Abstract: This article borrows ArcGIS10.0 software, which will be spatial analysis model standard deviation ellipse (Standard deviational ellipse, SDE) used to study the Guanzhong - Tianshui Economic Zone of each urban high-tech industrial clusters, each cluster to explore spatial evolution of the economic trends in the region, Empirical Study of ArcGIS software applications in a cluster aspects.

Abstract: Energy is the basic industry of the national economy, the social and economic development. It plays a very important role in the improvement of human living standards. However, in the actual planning process, a lot of the energy system complexity and uncertainty of information exists, the traditional energy model does not reflect this characteristic. Therefore, this short paper will make a brief introduction of the uncertainty of the Energy System allocation model.

Abstract: Waste PET bottles which is the main ingredients are PET (polyethylene terephthalate), is not easy to degrade under natural conditions. If without recycling rationally, waste plastic bottles will pollute the environment, that is of no advantage for “the construction of resource saving and environment-friendly society”. This paper introduces a new kind of recycling way – the technology of regenerating fibers – that will process the recycled PET bottle flakes into staple fiber (a kind of textile raw materials). And finally it can produce various raw materials of textile garments by the staple fiber. The process of PET bottle flakes recycling mainly takes five steps: sorting, separation, cleaning, crushing and using. This paper analyzes the domestic and foreign PET processing of technology on regenerating staple fiber. And it puts forward a complete set of modification technology program for regenerating staple fiber by PET on the basic of theory.

Abstract: The energy enterprise group has its basic features and value properties, and it has the driving force of pursuing maximal value. As an important internal control mechanism, the internal audit system contributes to the value creation of the enterprise. The actual operating condition of the energy enterprise group is not consistent with its market performance. The value creation and development effect has not been recognized by the investors. Ignorance of the relationship between the management authority and its operating risk may lead to the damage of the energy enterprise value. Meanwhile, the transformation and upgrade of the energy enterprise group faces both opportunities and problems, which is important for the internal audit system to be improved through five directions—strategy improvement, function expansion, organization revolution, process reengineering and safeguard mechanism to meet the demands of the enterprise value development.
