查询词典 developable

It analyzes the development of modern industrial construction from 1970s, and with the modern architectural theory it summarizes the tendency of modern industrial buildings: When practicing the planning and the designing, it follows the theory of urban designing, and combines the factors of the architectonics, the urban planning,and the Landscaping together. While taking architecture techniques into practice, it emphasizes the combination of high-tech skills and industrial aesthetics and it exhibits the new styles of industrial building as well. It cares for the demanding of people and creates comfortable working environment. For protecting ecosystem, it stresses the developable function of industrial architectural designing, the communication with society and the enhancement of the social function of industrial construction.
