From the stress-strain curve of materials and considering the concrete’ tension harding and compression softening, this programme uses the layered finite element model and arc-length method to analyse the bonded post-tensioned prestressed concrete frame, during the course it considers the material nonlinearity and geometric nonlinearity in the stiffness matrix.
The stress-strain relations to material .

Trim materials were tested using an impedance tube to suggest the best sound absorbing materials that can be used to mitigate the tyre cavity resonance effect.
The insert of absorbing materials inside tyre air cavity have been tested before [1-4].
The materials were fitted to the rim or filled into the tyre at static condition.
The placement of absorbent materials into the tyre inner surface was done previously but without any guideline to the attachment method or the parameters of materials [1, 4].
In impedance tube test, two trim materials were tested to determine which material has better sound absorption properties.

The materials have two important phases as fiber and matrix.
Diaz and Rubio [1] have investigated the present worlds need to replace the traditional metallic materials and conventional composites materials with non-conventional light weight composite materials.

The Complexity of Forest Ecosystem Complexity Science, which studies the complexity about all kinds of systems, is a branch of science.
Complexity science is also different from chaos.
Energy and material exchange in the forest ecosystem, transfer from one library to another, and form a series of forest ecological systems.
Thus, although the energy flow of some material is small, it has high quality.

The results showed as follow: Compared with control treatment(CK), application of organic materials significantly increased content of loosely combined in>2mm and content of stably combined, but there was markedly differences among organic materials.
Optical property combined forms of humus varied among organic materials.
Used of organic materials resulted in significant increase of loosely combined in 2-1mm comparison to the control.
Optical property of combined forms of humus varied among organic materials.
