Optimization of Multi-additives for Expansive Soil Improvement Using Response Surface Methodology

Controlled preparation of CaO adsorbents by microsyringe titration technology for CO2 capture

“…Figure 2(B), (D), and (F) shows the contour patterns of factors A and B, A and C, and B and C, and the contour plot of D shows a circle-like shape. Since the more circular shape of the contours indicates that the interaction between the two factors is not significant, [43][44][45] the interaction between B and C is not significant, which is consistent with the results of the analysis of variance (ANOVA) as shown in Table S5. Figure 2(b) and (f) show that the contour plots are close to an ellipse, indicating that the interactions between A and B and B and C are significant; however, from Table S5, P(AB) > 0.05 and P(BC) > 0.05, which indicates that the interactions between A and B and B and C are not significant, and the results obtained from these two aspects contradict each other.…”
