Al-Si alloys class is an important group of materials that are used mainly in the form of sheet, plate extrusion and pipes.
Dilatometer analysis In order to determine the behavior of metallic materials subjected to heating, maintaining and/or cooling, a dilatometer analysis was applied.
By dilatometer analysis we can determine the changes of length due to temperature of the analyzed materials.
In principle, samples (solids, liquids, powders, bulk materials, sheets and fibers) placed onto the samples are heated or cooled linear.

This paper explains that the origin of the technique of cotton cultivation in China needs further demonstration according to historical data and archaeological materials.
Scholars from Shanghai Textile Science and Technology Research Institute proved that this cotton cloth’s cotton fiber was similar to the cotton blanket which was unearthed from Gao tomb of Lanxi, Zhejiang Province in the Southern Song Dynasty (Fig2), as well as the ceiba of modern Hainan Island [3].
Because of these arguments, the origin of the cotton cultivation in China needs further archeological discoveries and demonstrations The Spread of the Technique of Ancient Cotton Cultivation in Ancient China According to the literary texts before Tang Dynasty,[4] the technique of cotton cultivation before Tang Dynasty was mainly popularized in Yunnan, Hainan, Guangdong, Guangxi, Fujian, and Guizhou Provinces, etc. 2.1 The shrub ceiba and Levant cotton in ancient southwest China The ancient southwest area started from the perennial ceiba,[5] which was similar to the cotton described in the Indian archeological materials.
The cottonseed was small with thick quilt and short flock; it was ash black with brownness and well tended appearance, which was identified by Chinese Academy of Agricultural Sciences as cottonseed, namely African cottonseed.

At the beginning of this century, P.G.Nutting and A.Gemant found that the performance of the polymer materials associated with the fractional power of frequency, and the fractional derivative theory was introduced to describe gradually viscoelastic material constitutive relation [4-9].
With the development of nonlinear science, fractional derivative constitutive model will promote the development of soil mechanics, rheology theory and other related disciplines.
