The missile in long-term storage and use process, because of the function of temperature stress and other environmental stress, its materials will age and its service life will be affected and explosive maybe cracked.
Simulation analysis of solid transmitter after the materials ageing.
The missile in long storage process, its composite materials of thermal insulation layer's annual ageing rate isnaturally [2].
If a missile storage 8 years, the thermodynamics properties of shell and thermal insulation layer decline about, the properties of the materials after ageing is shown in Table 1.

Moreover, Sen A etc. found that it would be the most beneficial for cell adhesion when the surface contact angle of the implant materials was at 66 °[12].
The proliferation rate in the experimental group was either higher or equal to the rate of the control group, which suggested all the materials in the three groups had no inhibition on osteoblast proliferation.
Conclusion 1.The DLC:N films was successfully prepared by PVCVD method. 2.The DLC:N film has good biocompatibility, and may have potential to be applied in medicine materials.

Many factors may affect the energy absorption behavior of tubular structures made from different materials or different configurations.
For cellular materials, the concept of ESR is similar to the “densification strain”
Obviously, these KPIs can be applied in evaluating other kinds of energy absorbing strictures and materials, including cellular materials, to guide their design and archive a certain degree of optimization.

For anatase and rutile structure, they are required to be potentially active materials for various applications.
To surpass this problem, additive materials can be introduced to generate electron donor to enhance photocatalytic activity and prevent charge recombination [5-6].

Because cold rolling of spline has many advantages such as high productivity, good continuity of metal wool in tooth face, high strength, better wear resisting property of tooth face and less waste of materials, it has a broad application prospect [1].
Two kind of materials AISI-1015[70-2000F(20-1100 °C)] and AISI-1045, COLD[70F(20 °C)] were used, and the temperature of the materials and the environment is set up to 20 °C.
The average stress fields of different frictional coefficient, different materials and different rolling time were shown in Fig.4.
