Fig. 6From: Kinetic analysis of color changes in keyaki (Zelkova serrata) and sugi (Cryptomeria japonica) wood during heat treatmentChanges in color parameters of sugi wood: best-fit model [Eq. (9)] and superposed data using only horizontal shift factor a T for L* and \( \Updelta E_{ab}^{*} \) and using both a T and vertical shift factor b T for a* and b* (error bar standard deviation)Back to article page
