Introduction Polymer materials are widely used in human life.
These materials bring convenience to life, but also bring problems to the environment.

The value of δ18O is between +9.4‰ and +11.5‰, most samples belong to granitoid of high δ18O, and reflecting that source rock contains more crust-deprived materials.
The value of δ18O is between +1.3‰ and +8‰, most samples belong to granitoid of low-normal δ18O, and reflecting that mantle-deprived materials exist in magma.

Compared with the ordinary semi-rigid material,it’s strength and stiffness are higher,it’s frost resistance, erosion resistance and fatigue resistance are better.
We need to study the subgrade material’s compressive strength, splitting tensile strength, flexural strength and other properties.And we also need to study the relationship among them.It can be of signification for the railway construction in cold region. 1.

We observe improved performance of the modified asphalt than the base asphalt, owing to the fact that the modified asphalt is a linear viscoelastic material, with special delayed elastic deformation and recovery properties.
Materials The materials used in the experiment are 2 kinds of base asphalt (i.e., jia de shi 70# and qi lu 70#) and 4 kinds of modified asphalt, i.e., MAC Modified asphalt, Crumb Rubber Modified asphalt, Rubber Modified asphalt and SBS Modified asphalt.
Additionally, under different stress levels, similar creep compliances are observed for modified asphalt, therefore the modified asphalt can be treated as linear viscoelastic materials.
Our conclusions are: (1) Modified asphalt is a linear viscoelastic material, with delayed elastic deformation and recovery properties during unloading period, and is vulnerable to stress level, temperature and loading frequency.

Clad material manufactured by joining different materials can be considered as the stratified composite[1].
The properties of clad materials are determined by the selection of component materials to be joined and the stacking structure of different materials with various thicknesses and interface structure.

Liu et al.[10] using the first principle methods calculated the electronic properties of Cr,Mn doped AlN, they found when introducing Cr,Mn, the AlN materials convert to the half-metal magnetic materials with wide half-metal gap.
With the rise of geographer materials, a lot of kind of graphene materials received widespread attention.
This illustrate the AlN materials shows a half-metal property.
