It has been developing rapidly in the past 20 years, and became the latest methods and technology of social structure study, and a whole new paradigm of social sciences research.
The first period (1930s-1970s), graph theory in mathematics was introduced in social science research, and the sociogram was produced, providing a series of concepts used in the study of features of the social network.
The high welfare system has played an active role, which guaranteed every citizen the materials to live on, effectively eradicated the poverty and inequity, enhanced women’s status and promoted the stability of society. [4] Compulsion and Diversity Be compulsory means that due to the history factor, the state intervened into every welfare domain and the legal system of the welfare security is comparatively perfect.

In view of building characteristics with complicated structure, various types, and different function, this paper calculate carbon emissions referring to the Specification and other reference materials.
Through the analysis of building process of the building entity, we can see that it is a series of aggregation process, including land use, building materials and processing, material transport, construction, maintenance and demolition disposal process, which generally can be divided into physical phase, the use phase and demolition phase.
In PAS2050, the components are divided according to the materials used.
This principle is more suitable for construction product, because construction materials are numerous.
