Based on the "regulation and sand, with sand sand", for the lack of sandy material source such as plant and clay in Northwest desert area, Inner Mongolia, many scholars have tried using aeolian sand resources that widely distributed alongside the highway construction, making local materials into sandy barriers bags, a new type of technical measures used to prevent sand-fixation[11,12] .
Test facilities are cold and arid regions environment in Chinese Academy of Science and indoor medium-sized environmental wind tunnel in engineering research institute.

Introduction Layered double hydroxides (LDHs) are anionic layered inorganic functional materials with unique structural characteristics and composition, including adjustable pore structures and high catalytic performance.
LDHs have wide potential applications and have gained widespread attention as catalyst carriers or catalyst materials[1, 2].
As a solid base materials, LDHs can be used as a high efficient catalyst in aldol condensation[3], transesterification[4], alcohol oxidation[5], epoxidation[6] and phenol hydroxylation[7].

In fact, majority of today’s mechanical parts are made of metal materials, most of the metal materials are magnetoconductive.
Their experimental results suggest that MR jet can efficiently correct surface figure error to high precision, with less than 30nm peak to valley error and micro roughness of less than 1nm rms on a number of materials [6, 7].

And it opens our mind to utilize body-scanning technology for deeper science research.
For scanning to become a freely used technology, we have to consider the potential use for deeper science research [1].
In China more than 75 millions woman warm jackets were produced in every year/2/. 89 patterns were collected from the fashionable journals or magazines in China and Russia, which the time is beginning from 1978.
The angle is used to present the property of textile material.
More and more science research will be engaged in with scanning system.
