Activated carbons were prepared from Chinese Herbal Medicine residual and were used for the adsorption of Cr（VI）from waste water. The influence of pH，ion concentration，additive amount of activated carbon and adsorption time on the adsorption performance were investigated. Furthermore，the adsorption mechanism was preliminarily studied. The results were listed as followed：the activated carbon had a good effect on treatment of waste water of Cr（VI）that the adsorption conditions are pH=2，ion concentration for 80mg/L，the additive amount of activated carbon for 0.1 g and adsorption time for 1 h. The adsorption isotherm of activated carbon adsorption on Cr（VI）conformed with the Freundlich model，the quasi second order model can better describe the adsorption kinetics of the activated carbon adsorbing Cr（VI）.

Based on CO₂-NaOH system，the absorption performances of rotating packed bed with the gas-liquid distribution inducer were investigated. Furthermore，the characteristics of the absorbent flow and the performance of mass transfer resulted from the three different installation forms and structures of the gas-liquid distribution inducer were discussed. The experimental results showed that the absorption performance of rotating packed bed could be influenced by the installation of the liquid distribution inducer，when used the liquid distribution inducer in clockwise deflection and the gas distribution inducer in radial without deflection，the gas and liquid two phase were downflow contact，it can prolong the contact time of liquid absorbent and gas，obtained better mass transfer effect. Based on CO₂-NaOH system， the mass transfer coefficient in the rotating packed bed with gas-liquid distribution inducer could be 2. 83 times than that without the inducers，and the removing rate of CO₂ was increased from 43. 34% to 80. 00%.

Based on acetone-H₂O system，with stainless steel as filling，the influence of the rotorpacking shape on the mass transfer coefficient in the rotating packed bed was investigated. Furthermore，the absorption performance was also obtained under the experimental condition of the rotational speed of 630 r/min，the gas flow rate of 2 m³/h and the liquid flow rate of 100 L/h in the rotating packed bed with different packing rotor shape. The experimental results showed that the volumetric mass transfer coefficient Kyα per unit volume packing of the thin rotor was 2. 1 times of the thick rotor. Furthermore，when the gas flow rate was 2. 5 m³/h，K_yα per unit volume packing of the thin rotor was 2. 3 times of the thick rotor. The results indicated that the rotor packing shape of the large radius and small thickness were advantageous to the mass transfer process when packing volume was similar.

Novel fluorescent compounds based on dicyanomethylene-4H-pyran and benzothiadiazole scaffolds，responding to combinations of Cu²⁺，F^- and/or Br^- in a sequence dependent manner were synthesized and their recognition properties were investigated. Addition of Cu²⁺ immediately resulted in the "blue shift"，introduction of Br^- after Cu²⁺ has no detectable influence compared to Cu²⁺ ion alone，whereas F^- leads to complete quenching of fluorescence；In contrast，addition of F^- before Cu²⁺ induced only a slight reduction of fluorescence intensity at ca. 608 nm，while addition of Cu²⁺ after Br– leads to partial quenching at 608 nm with concomitant partial appearance of fluorescence emission around 485 nm. The mechanism was studied and confirmed. A logic gate is an idealized or physical device implementing a Boolean function，that is，it performs a logical operation on one or more logical inputs，and produces a single logical output. These structurally simple molecules can mimic the functionnalities of various complex logic gate such as EnYES，EnNOT，EnIMP，EnINH，EnNAND arrays by selection of inputs（nature of ions，sequence of additions and excitation wavelength）and outputs（fluorescence reading wavelength and threshold），1∶2 demultiplexer and keyboard.

Results There was significant difference between the two groups in the incision length，operation time，intraoperative blood loss，postoperative drainage，postoperative complication s（P < 0. 05）. The LPFP group incision length，operative time，intraoperative blood loss，postoperative drainage，post operative complications were higher than those of the PFN group.There was no significant difference between the two groups in the clinical healing time of fracture and the excellent and good rate in Harris score（ P > 0. 05）. Conclusion In the treatment of unstable intertrochanteric fracture of the femur ，the LPFP group has a longer incision，longer operation time，more bleeding，more postoperative complications and higher postoperative complications than PFN group. In the treatment of unstable intertrochanteric fractures should be carefully used and here recommends the PFN. But for medullary cavity is too small，and patients with larger femur anterior arch curve，LPFP is preferred.
