提出了一种新的等离子体湍流模型，将等离子体湍流看作是由漂移波及其产生的结构、带状流、流光和大尺度模式组成的非线性系统。新范式为磁约束等离子体中尚未解决的问题提供了新的思路，如约束改善、非局域输运、同位素效应等，这些结构的识别将有助于建立输运第一性原理定律。对等离子体进行全尺寸测量是进一步了解等离子体湍流的关键。为了进一步理解湍流的物理性质，需要制作特殊的环形装置。
A new paradigm for plasma turbulence has been made; plasma turbulence is regarded as nonlinear system of drift waves and their generated structures, zonal flows, streamers, and large scale modes. New paradigm provides ways to clarify unsolved problems in magnetically confined plasma, for example, confinement improvement, nonlocal transport, isotope effect, and so on. Identification of these structures should contribute to establishing the first principle laws of transport. Full scale measurement covering the whole plasma is essential for further understanding of plasma turbulence in laboratory experiments. Special toroidal device should be made for further physical understanding of turbulence.
