本文用解析方法研究了无碰撞俘获电子模（TEM）湍流中带状流的产生。TEM湍流的简化模型是基于反应漂移波的先进流体模型。导出了带状流生长速率的解析表达式，并与线性TEM生长进行了比较，并对典型托卡马克参数值进行了等离子体参数定标。
In the present work the generation of zonal flows in collisionless trapped electron mode (TEM) turbulence is studied analytically. A reduced model for TEM turbulence is utilized based on an advanced fluid model for reactive drift waves. An analytical expression for the zonal flow growth rate is derived and compared with the linear TEM growth, and its scaling with plasma parameters is examined for typical tokamak parameter values.
