In this phenomenon, a significant deflection from stability occurs in elastic zone of the material and can be resulted to the collapse of the structure.
Material is a Carbon/Epoxy called T300/976 commercially and has the following properties: , , , , , thickness (t) = 0.1429 mm.

As the nonmetal material has low modulus of elasticity, it negative effects caused by imprecise installation and production and be lessened.
Meanwhile, as the heat-conducting property of the nonmetal material is weak, the mating gears which clench the teeth are still made of steel or cast iron to radiate the heat.
The gap can be determined according to the following formula: are elastic modulus of axle journal material and bushing material respectively

After a year ,the completion of the project, think about the works once more you can find the caution and love of life that planners show in dealing with the relationship between man and nature , and the respect to all living and non-living, respect, and the basic ideas is the essence of reducibility strategy, mainly shows in the following three aspects: (1) Fully demonstrate Valley’s natural landscapes, and strive to minimize the amount of development (2) The reversible methods, simple structure, recycling materials, environmental protection, can be restored
(3) Permanent building is used of local natural materials to combine with the native environment

Study on Treatment and Reuse of Wastewater from Yunnan Huize Pb-Zn Ore Flotation Xiuzhi Chen1, Chunbao Sun1, Hairui Yang1 , Chuanyao Sun2 1School of Civil and Environmental Engineering University of Science and Technology Beijing, Beijing, China 2Institute of Mineral Processing Beijing General Research Institute of Mining and Metallurgy, Beijing, China xiuzhichen@sohu.com Keywords: Flotation wastewater.
Experimental Materials The galena in this experiment is collected from Yunnan Huize Pb-Zn sulfide ore.
With waste water, the recovery rate is always lower than 15% which means some material in the waste water would strongly influence the recovey of galena.
This represents that some material in wastewater affects the recovering process, and affects the recovery rate greatly.

Further, the spatial steric hindrances which arise from the high polymer reseau restrain the small molecule material diffusion, maybe result the immobilized enzyme dynamics behavior change and the activity reduce.
