Abstract: With the arrival of an era of low-carbon economy, the planning and development of energy industry comes into global limelight. And the development of China’s energy industry faces both opportunities and challenges. This paper gives an introduction of some countries’ energy development, and studies some of their advanced measures and ideas. The paper then states the current status in China’s energy industry development, analyses the existing problems, and brings forward opinions on fueling the development of China’s energy industry, thus promoting the adjustment of energy structure and industrial structure towards low-carbon economy in order to enhance international competitiveness.

Abstract: This document explains the concept of new energy and the significance of its development and utilization, then it discusses the characteristics, energy conversion form, application methods and efficiency of solar, wind, biomass, geothermal and ocean energy, lastly, it puts forward some suggestions on how to develop new energy.

Abstract: For studying the circular mechanism and the operating mode of modern mine, this paper reviewed the current development situations of circular economy modes and some typical circular economy parks in coal mining industry at home and abroad. With the Xishan coal mine areas as the investigated objective, which operated by Xishan Coal-electricity Group in Shanxi Province of China, the characterized circular economy mode is put forwarded and concluded as “33386” development mode. Furthermore, the structure and industrial chains of Xishan circular economy system are researched in whole and interpreted in part. This is a successful attempt on the coal mining industry with a new development mode and a complete circulation of resourses in practice.

Abstract: The sustainable development culture is a culture aiming to bring culture itself into harmony with the times, promote social all-round progress and human overall and sustainable development. In today’s china, this culture is particularly needed because of the ecological crisis and population pressure we are facing, the present state of Chinese culture and the pressing need of China for construction of cultural soft power. In the construction of sustainable development culture, special attention should be given to cultural selection, education popularization and system guarantee.

Abstract: Automatic Control Theory is a required course of great importance for students who major in automation. During the winter semester of 2010, School of Mechatronics Engineering and Automation of Shanghai University has launched a bilingual-teaching program on Automatic Control Theory for the first time. This paper explores the contents, methods and models of bilingual-teaching in Automatic Control Theory based on the experience and review of this program in Shanghai University. Some methods and measures are proposed in this paper to improve the quality of bilingual-teaching in Automatic Control Theory by making analysis after the collection of students’ survey results.

Abstract: Financial innovation and financial risk often emerge at the same time. On one hand, financial innovation can transfer and disperse part of financial risks. On the other hand, financial innovation can also produce new risk factors. If the financial institutes want to put up any carbon financial innovation in the low-carbon economy time, they must improve their risk consciousness, keep away and control financial risk. This paper discusses the potential financial risks in carbon financial innovation, and brings forward relevant policy advices.

Abstract: The solution redistribution was an important phenomenon during the solidification of multi-component alloys. The different paths of solidification of different component Al-Si-Mg alloys were calculated in this paper. The calculations were coupled with CALPHAD technology. The interaction of solutes would change the solute redistribution coefficients during the solidification especially in the ends of solidification. The solidification paths were calculated by employing the CALPHAD technology and the binary partition coefficients separately. The results show that errors exist under assuming the partition coefficients of solutes as a constant due to the interaction between solutes in ternary alloys. The predicted solidification processes of Al-Si-Mg alloys agree well with the experimental results in this paper.

Abstract: This paper make use of Gravity Model, calculate evolution path of the economic gravity center and air pollutants gravity center in Shaanxi Province adoption the past 10 years (1999 ~ 2008), economic and environmental data. Research shows: economic center of gravity shifted towards the northwest and offset in the north-south direction than east-west extent of the degree of deviation. Air pollutants gravity center is also the focus shifted to the northeast, but the deviation is less than the economic gravity center shift. Air pollution emissions and economic gravity center there are positive correlation, and the center and the dust generated SO₂ emissions from the center of gravity strong positive correlation.

Abstract: The Ability of Symbiotic Innovation in Sustainable Technology (ASIST) plays an important role in the sustainable development. It is of great strategic significance for enterprises to evaluate this ability scientifically and rationally. How can we evaluate it in a scientific, rational, standardized and quantitative way In this paper the author thinks that ASIST is an ability system of multifaceted and multileveled components, such as the abilities of symbiosis with economic, social, natural and scientific & technological resource environment. The evaluation of this ability is a problem of multifactor, multilevel and fuzzy comprehensive decision, so it is reasonable and effective to select and apply the method of Fuzzy Comprehensive Evaluation (FCE). After constructing an evaluation index system composed of 4 factors and 15 indexes, the author proposes and analyses preliminarily the general models and process to evaluate the ability using FCE. The models include the basic, multilevel and multioperator ones and the process composes of 5 main steps. He further illustrates the general solution of the fuzzy comprehensive evaluation of ASIST with a practical example, in the hope of realizing the evaluation to be scientific, rational, standardized and quantitative.

Abstract: Neural network models have widely been applied in assessment and perdition of economic and social fields, including risk assessment. Thus, it becomes a subject for the theory of neural network to study how to improve accuracy in the premise of ensuring convergence rate of BP (Back Propagation) neural network. On the basis of recent studies and disadvantages of traditional BP neural network, in terms of structural optimization to improve accuracy, the paper presents a variable-structure neural network where it is re-linking randomly process from neurons of input layer to neurons of output layer and from neurons of hidden layer to neurons of output layer. Secondly, the variable structure neural network of re-linking random process is applied in freeway investment risk assessment. Results of a cast indicate that the proposed model is sufficiently reasonably.
