Immersive virtual product development is a new desi gn , developing and evaluation method of integrated product and processing tragedie s, which using VR, multi-discipline simulation and scientific visualization tec hnologies. Users may have the experiences of being part of a cyberspace environm ent with the ability to navigate and manipulate objects which have properties an d behaviors that correspond to those of the real world objects. We present a fra mework and prototype system of an immerse VPD (IVPD) which enables users to navi gate and interact with 3D peripherals with the display system. The framework of IVPD which we have defined can meet these requirements. In the immersive virtual environment, design will include four main parts: 3D CAD/modeler, multidiscipli ne simulations, CAM and discrete system simulation. 3D CAD/modeler can create 3D geometric objects and import models from other commercial softwares such as UG, CATIA etc. It can also store all kinds of models into databases with hierarchy which will provide geometric models with simulations and evaluations in later pr ocedures. Multidiscipline simulations can integrate many simulations such as FEA , CFD, Noisy and etc. Each kind of these simulation softwares will reflect a cer tain aspect of product or component’s performances. CAM, as a successor of prod uct development, mainly simulates the manufacturing procedures in the computer. Discrete system simulation will able to see the layout problems for a factory. I t is very useful for production management. Participants may actively view the v irtual world revolving around them while others control navigation and simul ations, and may interact with other members such as pass an object from one embo died manikin to another. 展开更多

Taking Zhangye City as an example, the thesis analyzes the restricted factors of resources and environment confronted by the agriculture in arid area of Hexi Corridor: the first is the agricultural natural resources. The area of cultivated land decreases year by year, and there are sharp decrease of biological diversity as well as the shortage and waste of water resources; the second is the ecological environment. There are critical soil erosion, frequent natural disaster and outstanding agricultural area source pollution; the third is the rural economy. The agricultural structure still can not meet the need of agricultural development in recent years, and the proportion of agricultural product processing is low. It points out that implementation of agricultural recycle economy is the necessary choice of the agricultural development in Zhangye City. Developing recycle economy is conducive to improving ecological environment and realizing agricultural sustainable development; developing recycle economy can solve the agricultural area source pollution to much extent and protect rural environment; developing recycle economy is conducive to adjusting rural industrial structure, increasing job opportunities and increasing farmers' income; developing recycle economy is conducive to elevating the international competitiveness of agricultural products. The thesis also has put forward the countermeasures of developing agricultural recycle economy in Zhangye City as follows: firstly, fostering the ambience of the development of agricultural recycle economy; secondly, forming the incentive mechanism of development of agricultural recycle economy; thirdly, broadening the investment channel of development of agricultural recycle economy; fourthly, perfecting socialized service system of agricultural recycle economy. 展开更多

China's poor energy development and in-situ conversion legislation, environment laws and energy laws lead to a severe environmental issue in energy source. This paper uses comparison and logical methods to discuss Chapter 4 of Energy Law (Draft for Soliciting Opinions). Energy development is taken as a separate chapter; in-situ energy conversion is added to energy processing and conversion, common features are summarized to form general provisions and other provisions. According to respective characteristics of system for total amount control of energy development, performance guarantee system, environmental trust fund system, energy retaining system and environmental lien system, incorporate them into energy development, in-situ energy conversion and energy processing and conversion, in the hope of solving China's shortage of supply for environmental protection laws on energy development and in-situ conversion, responding to times of environmental protection, and optimizing China's Energy Law. 展开更多

From the perspective of environmental sociology,a questionnaire survey was conducted on the environmental awareness and behaviors of undergraduates from nearly all fields of majors in Sichuan Agricultural University. According to the investigation results,there are los of problems,for example,the college students generally do not have adequate knowledge about environment and are unclear about the existing na- tional ecological law system; their attitude towards environment is often influenced by their majors; their evaluation of environment is far from the reality; their environmental behaviors are weakly restrained and conserved. According to these problems,related suggestions were proposed. 展开更多
