波动引起的通量具有突发性。因此，总粒子通量的很大一部分是由零星的，大的运输突发。当地的通量分布函数是一致的近高斯字符的波动。本文研究了TJ-1托卡马克等离子体边界区等离子体涨落和感生通量统计特性的径向依赖性。Garcia-Cortes等人，Phys. Fluids B 4，4007（1992）]和TJ-IU扭转型室管[E. Ascasibar等人，等离子体物理学和受控核聚变研究，第15届等离子体物理学和受控核聚变研究会议记录，塞维利亚（国际原子能机构维也纳，出版中）]。两种装置中湍流输运的统计特性之间有惊人的相似性。(C)1996年美国物理学会。
Fluctuation-induced fluxes have a bursty character. As a consequence, a significant part of the total particle flux is carried out by sporadic, large transport bursts. The local flux distribution function is consistent with a near-Gaussian character of the fluctuations. The radial dependence of the statistical properties of plasma fluctuations and induced fluxes have been investigated in the plasma boundary region of the TJ-I tokamak [I. Garcia-Cortes et al., Phys. Fluids B 4, 4007 (1992)] and the TJ-IU torsatron [E. Ascasibar et al., in Plasma Physics and Controlled Fusion Research, Proceedings of the 15th Conference on Plasma Physics and Controlled Nuclear Fusion Research, Seville (International Atomic Energy Agency Vienna, in press)]. There is a striking similarity between the statistical properties of turbulent transport in both devices. (C) 1996 American Institute of Physics.
