The experiment uses 100% city garbage melting slag instead of nature macadam and sand to make concrete specimens, under homoiothermal (20±2)℃ and constant humidity relative humidity (60±5)%, which dry and shrink freely 180d. The results show, comparing with common concrete specimens, whose drying shrinkage length valuable rate and mass loss rate change a little.

试验以100 %城市垃圾熔渣骨料替代天然碎石和砂子制备城市垃圾熔渣混凝土试件，在恒温(20±2)℃，恒湿相对湿度(60±5)%的试验室内使混凝土试件自由干燥收缩180 d，试验结果，城市垃圾熔渣混凝土试件与对比用的普通混凝土试件相比，干燥收缩长度变化率以及质量损失率相差不大。

On the base of infection of urban waterfront space from the elements of zoology,culture,landscape architecture ,economy,city function; the design principles are separated into advantage,equalment, hydrophile, zoology, economy.

Said Zhang Jisheng Shenzhen trip productive, not only because Zhang Jisheng received "in 2004 to promote the urbanization process of China's ten most outstanding contribution to people" of awards and selected urban Sanlian "Chinese cities operator 50", is more important is that some domestic experts and scholars and the media on the Sanlian Group,"a city" model to give a high degree of recognition, this is the most important.
