There is no doubt that there is an internal relationship betw een the mass line and ecological civilization construction. The mass line is a kind of epistemology,w hich requires that the party fully respect the principal status of people and the standpoint of the masses,correctly handle the relationship betw een party and masses in ecological civilization construction,not only to provide guidance for ecological civilization construction,but also to provide manpow ered,leading and institutional guarantee in the process of ecological practice. M eanw hile,the mass line is also a kind of methodology,w hich indicates how to build ecological civilization. Through ecological education and the implementation of policy and ecological law,the mass line lets cadres and the masses internalize the ecological civilization concept as public aw areness,and improves the system of ecological civilization,making all the people join into the progress of ecological civilization construction.

An algorithm is proposed for vehicle brand recognition in degrade image. It detects the front face of car based on symmetrical MSER regions,and then extracts the pyramid histogram of gradient orientation( PHOG) features for SVM to classify the vehicle brand. Experimental results indicate that this algorithm is robust to the low quality of non-uniform illumination and camera angle.

The subject of Bei sentences in Chinese can be a locative role,w hich helps to constitute locative Bei sentences. Locative roles in Bei sentences can be positional phrases or locative w ords. The recognition of locative roles in the subject position of Bei sentences usually involve locative markers and case relations of verbs,in w hich the former can identify the locative status of the locative roles and the concrete positions of the objects,w hile the latter are based on verb valance and can identify the types and typicality of locative roles. Both of the tw o w ays have advantages and limitations. Sentence pattern valence based on construction grammar can compensate for the limitations of verb valance by stressing on the influence of the sentence pattern meaning and the characteristics of sentence pattern. This study show s that the combination of the verb valence and sentence pattern valence in studying the interaction betw een verbs and sentence patterns in depth can help to comprehend the location role in the subject position of Bei sentences more comprehensively and accurately.

The production has rich nutrition,good sensory quality and stability.
Taking a main certain type of boom in working device for backhoe hydraulic excavator as research object,three-dimensional(3D) model of boom is established by using 3D parametric design software Pro / E. Through designing of seamless interface of ANSYS and Pro / E software,the boomu0027s 3D model is successfully imported into software ANSYS to establish finite element analysis model,and then the optimization analysis of boomu0027s performance is carried out by using the OPT module in ANSYS as the research platform. With taking the boom of minimum volume( lightest weight) as the optimization target,the effect by using optimization design method in practice is finally analyzed. The results before and after optimization show that,the optimization analysis method can effectively enhance the design efficiency of product based on finite element technology,which providing theory reference for the similar parts of structure optimization.
This paper used the software of Fluent to simulate the hot wind flow field of Coating machineu0027s dryer air nozzle,and got the distribution characteristic of the hot wind in the nozzle,found out the reasons that made the hot wind in the outlet fluctuate greatly. Then some optimization measures were put on to even the hot wind in the outlet,and reduced the effect that caused by the eddy. Thus this paper can make some reference to improve the dry effect.
Through adding different metal ions in the culture medium,inoculated fusarium oxysporum after shaking flask fermentation,determination of pectinase are three components in fermented liquid enzyme( Polygalactuonatelyase PG,Polygalactuonatelyase PL,Petinesterase PE) enzyme activity,discuss different types of metal ions,adding amount on the influence of the pectic enzyme activity. The experimental results show that 0. 06% Mg2+,0. 04% Fe2+raise PG enzyme activity of 205. 62 U / m L,297. 33 U / m L,1. 07 times,1. 45 times higher than that of control group,respectively. When Fe2+concentration was 0. 08%,PL enzyme activity reached 283. 31 U /m L,2. 83 times of the control group,indicating Fe2+plays a role of promoting PL enzyme activity. Fe2+,Zn2+have a significant role in promoting PE enzyme activity,the influence of the concentration of 0. 06% when the maximum 255. 67 U / m L,200. 68 U / m L,2. 40 times and 1. 66 times of the control group. The experimental results of metal ions enhance the vitality of pectinase different components has the reference value,in order to improve the enzyme activity to make it more efficient,fast,the degradation of citrus sacs,realize industrialization of fruit and vegetable cleaning and processing and production to provide the reference.

In this study,the Spatial Dynamic Panel M odel is used to analyze influencing factors and spatio-temporal characteristics of China's commercial housing prices using provincial panel data from2003 to 2012. The results demonstrate that land price,supply of commercial residential building and per capita disposable income of urban dw ellers are key influencing factors to housing prices. M eanw hile,the housing prices have dynamic inertia effect in time and regional correlation characteristics in space,i. e.mutual influence of housing prices in neighboring areas or areas w ith similar economic features is higher than that in nonadjacent areas or areas w ith dissimilar economic features.
