Various materials have been developed in recent years for the coagulation and flocculation purposes.
Among them are inorganic-based coagulants, organic-based flocculants as well as hybrid materials [4].
Many materials have been developed and successfully used in removing pollutants from wastewater, there is still a need to improve their performance and reduce the cost of production.

In this paper, logistics strength was given a definition that the product of materials’ weight and distance during a period of time.
Weight of materials and the distance between operating units were two factors mainly considered in the logistics analysis.

One should mention that the design process could be analyzed not only from the perspective of the partition of the main system but also from the perspective of design, material and assembly features [1, 3].

They are unclean raw materials, loose control of mixture proportion and unreasonable construction site management.
The two main problems about quality of raw materials were found as follows.
The effect of raw materials.SMA has high requirements on raw materials.
Strictly control the quality of raw materials.

Materials and decoration.
Although materials that can cause people feel nostalgic need to be carefully thought, it is not to say that they must be very buckish.
Due to a series of physical and chemical changes and undeveloped materials science and technology, the environment color gradually faded after weathering, erosion, oxidation and these series function.
Old items are the most effective materials that can cause people nostalgic.

by element weight[6];When calculating material fee and labor fee it depend on actual market price, and it don’t take transportation of material into consideration.
In Japan arithmetic model CM1 engineering cost the highest, because material fee per tone of box-section column is 1.5 higher than H-section column, and spend more on column-beam processing time and welding quantity.

Introduction Thermal diffusivity of food and agricultural materials is one of the most important thermo-physical characteristics parameters in the design of processes, equipments, and machines needed in drying, storing, aeration and refrigeration.
Material and methods Theoretical background Thermal conductivity values of agricultural materials have been determined by either the steady-state heat flow or transient heat flow method.
For this reason, the transient heat flow method has been preferred by many researchers to determine the thermal conductivity of agricultural materials.
