对于弱剪切或反向剪切在内部输运屏障形成中的作用存在一些争议。一种理论将内部输运屏障的形成归因于最小q区全球波结构的间隙。结果表明,在一般情况下不存在这样的间隙,并且能量输运是平滑的,并且在这样一个最小q区域内能量输运是增加的。
Some controversy exists over the role of weak or reversed shear in the formation of internal transport barriers. One theory attributes the formation of internal transport barriers to a gap in global wave structures in the minimum-q region. It is shown that in general no such gap exists, and that energy transport is smooth and increasing across such a minimum-q region.
