一系列精心设计的DIII-D实验利用了广泛的湍流和剖面诊断来严格测试陀螺湍流模拟。在本文中，这些验证研究的目标，工具和实验进行了审查和具体的例子。研究发现，核心中部区域（0.4 < ρ < 0.75）的输运和涨落能级的预测比外部区域（ρ 0.75）更符合实验，其中边缘耦合效应可能变得越来越重要，多尺度模拟也可能是必要的。诸如此类的验证研究对于建立对ITER基于第一原理的预测能力的信心至关重要。
A series of carefully designed experiments on DIII-D have taken advantage of a broad set of turbulence and profile diagnostics to rigorously test gyrokinetic turbulence simulations. In this paper the goals, tools and experiments performed in these validation studies are reviewed and specific examples presented. It is found that predictions of transport and fluctuation levels in the mid-core region (0.4 < ρ < 0.75) are in better agreement with experiment than those in the outer region (ρ ⩾ 0.75) where edge coupling effects may become increasingly important and multiscale simulations may also be necessary. Validation studies such as these are crucial in developing confidence in a first-principles based predictive capability for ITER.
