综述了磁约束实验中纬向流实验的现状。传统和现代诊断学的创新应用清楚地揭示了纬向流的存在、时空特征、与湍流的关系及其对限制的影响。特别是，在纬向气流的振荡分支上积累了一些观测结果，称为测地线声学模式，这表明理论有必要对其进行适当的描述。除了纬向流的这些基本性质外，一些新的方法还阐明了湍流产生纬向流的过程。强烈鼓励进一步研究纬向流动和限制之间的关系，因为跨设备的活动包括低温、环形和线性设备。
The present status of experiments on zonal flows in magnetic confinement experiments is examined. The innovative use of traditional and modem diagnostics has revealed unambiguously the existence of zonal flows, their spatio-temporal characteristics, their relationship to turbulence and their effects on confinement. In particular, a number of observations have been accumulated on the oscillatory branch of zonal flows, named geodesic acoustic modes, suggesting the necessity for theories to give their proper description. In addition to these basic properties of zonal flows, several new methods have elucidated the processes of zonal flow generation from turbulence. Further investigation of the relationship between zonal flows and confinement is strongly encouraged as cross-device activity including low temperature, toroidal and linear devices.
