实验研究了圆柱形磁化低β等离子体从稳定态到漂移波湍流的转变过程。它表明,时间动力学是由时空模式,特别是行波的相互作用和不稳定。时间和时空数据的分析表明,分叉序列弱发展湍流遵循Ruelle-Takens方案。{版权} {美国物理学会}
The transition scenario from stability to drift wave turbulence is experimentally investigated in a magnetized low-{beta} plasma with cylindrical geometry. It is demonstrated that the temporal dynamics is determined by the interaction and destabilization of spatiotemporal patterns, in particular, traveling waves. The analysis of the temporal and the spatiotemporal data shows that the bifurcations sequence towards weakly developed turbulence follows the Ruelle-Takens scenario. {copyright} {ital 1997} {ital The American Physical Society}
