Cu-doped TiO2 nanofibers with an average diameter of about 80 nm are synthesized through an electrospinning method. Both anatase and rutile crystallographic structures are found in the fibers based on XRD results. Compared with pure TiO2 nanofibers, the Cu-doped TiO2 nanofibers exhibit improved CO sensing properties at 300°C. The sensitivity of Cu-doped TiO2 nanofibers is up to 3 when the sensor is exposed to 5 ppm CO, and the response and recovery times are about 4 and 8 s, respectively. Good selectivity is also observed in our investigations. These results indicate that the Cu-doped TiO2 nanofibers can be used to fabricate high performance CO sensors in practice.

OBJECTIVE: To investigate the effects of Yiqibushenhuoxue decoction on stable chronic obstructive pulmonary disease(COPD) by observing its influences on patients' quality of life and airway ***: Seventy patients with stable COPD were randomly divided into a treatment group(n=35) treated with Yiqibushenhuoxue decoction plus Seretide and a control group(n=35) treated with Seretide *** dosage of Yiqibushenhuoxue decoction was 100 mL each time, twice a day, and the dosage of Seretide was salmeterol 50 μg/fluticasone 250 μg twice a day. Both groups were treated for 12 weeks. Before and after the treatment, St George's respiratory disease questionnaire(SGRQ)scores,forced expiratory volume,and forced expiratory volume in 1 second/forced vital capacity(FEV1/FVC)were ***:The SGRQ scores in both groups were significantly lower than those before treatment(P0.05).CONCLUSION: Yiqibushenhuoxue decoction could significantly decrease the SGRQ scores in patients with stable COPD, which suggests that it is able to improve patient symptoms.

The reaction kinetics of bisphenol-S epoxy resin with methyl-acrylic acid in the presence of quaternary ammonium salt catalyst was studied. The reaction rate constants at different temperatures were determined. The reaction is first order with respect to epoxy group, zero order with respect to methylacrylic acid and 0.71 order with respect to quaternary ammonium salt catalyst, respectively. The mechanism of this reaction was discussed.

By taking Daan city in Jilin Province as a research object and by using TM image in 1989 and ETM + image in 2001 from American LANDSAT satellite,all kinds of maps and documentation,information of grassland,saline-alkalized land,cropland,water area and forestland is extracted by man-computer interactive interpretation method with ArcView and ArcInfo GIS software, and statistics data is acquired. On the basis of this the changing trend of land use types in the next ten years is forecasted and analyzed with Markov model. The results indicate that the problem of grassland degradation in the study area is quite serious.

The features of the characteristic matrix used in linear intensity correlation reconstruction methods are directly related to the quality of ghost imaging. In order to suppress the noise caused by the off-diagonal elements in the characteristic matrix, we propose a reconstruction method for ghost imaging called scalar-matrix-structured ghost imaging(SMGI). The characteristic matrix is made to approximate a scalar matrix by modifying the measurement matrix. Experimental results show that SMGI improves the peak signal-to-noise ratio of the object reconstruction significantly compared with differential ghost imaging, even in the case of a nonzero two-arm longitudinal difference, which is a promising result for practical applications.
