Such removal is treated as though adding a load case to the original truss, and the re-distribution can be calculated without modifying the original global stiffness matrix. The computational efficiency of the presented method is faster by square times than that of the matrix displacement method. The results from the two methods are identical.展开更多

The explicit expressions for the potentials, energy eigenvalues, and eigenfunctions of the systems are given. The issues related to normalization of the wavefunetions and Hermiticity of the Hamiltonian are also analyzed.展开更多

This has led to a series of conflicts between government and villagers over the land. This issue has become the core of the conflict. The present from-top-to-bottom rural planning does not meet villagers＇ needs. Within the rural area, there are close social and organizational relationships, the villagers strongly demand autonomy. This has led to conflict between the state and villagers rights of autonomy. The conflict is ongoing, it has never stopped. For the purpose of this paper, the rural area of Zhejiang Province was investigated. The method of the empirical study was employed in order to comprehensively analyze the developmental stage of urban-rural relations, planning systems, the conflict process, and difficulties in the process of urbanization. The study discovered that the conflict was led by different value orientations between the two stakeholders--the government and the villagers. This resulted in a series of conflicts over land and natural resources and added to the breakdown of relationships on both sides, this was an external manifestation of value orientation on both sides. In conclusion, the paper recommends conflict resolution proposals and measures to be employed at every stage of urbanization.展开更多
