Because the composting materials in the form of polymer are very rich, all kinds of microorganism secretion of extracellular enzyme are also varied.
Materials and methods The sludge samples in this experiment were all taken from Zhengzhou Bagang sludge disposal plant, there the sewage sludge was treated with the high temperature and solid state aerobic tank type (double throw and aerobic composting) process.

The above experimental results show that the size dependence in intrinsic to certain materials, hence accurate understanding and characterization of materials response at small scale is very important in the optimal design of MEMS as well as in evaluating their reliability and performance.
To reduce the difficulties of determining length scale parameters of materials by experiments, gradient elasticity theories of only one additional material constant have been developed.

In this study, the glass fiber-reinforced composite-laminated materials were used to analyze the stabilities of wind blades, because high specific strength and excellent fatigue characteristics can be obtained by using the composites, especially glass-fiber-reinforced material.
The E-glass/epoxy orthotropic materials DBL800, L900 were employed for construction of composite laminate shell structure.
