基于实验先进超导托卡马克的I型边缘局域模式h模，建立了一个基座数据库。采用最常用的函数形式双曲正切函数（tanh）法对基座特性进行分析。基座梯度与基座顶部呈线性关系，归一化基座压力梯度α与电子碰撞有很强的相关性。用归一化的基座压力梯度建立基座顶值、梯度和宽度之间的关系。在等离子体的核心区域，电子温度刚度的性质反映了核心和基座温度之间的比例，而在高温区域，电子温度刚度的增加比例低于预期。然而，温度分布刚度在等离子体边缘是有限的甚至消失的，而在基座上的梯度长度比（ηe）是重要的。ηe的取值范围为0.5 ~ 2，随等离子体参数的变化而变化。底座…
A pedestal database was built based on type I edge localized mode H-modes in the Experimental Advanced Superconducting Tokamak. The most common functional form hyperbolic tangent function (tanh) method is used to analyze pedestal characteristics. The pedestal gradient scales linearly with its pedestal top and the normalized pedestal pressure gradient α shows a strong correlation with electron collisionality. The connection among pedestal top value, gradient, and width is established with the normalized pedestal pressure gradient. In the core region of the plasma, the nature of the electron temperature stiffness reflects a proportionality between core and pedestal temperature while the increase proportion is lower than that expected in the high temperature region. However, temperature profile stiffness is limited or even disappears at the edge of the plasma, while the gradient length ratio ( ηe) on the pedestal is important. The range of ηe is from 0.5 to 2, varying with the plasma parameters. The pedestal...
