[求助] Zview 拟合中韦伯阻抗参数 已有1人参与

小弟想用Zview拟合的韦伯阻抗计算体相锂离子扩散系数...但不了解原件参数的意义
W1-R 98.28
W1-T 180.1
W1-P 0.5302
请问这R,T,P分别代表什么,单位是什么...
以及怎样用这些参数计算锂离子扩散系数...

(PS, 我之前只用过 Zre=Re+Rct+σw*ω-0.5 这个公式,选择阻抗数据实轴计算。现在想用Zview拟合后的阻抗数据计算,可惜电化学功底比较浅,无从下爪中...)
希望各位大神不吝赐教~~
先谢过...

Finite Length Warburg - Open Circuit Terminus        

       Z = R*ctnh(^P) / (I*T*w)^P

       Parameters:        Wo-R, Wo-T, Wo-P

This element is also known as a Generalized Finite Warburg element (GFW). It is an extension of another more common element, the Finite-Length Warburg (FLW).

To use the FLW equation, set Wo-P = 0.5 and set its freedom to 'fixed'.

The FLW is the solution of the one-dimensional diffusion equation of a particle, which is completely analogous to wave transmission in a finite-length RC transmission line.

In the diffusion interpretation Wo-T = L2 / D. (L is the effective diffusion thickness, and D is the effective diffusion coefficient of the particle).

The GFW is similar to this, but for it the square root becomes a continuously varying exponent Ws-P such that 0 < Ws-P < 1.

This version of the Warburg element is terminates in a open circuit. At very low frequencies, the  Z' approaches Wo-R and Z'‘ continues to increase - similar to the behavior of a capacitor.

If the data exhibits only the high frequency (45 degree slope) behavior and not the transition to low frequency behavior, either Wo-R or Wo-T must be set as Fixed(X). Alternately, a CPE can be used in this situation.

公式里的I说是等于square root(-1),但是怎么用呀?

是 S/s0.5次方   ?  大写的S除以小写s的0.5次方,这什么意思。
