Abstract: This paper constructs the indicator system for evaluating eco-innovation, and studies the eco-innovation performance of 30 provinces in China in 2009 by the factor analysis method, and makes a comparison analysis with the situation of three northeastern provinces. The result shows: innovative strength, technical environment and the degree of environment protection are the key factors influencing eco-innovation performance, the innovative strength of Liaoning province is the greatest in three northeastern provinces, but it's at greater expense of environment; Heilongjiang Province has better environment for technology development, but innovative strength is weak; Jilin province has no advantage in these three factors

Abstract: In this work, diamond particle (DP), based on its excellent heat transfer property as well as electric insulativity, was adopted to enhance the thermal conductivity (k) and volume resistivity (ρ)of organic shape stabilized phase change material (SSPCM) for the first time. Using the method of in situ polymerization, PMMA serving as the supporting material and PEG acting as the PCM were compounded with the DP. Results show that the DP is physically combined with PMMA/PEG matrix, and all the samples remain solid without leakage above the melting point of the PEG. The k and ρ of the composite SSPCM obviously increased with the increase of DP content. When the mass fraction of DP is increased to 30%, the k and ρ of composite achieved 0.454 W•(m•K)^-1 and 6.12×10¹⁰ Ω•cm, respectively. It is also indicated that all the specimens provide available thermal energy storage density and thermal stability.

Abstract: LCA is the embodiment and technicalization of sustainable development, is tolerance and technical support of sustainable development. Meanwhile, LCA is the important mean and scientific method of ecological environment design, clean production audit, environmental material development too. Firstly, this thesis expatiates on the proposition background and basic intension of LCA. Secondly, the thesis summarizes domestic and foreign research actuality of LCA on this basis. Foreign LCA theoretical research has achieved great success, but still there are places not perfect either, which reflect in technological detail mainly. Because of short developing time, domestic accumulation of LCI is still far from enough. Finally, the thesis summarizes: LCA is not only applied to technological sciences and natural science, but also is applied extensively to social science, economic science, management science and international relationship etc; The implementation of LCA not only depends on LCA standard, but also depends on the implementer's exact understanding of method and target and one's own experience and technological background, and there is much limitation mainly in practical application.

Abstract: In this paper, the types, properties and selection of phase-change materials used in the wall were evaluated. The feasibility and methods to add phase change materials into the wall were discussed. The application and development situation of the phase change material wall in the practice were elaborated. Some problems to be solved are pointed out.

Abstract: Based on thermodynamic analysis, the recovery of W, Mo, Cr and V as secondary alloy from high speed steel by silicothermic process were performed. The variables effected the reduction process considered in the study were lime ratio, content of reducing agent and heating effect per unit. The experimental results showed that the recovery of W, Mo, Cr and V as secondary alloy from high speed steel grindings was feasible by silicothermic process. The recoveries of W, Mo, Cr and V were 95%, 95%, 72% and 45% respectively. The quality of secondary alloy was steady and satisfied for steel making.

Abstract: With the consumption of resources and environment deteriorating, Low-Carbon Economy which is low in energy consumption and pollution is increasingly received much attention. Improvement of the Carbon Tax Levy System is conducive to reduce the strain of carbon emissions and promote Chinese Economy to develop stably. In this paper, it was based on the importance of the Carbon Tax Levy System, and it compared the contents of different countries’ Carbon Tax Levy Systems, then it proposed the construction of the Carbon Tax Levy System with Chinese Characteristics under the Low-Carbon Economy.

Abstract: As the embedded modernization of military equipment, the equipment sustainable development faces the severe development "bottleneck", mainly include environment, energy and economy constraint etc. Therefore, this thesis attempts to introduce LCA method to the field of military equipment, establishes a systematic frame of appraisal of a three-dimension integrated structure, including equipment dimension, life cycle dimension and evaluation index dimension. Finally, this thesis puts forward some points in LCA on equipment sustainable development, including none-commensuration of decision goals, conjunction and amalgamation of data, improve the susceptibility analysis of stage etc, in order to offer some gist for the quantitative decision of equipment sustainable development.

Abstract: The paper describes the development of economy and electricity in Shanghai, builds a decomposition model of power consumption intensity, and analyzes the impacts of industrial power consumption intensity and industrial structure for the total power consumption intensity of Shanghai. Finally, the paper uses sub-scenarios to forecast electricity demand of Shanghai during Twelfth Five-Year period. The results show that the decrease of total power consumption intensity is mainly due to the decrease of industrial power consumption intensity, and the optimization of industrial structure has some contributions to the decrease of total power consumption as well.

Abstract: Solid-solid phase change material can increase the thermal storage capacity of the wall, decrease the indoor temperature fluctuation and building energy consumption when it was used in the phase change material (PCM) wall. This paper investigated experimentally the phase change temperature and latent heat of polyalcohols binary system with different component, and analyzed the feasibility of phase change wall. The results show that binary systems have suitable phase change temperature and bigger phase change latent. They are ideal phase change materials used in the wall.

Abstract: This paper studies a two-staged cleaning energy investment problem under uncertainty. It analyzes how a power generation firm may proceed with staged generation capacity investment and deployment of the carbon capture device through real options approach. The results indicate that, because of the variation fluctuation of electricity price, the investor tends to delay investing when the electricity price is lower, whereas the higher price-price ratio of CO₂ and electricity is helpful for him to deploy ahead the carbon capture device, the main reason is that the yields from the sale of CO₂ emission allowances can compensate him foe the higher operation cost of it.
