This letter describes a 2-dimensional finite element model used to simulate flow and transport processes in geologic media. The model was developed by the Nuclear Regulatory Commission, for the use in the analysis of deep geologic nuclear waste-disposal facilities. The mathematical model is a fully transient, compressible and 2-dimensional model which

China City Planning Review 2016年第1期25卷 41-49页

作者： Zhao Min Shao Lin Li Wei Qian Fang College of Architecture and Urban Planning Tongji University Shanghai Normal University Tongji University China Academy of Urban Planning & Design Shanghai Branch

Elementary educational facilities are one of the essential public service facilities in rural China. Based on case studies of two countylevel cities in central and eastern China, this paper explores issues regarding a rational allocation of elementary educational facilities in rural areas, including different allocation patterns and effects, and rural residents' views on elementary educational facilities, as well as their preference when choosing schools. This paper, on the basis of empirical studies, concludes that relevant policies and planning strategies should be adjusted in accordance with the general trends of rural population being decreasing continuously and the student pool concentrating toward towns, so as to achieve an efficient and fair allocation of elementary educational facilities.

From the perspective of urban design control, the study investigates the possibilities and approaches to reduce negative infl uences of gated communities, directly or indirectly, through effective planning policies or design strategies during the construction process. Based on empirical research of embedded-single case studies, it centers on three factors: enclosure scale, border effect, and shared facilities of gated communities, and discusses the necessity and feasibility to apply design control in gated communities as seen from different interest groups, i.e., developers, managers, users, and maintainers. Accordingly, it proposes several key design factors and implementation approaches to promote the integration of gated communities and "private-owned public space" into an urban social and spatial network.
