The QSPR model for predicting λ is established and compared with
other models as shown in Table 6. Lazzús22 using GCM
to predict the λ at variable temperature and pressure and got
good results (R 2=0.9843,AARD =2.12%).
Compared with Chen et al.44,
Lazzus45 and He et al.56, our work
has a larger amount of data points, and obtained a higherR 2 of 0.9847, a lower AARD of 1.02 %.
Therefore, our QSPR model for λ prediction has the higher
precision.
