Study on Typical Traditional Silk looms in Shanxi Province Lu Wei1, a, Yang Xiaoming2,b 1.2Textile College, Donghua University, Shanghai, 201620, China areed@mail.dhu.edu.cn, bynide@sina.com Key words: traditional loom; textile technology; silk weaving; textile engineering; Abstract.
This thesis focuses on the key parts and functions of silk looms, explains the operation mechanism, and also compares the similar looms in different regions.
Taking the traditional textile industry for example, there are many different bases and centers, for example, raw materials production, silk reeling, silkworm breeding, knit silken, weaving cotton cloth and embroidery.Therefore, the prosperity of the commodity economy push ahead the development of traditional handicraft industry.
According the precious materials, including Tian Gong Kai Wu, Zi Ren Yi Zhi and other scholar’s explanation[2], the laying loom was originated from Ming dynasty, and came down until 1980s.
And it is the important part of Chinese traditional textile engineering.

Now retroreflective materials are used widely in traffic field.
But as for retroreflective materials of horizontal coatings, using handle instrument is common.
Retroreflective performance is the key technical index of retroreflective materials.
The key index of the components is listed as follows.

Due to release and accumulation of industrial contaminants in natural soil in some regions, and the long-term interaction between leachate and clay which is adopted as isolation material of contaminants, the engineering property variation of clay soils after having been polluted by heavy metal ions gradually has drawn more and more attention of environmental geotechnical engineers.
Due to the adsorption effect of clay soil, the concentration of contaminants will continually accumulated in the barrier materials.
Actually, the effect of pore fluid chemistry on engineering properties of clays has been of great interest to geotechnical engineers [3-5].
As more and more engineering problems about heavy metal-contaminated clay were met with recently, some researchers began to pay attention to its engineering behaviour and corresponding mechanism.
