摘要：

Energy confinement in W7-AS has been analyzed in terms of dimensionally exact form free functions employing Bayesian probability theory. Based upon the international stellarator database, which contains the energy content for a wide variety of variable settings, predictions for single variable scans are made. The scaling functions for density and power scans, respectively, are in quantitative agreement with data collected in W7-AS. Furthermore, the optimal model for the description of the global transport in W7-AS is identified as the collisional low-beta kinetic model. [S0031-9007(98)07405-5].
