
The two-fluid model of a plasma describes the strong coupling between the magnetic and the fluid aspects of the plasma. The Beltrami condition that demands alignment of vortices and flows becomes a system of simultaneous equations in the magnetic field and the flow velocity. Combining these equations yields the double curl Beltrami equation. General solvability of the equation has been proved using the spectral theory of the curl operator. The set of solutions contains field configurations that can be qualitatively different from the conventional constant-α-Beltrami fields (which are naturally included in the set). The larger new set may help us understand a variety of structures generated in plasmas.
