Low carbon development is a development pattern to enable social and economic progress along the path of sustainable development. This paper analyzes the low carbon development situation and trend in the China's Yangtze River Delta region, one of the most important industrial and economic centers of China. The results indicate low carbon development in this region continues to move forward. However, many barriers, such as unbalanced energy consumption structure and limited research and development capability still exist. Some solutions to overcoming the barriers are proposed in the paper, covering policy, strategic, technological, educational measures.

Considering the dynamic interaction between a die structure and its soil, the dynamic characteristics of a die structure with a deeply embedded spherical biogas digester is presented in the frequency domain. Based on the viscoelastic theory, the analytical solutions for the displacement and stress of the soil are derived by the potential functions. The die structure is treated as a viscoelastic medium with a fractional derivative constitutive relation. Based on the viscoelastic theory, the analytical solution for the dynamic response of the die structure is obtained. The specific expressions of undetermined coefficients are determined based on continuity conditions. The dynamic responses of different types of viscoelastic die structures are compared, and the influences of the parameters for fractional derivative constitutive parameters, the soil and the die structure on the system dynamic characteristics are analyzed. The results show that the viscous of a die structure has a significant influence on the dynamic response of the system. The response amplitudes of a die structure decrease gradually as the thickness of the die structure increases. With the order increasing, the system-resonance effect is weakening. With the material parameter ratio Tσ/Tε increasing, the system-response amplitudes are decreasing.

By strong alkali (acid) titration strong acid (alkali), alkali (acid) titration mono-weak acid (alkali), precipitation titration and coordination titration to drop by half a drop, and settling the titration error specific terms, to illustrate the macro titration analysis would like to have drop half a drop of a solution. When strong alkali titrate strong acid or monobasic weak acid, there is no need to drop half a drop. As strong acid titrate strong alkali, there is must to drop half a drop as methyl orange for indicator. But phenolphthalein as indicator, there is doesn't need to drop half a drop. Strong alkali titrate monobasic weak acid, there is no need to drop half a drop. Eriochrome Black T for indicator titrate magnesium ion with EDTA, there is must to drop half a drop. Titration of zinc by EDTA, don't need to drop half a drop. Titration chloride ion with Moore method can not drop half a drop. © (2011) Trans Tech Publications, Switzerland.

The key of the portfolio investment problem is how to find out a reasonable portfolio to make the collocation between risk and return more efficient. A new portfolio investment model including transaction fee was established based on the single-index method, and the simulations show that the model can be solved reasonably and effectively by use of adaptive genetic algorithm. © Springer-Verlag Berlin Heidelberg 2014.

This paper explains how the concept of the Huizhou woodcarving motifs is associated with the ancient architecture which came under the influence of Chinese culture. The motifs created have been found to be adapted to Confucian thought. Generally, the Huizhou woodcarving motifs have its own guiding principles which the function and style combine strongly. Basically, the Huizhou woodcarving motifs can be categorized into decorative motifs or patterns which include flowers, birds, landscape, characters, living scene, mascots and so on. Discussion on the Huizhou Woodcarving Motifs is significative things. Redesign the motifs can preserve the traditional culture and improve art in China. © (2013) Trans Tech Publications, Switzerland.

In this paper, improved information entropy model and SOM neural networks are proposed for evaluating technical and tactical abilities of football teams in Euro 2012.Information entropy model is an effective performance evaluation tool. As a fine clustering tool, SOM has been used widely. The approach make input space cluster automatically and the learning process of clustering doesn’t need supervision. At the same time, eleven indicators that reflect technical and tactical ability of football teams are selected. Then, by means of entropy method and clustering analysis with statistic data of Euro 2012, characteristic and law is discovered between competition results and technical and tactical abilities, and a method for comprehensive assessment of technical and tactical abilities of football teams was proposed. © 2014 SERSC.

PE teaching score is a direct reflection of the quality of teaching, and the statistic analysis of the grade is an important part of the physical teaching process. Teachers can draw their own teaching effectiveness and know how students are getting along with study, through the analysis of the results, which make exams truly serving the quality education. How to do teaching analysis better and faster is a very important issue. In this paper, we study on the methods and procedures of PE teaching statistic analysis based on SPSS software, and provide an approach for the analysis of the scores in PE teaching. © 2005 - 2013 JATIT & LLS.

With poly aluminum ferric silicate (II) and magnesium (PSAFMS) coagulation treatment of four kinds of reactive dyes, through the determination of its absorbance with coagulation time changes, studied the coagulation reaction kinetics problems, as PSAFMS coagulant development would lay the theoretical foundation of application. Under coagulation condition that the water temperature was 8°C, pH=11, PSAFMS coagulant dosage was 10 ml/L, in 3 minutes the decolorization rate of reactive red RSB was 94.6%, reactive blue 3GF was 93.3%, reactive navy blue S-G was 80.8% and reactive yellow M-3RE was 75%. Different reactive dye decolorization rate is differences. It is related to dye molecular structure and particle size of the radius. From ln(ρ0/ρt)-t, (1/ρ0-1/ρt)-t relation curve of the linear correlation coefficient, the first-order reaction of the linear correlation coefficient than the secondary correlation coefficient was better, and more than 0.9668, so PSAFMS coagulant with reactive dye decolorization reaction is the first-order. The rate equations for the ln(ρ0/ρt) = kt, just different reactive dye has different reaction rate constant. © (2012) Trans Tech Publications, Switzerland.

Titanium oxide anatase (101) thin films were grown on Si substrate using reactive DC magnetron sputtering under the argon and oxygen mixture gas. Not only the effect of sputtering power and deposition temperature effects on phase structure, but also the effect of morphology on hydrophobic properties were investigated. The X-ray diffraction (XRD) results show that the rutile phase is dominant at room temperature whereas the anatase phase is formed at 600℃. Water contact angle and surface roughness measured results reveal that hydrophobicity is power dependent. When the power is set at 30 W, the surface roughness and contact angle are 117 nm and 103.7°, respectively. Increasing the power to 60 W, a local maximum contact angle is obtained at 122.1° with the maximum intensity of anatase (101) peak. When magnetron sputtering power increases to 120 W, the preferential orientation of anatase (101) keeps improving, and the surface roughness rises to 416 nm, but the contact angle decreases. © 2015, Chinese Ceramic Society.
