In the theoretical investigation, we calculate the static load-deflection curves and the longitudinal forces transmission for a specified angle difference between the fixed clamp and the moving clamp. To study the stability of the equilibrium configuration, we superpose the equilibrium configuration with a small perturbation and calculate the natural frequencies of the deformed elastica. In addition, the condition where two ends with identical angles are introduced will be researched.

Distribution ratios of complex extraction for different operation conditions were forecasted. Using mass action law, the liquid-liquid equilibrium models of complex extraction of monobasic and polybasic carboxylic acid have been successfully induced, and physical extraction were also considered in the model. On the basis of orthogonal experiments, the models of equilibrium distribution ratios were established. The processes of complex extraction were tested and verified. Comparing experimental data with model values, it could be held that the regression precision of model was rather high and the model supplied fundamental data for industrial amplification and practical use of complex extraction.
