Fouling is the accumulation of unwanted material on components like compressor and turbine blade, which causes undesirable roughness.
Erosion is the phenomenon of abrasive removal of material from the flow path impinging on flow surfaces.
Fouling is a phenomenon of unwanted material/deposit of mineral which accumulates on the blade of the compressor or turbine.

The physical flame retardant method is to add noncombustible agents to the wood-based panel, to reduce the proportion of combustible materials, and to separate the combustible materials from the oxidant and heat source.
According to the value of limiting oxygen index, the combustible performance of materials can be divided into three groups: (1)OI<21 belongs to flammable materials; (2)OI=21～28 belongs to slow combustible materials; (3)OI>28 belongs to self extinguishing materials [9].

This network is characteristic of freeze-dried materials and described as sponge-like structure.
During the freezing process, ice crystals nucleate was from the solution and grow along the lines of thermal gradient; the subsequent lyophilization generates a porous materials [9].
After six months studies with serial euthanasia, pathological examination of the tissue around the materials show completely absorbing around 3 weeks, with normal repairing tissue and no inflammatory or adverse tissue reactions.

The higher values of breakdown voltage of ZnO varistor bulk decrease the height of arrester column and save the expensive raw material.
