An efficient micellar electrokinetic capillary chromatography method was developed to analyze three major active components including morroniside, loganin and gallic acid in Fructus corni and its six preparations for the first time. The factors that could affect the separation were studied, such as the pH of the buffer, concentrations of SDS, organic modifier and beta-CD, and the applied voltage. The optimum analysis conditions were 10 mmol/L NaH(2)PO(4)-5 mmol/L Na(2)B(4)O(7) (pH 6.8) buffer containing 140 mmol/L SDS, 1 mmol/L beta-CD, 5% (v/v) methanol and 12.5 kV applied voltage. The linearity between the peak-areas and the concentrations of the analytes were investigated, and they exhibit excellent linear behavior over the concentration ranges (correlation coefficients 0.9953-0.9995). In addition, the pK(a) of gallic acid was determined using capillary zone electrophoresis. The result was consistent with that reported by the literature.

Based on the summary of the status of land subsidence research, Biot Consolidation Theory is proposed to analyze the coupling of seepage field caused by precipitation. By use of Biot consolidation two-dimensional plane finite element calculation programmed, the land subsidence of the WenZhou Yongqiang plain caused by the exploitation of underground water was analyzed. The results are more in line with the measured data, so the method for analysis of possible land subsidence is practicable.

The research of this paper focused on bond characteristics of overlay-substrate interface in ultra-thin white topping(UTW), aim at ultra-thin concrete overlay on old concrete. Compressive and shear stress have been considered in the structural analysis and experimental research. Bonding behaviors of several surface pretreatments to old concrete have been investigated. A shear-peel test device has been developed to imitate brake-load of wheels at the plate boundary of UTW, and its analytical calculate principle have been discussed to simulate the mechanical theory of the shear peel test. Structural analysis and experimental research results indicate that various flaws are accumulated remarkably in the transition layer at overlay-substrate interface in UTW. Different surface pretreatments of the old concrete will influence on the bonding characteristics of overlay-substrate interface, chiseling treatment for interface has more contribution to working together with the new concrete, but interface adhesive agent enhances the coordination between the interface and the old concrete layer. The treatment combination of chiseling and brushing interface adhesive can effectively improve the strength of the weak interface transition layer. Shear-peel test results indicate that the interlocking influence generated by chiseling treatment is prior to brushing interface adhesive. It is necessary turn to account suitable measure to prevent ultra-thin concrete overlay peeling off from old concrete.

On the basis of LuGer friction model, an integrated sliding-mode control strategy is proposed to deal with servo system nonlinear and uncertain factors effectively. The control strategy includes two parts. One is nominal model without considering disturb and uncertain, the other is real model including disturb and uncertain. To one part, choose reasonable sliding surface and design controller law. To another part, PTSC algorithm and NNC algorithm combines together to optimize RBF neural network in order to acquire upper bound of uncertain. Simulation and experiment results show that proposed control strategy better servo system performance.
