Progress of statistical modelling of thermal transport of fusion plasmas based on (2–4 a) a transport analysis database is described. Statistically induced ion and electron thermal diffusivities are checked with an actual discharge which had not been included in the database. Usefulness of this statistical approach is explained in terms of (1) extracting important parameters through the application of information criterion, and (2) making possible for discussing exponents of regression expression and then implying the thermal transport property. The statistical approach reported in this paper could provide a new insight for thermal transport modelling for fusion plasmas, complementing conventional global scalings on the energy confinement time.

聚变等离子体热输运统计模型的进展

描述了基于（2-4 a）输运分析数据库的聚变等离子体热输运统计建模的进展。统计诱发的离子和电子的热扩散率通过实际放电进行检查，而实际放电尚未包含在数据库中。通过（1）通过应用信息准则提取重要参数，以及（2）讨论回归表达式的指数然后暗示热传递性质，可以解释这种统计方法的有用性。本文报道的统计方法可以为聚变等离子体的热输运模型提供新的见解，补充常规的全球能量限制时间尺度。
