However, the covalent bond of SiC is very strong, which results in a small diffusion coefficient of C, Si atoms and low sintering diffusion rate, so it is difficult to prepare high-density SiC materials by ordinary non-pressurized sintering and must introduce a second phase to promote sintering.
However, the fracture toughness is low, which limits its widely used as structural materials [4].

In the process of modeling, assuming that piston rod material was isotropic, density distribution was uniform and that the piston rod was always in the elasticity of the material[2]; The piston rod assumed to be the ideal state.
Although the maximum working stress is less than the ultimate strength of the material, stress concentration in the area of local caused small micro crack initiation, with an increasing number of cycles, micro crack expanded gradually, finally to transient faults.
Maximum stress value of the piston rod with rounded corners was still less than the ultimate strength of materials, but the stress concentration at the fillet resulted in the fracture of rods.

Termites are one of the most important groups of insects to destroy cellulosic materials.
The advantage of such a lignocellulose-degrading symbiotic ecosystem compared to a fungal system is a steady supply by the host with food and with constant living conditions for the hindgut microorganisms, as well as providing a mechanical rasp (mandible) for grinding down the plant material to micrometersize particles.
The wood microparticles are mixed with the termite's own cellulolytic enzymes produced in the salivary glands [11,12] , as well as facilitating the accessibility of the polymeric material by creating denaturing alkaline conditions in the midgut.

Generally, compared to methanol, it has numerous advantages, such as high self-ignition properties, miscible with diesel fuel in any desired concentration, good material compatibility, no toxicity [1, 2].
Two kinds of materials are needed.
Great progress has been achieved in Lanzhou institute of chemical physics, Chinese academy of sciences [21-22].
As for lower cost, the production costs of DMMn are higher than the production costs of DME, we could focus on the cheap materials production, such as methanol and DME, economy of scale and low cost feedstock will drive them cost low, making them competitive in the fuel market.
