The green transformation is an important direction of the transformation of oil-gas resource-based cities. From the three aspects of environmental protection, resource utilization and transformation, a comprehensive evaluation index system for the competitiveness of the green transformation of oil-gas resources-based cities has been established, and the entropy method has been used to determine the index weights and the correlation matrix method to calculate the comprehensive evaluation score. The green transformation competitiveness of 10 typical oil-gas resources-based cities in China is evaluated. The results show that the green transformation effect of oil-gas resources-based cities in China is generally not obvious. Different cities have very obvious differences in transformation structures.

Abstract-Based on the virtual simulation theory, we used three-dimensional modeling software to build modeling road facilities (vehicles, trees, street lights, etc.) for simulating the accident environment, and by using OpenGL technology, achieved reading, displaying and controlling the threedimensional models. This dynamically realized the threedimensional animated simulation of vehicle movement. Simultaneously we have calculated in progress the simulation of vehicle crash with the basic theory of automobile collision, vehicle collision model and the law of conservation of energy and momentum. Finally, we constructed a flexible platform for the simulation experiment. The platform is enabling to add and update road, trees, street lamps and house on the simulation environment dynamically, and has ability to analysis the traffic accident. This could give an assistant to the handling traffic accidents.

Digital technology and its use in architecture support the construction industry in transitioning to more sustainable building development. Digital technology is widely taught in architecture programs in China, but there are few consistent strategies for combining digital architectural design with traditional architectural design in architectural education. Consequently, sustainable design concepts are not included in digital architectural design courses, and thus architectural education is not concerned with sustainable development. In this paper, we focus on the teaching of digital design in architecture and investigate how digital architectural design teaching can incorporate sustainability. Data from 15 universities were qualitatively analyzed, leading to the development of four models of teaching digital architectural design. Development of the models revealed that there are three increasing levels in digital architectural design teaching and that there is a close relationship between the teaching level and the transfer of architectural knowledge. This recognition led to the development of a single comprehensive model of digital architectural design teaching that is universally applicable. This research increases our understanding of digital architectural design teaching in architecture programs and strengthens the multi-level connections between digital architectural design teaching and designing and constructing sustainable built objects.

According to a certain type of equipment, an order device test system is designed. The test system can totally accomplish whole machine performance test. For its handy operation, the time for equipment test and troubleshooting is greatly shortened, while the field battle mobile support capacity of this typed missile equipment is improved effectively.

This research focus on the philanthropic aged service model with information technology in order to promote the development of the philanthropic model. This paper analyzes the specific requirements of Time banking, the advantages of architecture and J2EE platform from the technical point of view, completes the design of the system, and implements the management information system based on WEB based on MVC mode. This paper puts forward the construction of a comprehensive philanthropic mutual-aid endowment management system-Time banking to solve the problem of implementing the philanthropic mutual-aid endowment model, and discusses the functions, characteristics and functions of philanthropic endowment Time banking. 1
