    Structural relative number is one of the most important indexes in the comprehensive indexes,and is widely used.The connotation of the theory and the algorithm seems to be perfect,but in the structural analysis,some puzzling situations often appear in operation,which suggests the presence of defects in the structural relative number.In this paper,through elaborating connotation,listing the typical examples,presenting the problems,and analysing the cause of the problem,it is pointed out that the general basic structure and derivative structure must be distinguished,further refinement must be made in the aspect of algorithm,exceptions must be provided for calculating the derived structure,so that the needs of various statistical analysis can be met.

    The dynamical cooling process of a cavity opto-mechanical system is investigated by a master equation.The mean phonon number is calculated using the covariance approach.Firstly,the effect of different cavity dissipation rate on the mean phonon number is discussed in the strong coupling system.Then the variation of mean phonon number changing with different parameters in the weak and strong coupling system is compared.For strong coupling regime,the mean phonon number oscillates periodically with the increase of coupling strength and it decreases fast as the cavity dissipation rate increases.Finally,it reaches a cooling limit.In the weak coupling regime,the mean phonon number increases fast as the cavity dissipation rate increases and it reaches equilibrium in the end.

    In order to improve the accuracy and stability of circular image feature point detection,an algorithm is put forward based on the gray-scale symmetry of circular image center.Through this algorithm,the edge of circular image is firstly detected by Sobel operator;then gray-scale qualitative method is used to determine the center of the circular image;and finally gray-scale symmetry factor is introduced to obtain the sub-pixel coordinates of the feature points of circular image.Projection simulation experiment and measuring experiment are adopted to evaluate the precision of this algorithm,and the experiment results show that the precision of this method is around 0.2 pixels.

    The effects of plasticizer dibutyl phosphate (DBP) on the spectral properties,structure and catalytic activity of trypsin were investigated using fluorescence,UV-vis absorption and circular dichroism (CD) spectroscopy along with atomic force microscopy (AFM) and molecular simulation under simulative physiological conditions (pH 7.4).The result of fluorescence quenching indicated that a ground state complex was formed between DBP and trypsin through hydrogen bonds and Van Der Waals forces,resulting in the intrinsic fluorescence quenching of trypsin.There was a single class of binding sites on trypsin for DBP.Analysis of synchronous fluorescence,UV-vis absorption and CD spectra demonstrated that the addition of DBP led to the conformational alteration of trypsin,decreases in the α-helix,β-sheet and β-turn contents and an increase in the random coil content.The AFM topography image showed that the binding of DBP with trypsin caused the surface morphology change of trypsin and the protein aggregation.The molecular modeling results exhibited that the binding site of DBP on trypsin was adjacent to the S1 binding pocket,and three hydrogen bonds formed between the amino acid residues His 57,Ser 195 and Gly 193 of trypsin and the oxygen atom of DBP.The enzymatic activity assay indicated that the binding interaction led to the inhibition of the trypsin activity.

    The distribution behavior of the association complex formed by the chelating agent PAN(1-(2-pyridineazo)-2-naphthol) with Ni2+ and Tween 80 was studied in the aqueous two-phase system between isopropyl alcohol and (NH4)2SO4 solution.The results showed that the maximum absorption wavelength of associated complex was located at 562 nm which turned to the red shift of 97 nm compared with the mixture of PAN and alcohol solution.The linear range of the calibration curve was 0.10~0.60 mg/L,with the linear correlation coefficient being 0.999 2 and the apparent molar absorbance ε being 1.7×105 L·mol-1·cm-1.The interfering ions,such as lead(Ⅱ),zinc(Ⅱ),aluminum(Ⅲ),manganese(Ⅱ),molybdenum(Ⅵ),iron(Ⅲ),chromium (Ⅵ),and Ni(Ⅱ),were not extracted by the system,and the Ni(Ⅱ) was separated from the interfering ions mentioned above.

    The correlations between ground-level NO2 and O3 concentration are analyzed by the method of detrended cross-correlation analysis,based on the observational data in the urban area of Chengdu (capital of Sichuan Provincial,China) from July 1 to August 31,2013 and from January 1 to February 28,2014.The results show that the correlation between NO2 and O3 concentration are characterized by long-term persistence.Furthermore,a comparative study of the correlation of NO2 and O3 in the summer and winter is made,and the reason for the differences are analyzed.It shows that there were significant differences in meteorological conditions on the different time scale of the interaction between NO2 and O3.It was found that the differences are due to solar radiation,sunshine hours and temperature.The results help to deepen the understanding the pollution characteristic of O3 in Chengdu.

    Literatures abroad on energy consumption and carbon emissions of different building structures are reviewed,with focus on the research progress and research results about the energy consumption and carbon emissions of wooden structures,concrete structures and steel structures.The article draws the conclusion that the energy consumption and carbon emissions of wooden structures is lower than those of the concrete and steel ones;wooden structure has a carbon storage function and waste wood burning can substitute fossil fuels;at construction sites,concrete structures consume more energy than steel structures do;under the same boundary conditions,concrete structures have lower implied energy and implied carbon than steel structures;but if the steel recovery is considered,energy consumption and carbon emissions of both the structures are appropriate.This conclusion can provide reference for the domestic study on energy consumption and carbon emissions of different building structures in China.
