对称性自发破缺所诱发的种子平行雷诺胁强

根据第二类气球模理论，在托卡马克中诸如不稳定漂移波类的环形局部模将在径向呈现源于环形性的对称性自发破缺。以流体离子温度梯度模模型方程为例，解出在准环坐标系中由对称性自发破缺产生的二维局部模本征模式。在略去边带效应后，它成为具有径向位移修正的平板模式。由位移修正离子温度梯度模式导出了种子平行雷诺胁强，而它在传统的(无位移修正的)平板模式下被证明为零。

Seed parallel Reynolds stress induced by spontaneous symmetry breaking

The ballooning theory of the second kind anticipates the spontaneous radial symmetry breaking of unstable toroidal local modes in tokamak such as drift waves owing to toroidicity. Taking the fluid model equation of ion temperature gradient driven mode to be an instance, the two-dimensional local mode structure associated with the symmetry breaking is solved. When the sideband is neglected, it is reduced to the modified slab wave function by the radial shift. The modified slab wave function is used to yield the seed parallel Reynolds stress, which would otherwise (as in the traditional slab wave function) be zero.
