The result indicated that the point of the highest temperature located on the middle of firebox which under the dangerous temperature of the material; under thermal stress effect, the max displacement of the piston did not exceed the clearance between piston and cylinder liner, but the non-roundness at the third ring reached 0.08mm, which had some influence on the pressurize and lubricate of piston; under thermal-mechanism coupled effect, the point of max stress located on the interface of the seat of the pin and the pin hole, so as the top on the pin hole and inner on the seat of pin, so it was recommended to set rib between cervix and the seat of pin of piston to enhance the practical carrying capacity of the seat of the pin.
The max stress in the whole stress field was 127.75MPa which was under the ultimate press of the material: 230MPa.

Many perovskite materials have been reported to have high proton conductivity.
Therefore, it is possible to use Zr to substitute partial Ce to get a material with both high conductivity and high stability [3].

Materials and methods Materials Dewatered PMS was obtained from a local paper mill in Dongguan city, Guangdong, China.
The physical and chemical properties of bio-drying materials were shown in Table 1.
The aerobic process was operated with continuous ventilation and the bio-drying materials were turned every 2days manually.
Turning made the materials homogeneous and eliminated the moisture gradient.

Solution to this problem lies with bringing the subsurface layer into a state of higher ductility while retaining its hardness at high enough level, for instance by nanostructuring which serves both for reducing the strain localization scale level and increasing the volume of material subject to deformation [1, 2].
