Fourth, it is the coo-industrial chain which including the recovery rate of waste materials, recycling rate of industrial water, utility ratio of Industrial Solid Waste, emissions of three waste per 10,000 Yuan of industrial output value and the effective utilization rate of energy.
The local sanitation department is responsible for collecting and unified sanitary landfill, so the recovery rate of waste materials and sewage recycling rate is relatively low.

Methods of oxidative ammonia-sulfate leaching of natural raw materials of complex composition are widely used in industry [6-7].
In this case, the general model of cascade consists of three models of reactors arranged in series and connected by material flows of reagents.
The model of each reactor consists of blocks of chemical kinetics, hydrodynamics, and material balances.

Especially, the topology optimization is referred to as the FE-based techniques for an optimal distribution of void and materials [5].
The approach presented in this paper is This research is supported by the National Natural Science Foundation of China Grant#50675027 simulated through ANSYS to verify the effectiveness and feasibility.
The assumption that the material density and material properties of the non-linear relationship as follows:    = = 1 1 vv EE a η (2) Where 1E is the elastic modulus of the actual material ( 1>α ), 1v is the Poisson's ratio.
And then we elected the material properties of the robot arm.
