摘要：This paper presents a three-stage hypothesis on the development of creative industrial clusters, which includes stages of agglomeration, interfacing, and network development. In the first stage, micro-entities concentrate geographically in a creative industrial cluster in search of resources. The second stage reflects the need for building identity. Finally, the third stage is the outcome of multi-dimensional expansion. As a creative industrial cluster develops, its focus moves from geographic concentration to division of labor and the creation of novel systems. Using this three-stage framework, this paper conducts an empirical study on Beijing's 798 District ("798"). Our study finds that the "self-destruction" phenomenon (which appeared after 798 had reached the stage of network development in a low-level capacity) is essentially the product of a squeezing effect of commercial prosperity on art production. Our study further examines four models of art-commerce integration and explains the ways in which creative industrial clusters are different from conventional industrial clusters: a creative cluster is a platform of integration for culture, commerce, and technology. Its course of development is characterized by novelty, emergence of identity through interfacing, and network cooperation.

摘要：当代中国大陆的城市充满了各种各样的元素和象征。作者指出,在城市发展中,设计师普遍采用包豪斯的技术,却忽略了该流派对精神内涵的重视。对此,作者以成都的望江公园和"望江橡树林"(楼盘)为例,以一个美国人的眼光探讨设计理念中"体"和"用"等相关文化问题。作者认为望江公园的各种自然元素中蕴含着深刻的文化母体,而楼盘名中的"橡树"也具有丰富的象征意义。

摘要：The 4-2-1 family structure has become many old people's choices under market economy circumstance. However,the community service for home care of elderly still has problems such as unsound service system, lack of resources integration, and lack of human resources etc. This paper attempts to construct new mode of cooperative governance of service for home care of elderly in urban community, explore the dynamic mechanism and implementation path for service for cooperative governance of home care of elderly in urban community,point out the power of cooperative governance of community service for home care of elderly,and accomplish institutional innovation such as cultivation of collaborative culture,open power system, flat organizational structure design and group design of public policies etc.

摘要：为了在一个试件中同时测量纯Ⅰ型和Ⅱ型裂纹的动态起裂韧度,设计了一种大尺寸双裂纹凹凸板试件,利用落锤板冲击装置开展不同加载率的落锤冲击实验。采用高精度应变片测量冲击载荷和裂纹萌生时间。采用动态有限差分程序AUTODYN建立相应的数值模型,利用试验-数值方法确定裂纹的动态起裂韧度。实验和数值研究表明,双裂纹凹凸板试样适合用于同时测量纯Ⅰ型和Ⅱ型裂纹的动态起裂韧度;动态起裂韧度随着加载率的增加而增加,裂纹萌生时间随着加载率的增加而减小;在相同加载率下,纯Ⅱ型裂纹的起裂韧度大约是纯Ⅰ型裂纹的0.5倍;随着试样底部预制裂缝长度从20 mm增加到100 mm,纯Ⅰ型裂纹的动态起裂韧度逐渐降低,表明底部预制裂纹长度越长Ⅰ型裂纹越容易起裂,但纯Ⅱ型裂纹的动态起裂韧度变化不大。
