检查了最近的自组织临界性模型生成的间歇信号的统计特性。与之前发表的在聚变等离子体边缘静电湍流中测量的等效量结果进行了成功的比较。这一结果重新确立了自组织临界性作为磁聚变装置中传输的潜在范例，克服了早期工作中指出的缺点[E.斯帕达，物理学家。莱特牧师。 86, 3032 (2001)10.1103/PhysRevLett.86.3032； V.安东尼，物理学家。莱特牧师。 87, 045001 (2001)10.1103/PhysRevLett.87.045001]。
The statistical properties of the intermittent signal generated by a recent model for self-organized criticality are examined. A successful comparison is made with previously published results of the equivalent quantities measured in the electrostatic turbulence at the edge of a fusion plasma. This result reestablishes self-organized criticality as a potential paradigm for transport in magnetic fusion devices, overriding shortcomings pointed out in earlier works [E. Spada, Phys. Rev. Lett. 86, 3032 (2001)10.1103/PhysRevLett.86.3032; V. Antoni, Phys. Rev. Lett. 87, 045001 (2001)10.1103/PhysRevLett.87.045001].
